The vast treeless Nullarbor Plain isolates the inhabited areas of Western Australia Western Australia, state (1991 pop. 1,409,965), 975,920 sq mi (2,527,633 sq km), Australia, comprising the entire western part of the continent. It is bounded on the N, W, and S by the Indian Ocean. Perth is the capital.  from those of South Australia South Australia, state (1991 pop. 1,236,623), 380,070 sq mi (984,381 sq km), S central Australia. It is bounded on the S by the Indian Ocean. Kangaroo Island and many smaller islands off the south coast are included in the state. . The plain is generally considered to extend 400km west and 300km east of the Western Australia-South Australia boundary, and up to 250km inland from the Great Australian Bight Great Australian Bight, wide bay of the Indian Ocean, indenting the southern coast of Australia. An unbroken line of cliffs c.200 ft (60 m) high runs along the coast and extends inland as the arid and desolate Nullarbor Plain. . McKenzie & Robinson (1987, ix) contains an excellent, if now somewhat dated, bibliography for the Nullarbor.

Formed of limestone, the Nullarbor Plain is fairly porous so that any rainfall drains underground, resulting in no surface watercourses and few distinguishing features (Bolam, 1924, 51). The main vegetation includes saltbush saltbush

 (Atriplex spp.) and bluebush (Kochia/Maireana sedifolia), the former being "of the greatest value as forage, succulent succulent (sŭk`yələnt), any fleshy plant that belongs to one of many diverse families, among them species of cactus, aloe, stonecrop, houseleek, agave, and yucca.  and nutritious food for sheep and cattle in the driest season of the year" (Bolam, 1924, 45), and supporting about one sheep per twelve hectares (Reardon, 1996, 82). In non-drought seasons, these well-spaced subshrubs "almost disappear in a sea of grasses and forbs" (Beard, 1975, 40). The Aboriginal groups Mirning, Kokata and Wirangu lived on the periphery of the plain, which they called by the Mirning name of Gondiri, but only after rain would they venture far into it. The remarkably Aboriginal-sounding name 'Nullarbor', Latin for 'no trees', was given to the plain by South Australian surveyor Edmund Delisser, who explored into it in 1865-66 (Reardon, 1996, 13 & 33; see Delisser, 1867).

Before the arrival of Europeans, the southern fringe of the Nullarbor was crossed by Aboriginal traders (Reardon, 1996, 31). The first recorded crossing of the plain--from east to west--was by Edward John Eyre Edward John Eyre (5 August, 1815 - 30 November, 1901) was an English land explorer of the Australian continent and a controversial Governor of Jamaica. South Australia's Lake Eyre, Eyre Peninsula, Eyre Creek, Eyre Highway (the main highway from South Australia to Western , John Baxter and three Aborigines aborigines: see Australian aborigines.  in 1841, searching for an overland stock route. The expedition predominantly hugged the coast. Two of the Aborigines killed Baxter, south of present day Caiguna, and ran off, leaving Eyre and the other native, Wylie, to complete the journey to Albany (see Eyre, 1843 & 1845).

The second crossing--from west to east--was made by John Forrest Sir John Forrest, GCMG, MLA, PC (22 August 1847–2 September 1918) was an Australian explorer, the first Premier of Western Australia and a cabinet minister in Australia's first federal parliament. , later premier of Western Australia The Premier of Western Australia is the head of the executive government in the Australian State of Western Australia.

. The line was completed on 8 December 1877 when the Western Australian and South Australian lines met at Eucla (Main Roads Department, 1969; Reardon, 1996, 64). A connecting line via Balladonia and Norseman to Coolgardie was added in 1896 (Beard, 1975, 3).

Meanwhile, Ernest Giles William Ernest Powell Giles (7 July 1835 – 13 November 1897), best known as Ernest Giles, was an Australian explorer who led three major expeditions in central Australia.  had also crossed the plain, westwards to Perth in 1875, travelling 250-300km inland, north of the present railway. He returned to South Australia through the centre of Western Australia in 1876, demonstrating the superiority of camels over horses for such journeys (Main Roads Department, 1969. See Giles, 1889). Further trans-Nullarbor crossings included Alfred H.G. Heath in 1894 who drove camels for the merchant Sultan Mohammed of Kandahar, from Marree to Coolgardie (Main Roads Department, 1969; Kimber, 2002), and the remarkable Arthur C. J. Richardson, who in 1896 cycled from Coolgardie to Adelaide in 31 days of "sweating and swearing" (Opperman, 1977, 203; Serle, 1988, 379). Sheep stations were established on the Nullarbor's fringes about this time: Noondonia in 1880, Balladonia and Nanambinia in 1883, and Mundrabilla in 1892. More stations were developed in the 1930s (Beard, 1975, 4), and the 1960s.

In 1906-7, filmmaker and overlander Francis Birtles Francis Birtles (born 7 November 1882 in Melbourne, died 1 July 1941 in Sydney)[1] was an Australian adventurer who set many long-distance cycling and driving records, including becoming in 1927 the first man to drive a car from England to Australia.  cycled from Perth to Sydney unaccompanied un·ac·com·pa·nied

. The telegraph was rerouted along the railway for ease of maintenance, and transmissions via Eucla ceased in 1927 (Burke, 1991, 243 & 262 fn4; Reardon, 1996, 66 & 76).

Then in 1937, Hubert Opperman Sir Hubert Ferdinand Opperman OBE (29 May, 1904 - 24 April, 1996), affectionately referred to as Oppy by Australian and French crowds, was an Australian cyclist and politician, whose endurance cycling feats in the 1920s and 1930s earned him international acclaim. , champion cyclist and subsequent politician, outdid out·did

 Richardson's and Birtles' feats by cycling from Cottesloe beach in Perth to Bondi beach in Sydney in 13 days 10 hours 11 minutes. His backup crew included Herb Elliot, who while carefully noting road conditions for "Oppy's" attempt, was probably the first to tow a caravan across the plain. Another in the crew, Aubrey Melrose, had crossed the plain seven times. Their route followed the railway from Kalgoorlie to Rawlinna, and then turned south towards Madura Pass (Opperman, 1977, 204-5 & 211).


Before the Second World War, the 'road' to South Australia followed tracks used to transport poles during construction of the overland telegraph line, and was little more than a stock route connecting pastoral stations, hard to locate in places and impassable after rain. Wartime strategic necessity dictated that the Department of the Army, through the Main Roads Department of Western Australia, form more useable road. A road paralleling the transcontinental railway was ruled out due to the cost and effort required for construction through the numerous limestone outcrops. The eventual Norseman to Ceduna route avoided such difficulties, and was constructed from July 1941 to June 1942. Road metal was used on weak sections, but the passes at Madura and Eucla were fully constructed and sealed. Even when formed, occasional rain could still render the road impassable for several days (Main Roads Department, 1972, 1; Edmonds, 1997, 93-97 & 442-443). Traffic volume was light, but grew steadily after the war as private vehicle ownership grew. From fewer than 10 vehicles per day in June 1951, volumes increased to 20 per day by 1957 and almost 40 per day by 1963 (Main Roads Department, 1972, 1). This latter increase was due in part to the hosting of the Commonwealth Games Commonwealth games, series of amateur athletic meets held among citizens of countries in the Commonwealth of Nations. Originated (1930) as the British Empire games, the series is held every four years and is patterned after the Olympic games; women have participated  in Perth in 1962 which attracted a reasonable number of interstate visitors (Main Roads Department, 1969).

The long unsealed road was notorious for its potholes and difficulties after rain, as attested by entries in the John Eyre motel register:

Such traffic and tourism increases, and the economic importance of the road to Western Australia, convinced that state's government in 1960 to seal the highway all the way to the South Australian boundary. South Australia began sealing its section of the road in tandem Adv. 1. in tandem - one behind the other; "ride tandem on a bicycle built for two"; "riding horses down the path in tandem"
, but the work was less critical to that state, so was given a lower priority. The sealing of the Western Australian section was planned to be completed in stages from Norseman, by the end of 1971. The long duration of the work was the result of Commonwealth refusal to fund the road, forcing the state to find the monies itself (Edmonds, 1997, 223).

From Norseman to Madura, the new sealed road was built alongside the original to allow both construction and traffic to operate unhindered unhindered

. Some curves were added between Madura and Eucla to reduce driver fatigue and boredom, and the Main Roads Department considered in retrospect that this policy would have improved the 90-mile (146km) straight from Balladonia to Caiguna (Main Roads Department, 1972, 4), which is claimed to be the longest straight sealed road in the world (Reardon, 1996, 82).

Between Balladonia and Madura six such quarries were eventually established, providing a total of 300 000 cubic yards [230 000 cubic metres] of crushed limestone for use as base. These quarries also produced sealing aggregate. Together with a seventh quarry between Madura and Eucla used only for this latter purpose, a total of 57 000 cubic yards [44 000 cubic metres] of sealing aggregate was produced. The bitumen for sealing was initially trucked in from Perth, in drums. With the development of road tankers, up to 4500 gallons [20 000 litres] could be delivered by each truck. A total of 2 100 000 gallons [9 500 000 litres] was used (Main Roads Department, 1972, 7-8 & 11).

Another limiting condition was the availability of water. Dams were considered, but tests proved them unworkable due to the porous limestone bedrock. Even if lined with polyethelene, the dams were of little use due to the low and unreliable rainfall, less than 250mm annually, and high evaporation rates exceeding 1500mm (Main Roads Department, 1972, 5; Reardon, 1996, 14). A total of 27 million gallons [123 million litres] of water was instead sourced from bores and underground caverns, despite salinity higher than normally used for construction (Main Roads Department, 1972, 5; Reardon, 1996, 84).

 water for the workforce was trucked in from Norseman, up to 300 000 gallons [1 360 000 litres] per year, and a total of 1 400 000 gallons [6 400 000 litres] (Main Roads Department, 1972, 9 & 11; Reardon, 1996, 84).

The workforce grew over the initial years to about 90 men when large scale work began in earnest in 1965-66, reaching a peak of 125. This does not include wives and children, some of whom lived alongside their men for several years out on the highway project. The Main Roads Department provided the labour and most equipment, although some plant was hired. Part of this hired plant included mobile crushing units sourced from the Ready Mixed Concrete Co (the Readymix Group (WA) Ltd. from 1964).

Radio communication was maintained between the workgangs, their camps, and operational headquarters in Kalgoorlie. Motel-roadhouses were established at Balladonia, Caiguna, Madura, Cocklebiddy and Eucla during the project. (1) The John Eyre Motel at Caiguna was constructed in 1962, for example. These were the only sources of entertainment for the men, apart from a movie projector provided along with the mobile kitchens and ablution blocks for the construction camps. Air strips were constructed at each of the camps for pay runs, deliveries of urgent spare parts Spare parts, also referred to as Service Parts is a term used to indicate extra parts available and in proximity to the mechanical item, such as a automobile, boat, engine, for which they might be used.

Sealing to the South Australian boundary was completed ahead of target, on 17 October 1969 (see Table 1 & Figure 1), for a total cost of $9 645 000.2 On the South Australian side, the South Australian government sealed the highway from Port Augusta to Ceduna by 1968. This was extended to Penong in the early 1970s, leaving 266 miles (428km) to the border, which was completed on 29 September 1976 (Edmonds, 1997, 450). On the South Australian side the road was significantly rerouted in places, particularly between Nullarbor homestead and the border, where it was diverted to hug the scenic coast.


With the Eyre Highway fully sealed, annual daily average traffic volumes rose from 150 vehicles in 1969 to 250 in 1976, though as high as 800 per day during the Christmas period that year (Uren & Parrick, 1976, 28). The current annual daily average is 700 vehicles per day. Demonstrating how effectively the sealed road now competes with the railway, 45% of Eyre Highway traffic is heavy transport (DOTARS, 2003).


Readymix Ltd had been founded in Sydney in 1939 as the Ready Mixed Concrete Co., expanding into quarrying in 1957 with the purchase of Australian Blue Metal (ABM ABM: see guided missile.

ABM - Asynchronous Balanced Mode
) Ltd. In 1964, the Colonial Sugar Refining Co (after 1973 CSR (1) (Customer Service Representative) A person who handles a customer's request regarding a bill, account changes or service or merchandise ordered. Agents in call centers are known as CSRs. See call center.  Ltd) bought a half share in Readymix, as part of its own expansion into building products. In 1981 CSR acquired the remaining 50% of Readymix, and merged its quarrying and concrete operations to form Readymix-Farley. This was renamed CSR-Readymix in 1988 (Grolier, 1977; Readymix, c.2002). On 11 April 2003, a shareholder-approved demerger demerger n (Comm) → Abspaltung f, Demerger m  was effected, with CSR split into two groups, CSR Ltd and Rinker Ltd, with Readymix falling to the latter (CSR Ltd, 2003).

Readymix won each annual tender by the Main Roads Department of Western Australia to undertake quarrying operations along the Eyre Highway during its sealing, beginning at Balladonia in July 1964. About 1965, (3) probably in winter (Hoare, 2003), a decision was made to construct a giant rendition of the Readymix company logo virtually exactly halfway along the Eyre Highway, north of the 225 mile peg. One of the quarry surveyors was given the task of marking the logo out, and Allan Hoare, (4) a grader driver, graded it into the plain over a holiday weekend (Hoare, 2003; Hovingh, 2003; Keeris 2003; Kenny, 2003). The grader easily cut through the few inches of soil, revealing the white limestone bedrock underneath. The absence of trees or large rocks obviated any need for bulldozing prior to grading, or rolling afterwards (Green, 2003; Tarling, 2003b). (5)

In fact, the July 1967 issue of Readymix (WA) Ltd.'s company newsletter, Readymix Report, reproduced on its front page a photo taken out of an aircraft window, the logo appearing very clear and beautifully proportioned, against the natural landscape. Already it was "a subject of particular interest to the 400 airways passengers who, on average, fly daily across Australia to and from Perth" (Readymix Report, 1967) (8).

The diamond was soon recognised as the largest advertising sign in Australia, if not the world (Readymix Report, 1967).

In 1988 the entry was grammatically corrected to "Largest Letters", and "These were constructed ...", and the word "Nullarbor" was qualified by the addition of "Plain". However Guinness never corrected the erroneous date, despite the error being known to Readymix (for example Lindsay, 1978). Intriguingly, the entry in a 1970s Norwegian edition of the Guinness Book gives the date as December 1967 (Readymix Report, 1980), although this is still incorrect.

While the diamond was maintained by "occasional grading" from soon after its creation (DLS DLS

 (for example see CAF CAF - constant applicative form  8690, 1975). Some company executives viewing it while flying to Perth noted its deteriorating state (Green, 2003). Jimmy Merrick, a grading contractor and former Main Roads employee who had worked on maintaining the Eyre Highway in the 1960s, was initially asked to do it, but by then he was based in Esperance, and so declined (Merrick, 2003).

, owner of Balladonia station, was subsequently employed, and regraded it several times until about 1980 (Crocker, 2003; Green, 2003). Crocker took several days to do the job each time. His grader had a 12 foot [3.7m] blade, which when angled for grading made an 8-foot [2.4m] wide cut. The diamond's edges required 10-12 cuts and the letters required five. This suggests the diamond's edges were 24-29m wide, requiring 70-85 km of grading, and that the letter strokes were 12m wide (Crocker, 2003). Green (2003) estimated 90 miles (145 km) of grading was involved, but this may include the letters as well.

The maintenance grading was initially permitted by the MacLachlan family, who first became aware of the logo when their sheep musterers stumbled across it (MacLachlan, 2003). But permission was revoked about 1980 (Crocker, 2003; MacLachlan 2003). This withdrawal of permission was due to the regrading "further exacerbating terrible degrading created by Main Roads on both sides of the highway" (MacLachlan, 2003).

Once more the diamond began to fade. Increases in aircraft size, coupled with modern navigational technology, allow aircraft now to fly direct to Perth from the eastern states, across the Great Australian Bight, no longer needing to remain over land for navigation purposes.

 the logo, and it was left to deteriorate unseen, except for occasional scenic joyflights over it offered by the John Eyre motel (Across Australia ..., 1990, 98). By 1998, the diamond was barely visible, and the letters all but overgrown (eg see WA 4074, 1998). Even the Guinness Book of Records lost interest. The category of "Largest letters" last appeared in the thirty-seventh "1991" edition (Guinness, 1990), Readymix still holding the title.

Some misunderstanding and controversy has developed around the logo over the years.

The first claim is that the diamond was concreted, and even painted:
   R was for Readymix, a concrete company.
   Back in December 1971, some bored
   surveyors on the remote Nullarbor Plain in
   Western Australia, decided to survey letters
   spelling out their employer's name,
   READYMIX. These letters were dug into
   the desert, filled with concrete and painted
   white. So large are these letters that they can
   be driven on like roads. The letters now
   have a practical use--as a navigational
   device by pilots flying over the otherwise
   bleak landscape. The only way I could
   obtain a photograph of this incredible
   typographic phenomena [sic] was from the
   Australian satellite mapping bureau. How
   quickly the typographical can become
   topographical. (Banham, 1996, 50)

However, such claims are purely the result of misinterpretation of the aerial photo that Banham (1996, 51) reproduced. The "white-painted concrete" is actually the limestone base of the Nullarbor stripped clear of its covering soil. Banham's date, presumably obtained from the Guinness Book (1972, 86), is also wrong as has been shown above.

More significantly, there has been some controversy over the purpose of the logo. The accepted explanation of the logo is that is was an emergency airstrip. However, there have been suggestions that it was nothing more than a giant advertising sign. The evidence for each of these explanations will be examined in turn.

Emergency airstrip?

A number of current and former Readymix staff have independently explained the diamond as an emergency airstrip (eg. Cross, 1999 & 2003; Green, 2003; McIlhagga, 2003; O'Callaghan, 2003 a-d). But what documentary evidence is there?

A wall-map-sized enlargement of the 1967 vertical aerial photo of the diamond, framed and mounted in Readymix's Perth office, has a plaque reading:
   Diamond in the desert

   This 4-way Airstrip of individual design is
   in the Nullarbor Desert near the W.A.-S.A.
   border. It was put down by Readymix for
   forward use in quarrying aggregate for the
   Eyre highway and ballast for the
   Transcontinental Railway. An airline
   landmark, the airstrip makes the largest sign
   in the world, measuring two miles by one
   mile with letters 600ft. in depth. This
   photograph was taken from 31,000ft.
   (Readymix, n.d.)

While the photo can be dated, the plaque cannot, although it is likely to be from the late 60s or early 70s. The first dateable description, then, of the logo as an airstrip appeared in the July 1967 issue of Readymix Report:
   Australiawide [sic] interest has developed in
   a Readymix forward operations airstrip on
   the Nullarbor Plain in the form of the
   Group's traditional motif.

   A departure from the usual X-type
   emergency landing ground, the strip was put
   down as a faithful replica of the familiar
   Readymix sign.

   It forms the largest advertisement in
   Australia and probably the largest in the
   world. The horizontal points of the diamond
   are two miles apart while the letters forming
   the word Readymix are 800ft. long by
   600ft. wide.

   The strip was simply bulldozed into the
   Nullarbor scrub slightly north of the
   transcontinental Eyre Highway 183 miles
   east of Norseman. It services remote Group
   operations of quarrying in that area to
   supply road surfacing materials used in
   sealing the highway.

   Ansett-ANA and TAA Boeing 727 captains
   report the diamond and its lettering to be
   clearly visible from 35,000 ft. and a subject
   of particular interest to the 400 airways

   Australia to and from Perth. (Readymix
   Report, 1967, 1)

More details of the reason for the airstrip's construction emerged once the Western Australian Department of Lands and Surveys (DLS, now the Department of Land Administration: DOLA) became aware of the diamond. According to according to

2. In keeping with: according to instructions.

 one account, Noel Semmens, Western Australian Branch Manager of Mobil in the late 1960s (see Mobil News, 1970, 8), saw the logo soon after it was constructed, while flying to Perth. He contacted the DLS to obtain permission to construct a giant Mobil logo, similarly under the domestic flight-paths to Perth. The Department knocked him back, not wanting to turn the Nullarbor into a billboard. Semmens asked how Readymix had gotten permission, and suddenly the DLS wanted to know too (O'Callaghan, 2003a). On 29 June 1970, the Under Secretary for Lands wrote to "The Manager, Readymix":
   My attention has been drawn to the fact that
   vegetation has been cleared from
   Nightshade Station, approximately 560 air
   miles east of Perth, on Crown land.

   The clearing takes the form of a large diamond
   with the word "Readymix" in the centre and is
   being maintained by occasional grading.

   Will you please advise by whose authority
   the sign was created. (DOLA, 1456/70)

The General Manger of Readymix (WA) Ltd., Eugene O'Callaghan Reverend Dr. Eugene O'Callaghan (born 7 January 1888 at Camlough) was a priest in the Diocese of Clogher, ordained on 21 June, 1913. He was appointed the Roman Catholic Bishop of Clogher in Ireland on 30 January 1943, following the death of his predecessor, Dr. , replied on 16 July:
   We acknowledge your letter of the 29th
   June, reference 1456/70, in which you refer
   to an emergency light aircraft landing strip
   which was constructed by our company
   some 4 to 5 years ago.

   At about that time our company had been
   continuously engaged in the fulfilment of a
   series of quarrying contracts for the Main
   Roads Department related to the
   construction of the Eyre highway,
   commencing at Balladonia in July 1964 and
   completing at Eucla in May 1967. During
   the whole of the progress of these works the
   various project sites were serviced using a
   range of chartered light aircraft, the size of
   which on any particular occasion depended
   on the nature of the individual need. (11)

   Initially, having been invited to use various
   light aircraft landing strips available along
   the route, it became apparent that these were
   not to a standard in conformance with our
   insurance requirements. Subsequently
   similar "X" shaped strips were constructed
   by ourselves. However, as these were not
   readily distinguishable from other unreliable
   strips, it was resolved that a clearly
   identifiable emergency landing strip in the
   form of a diamond should be constructed in
   such a manner that it could be reliably
   called upon for use in any circumstance
   when our aircraft, caught by unfavourable
   weather conditions due to a lack of weather
   reports in this remote area, would be able to
   safely land in the area. The particular
   urgency for this arose when as the result of
   two occasions of severe unseasonable and
   unforecast weather it became necessary to
   obtain D.C.A. [Department of Civil
   Aviation] and M.R.D. [Main Roads
   Department, Western Australia] approval to
   land on the Eyre Highway--with the
   removal of guide posts and need for road
   closing protection, etc.

   The consequence of establishing this strip
   permitted the completion of the project,
   involving 7 quarry locations and
   approximately 500,000 c.yds. of road
   construction materials, without further
   incidents of concern or danger to aircraft
   operating safely. (DOLA, 1456/70)

Other groups besides the DLS became aware of the diamond about the same time. On 2 December 1970, the Western Australian branch of the National Trust of Australia The National Trust of Australia is a community-based, non-government organisation, committed to promoting and conserving Australia's indigenous, natural and historic heritage through its advocacy work and its custodianship of heritage places and objects.  wrote to the DLS:
   I have been requested by the Council of the
   National Trust to write to you on the subject
   of the sign which the Readymix Group
   (W.A.) appear to have bulldozed in the
   Nullarbor Plain.

   Council feel that while there is no objection to
   this one sign, it would be unfortunate if the
   practice became general. Council, of course, is
   not aware if approval was given for this sign,
   but I am to request that consideration be given
   to preventing the making of any other such
   signs. (DOLA, 1456/70)

The DLS replied on 9 December, enclosing O'Callaghan's explanation of the logo:
   In connection with your letter of the 2nd
   December I attach copy of a letter from
   "Readymix" dated 16th July 1970 which will
   explain the circumstances under which the
   Readymix sign was bulldozed in the Nullarbor
   Plain without approval from this Office.

   In a discussion with the Manager of the
   firm, it was agreed that although the
   diamond shape could remain as a landing
   strip, the word "Readymix" would not be

   I am unaware of any other signs and it is
   most unlikely that any applications will be
   approved unless they are for bona fide
   landing strips. (DOLA, 1456/70)

Strangely, the DLS made no mention of Noel Semmens' idea for a Mobil logo in this letter.

They are produced at a scale of 1:1,000,000 (approximately 1 inch = 13.  (WACs). Readymix obtained precise information from DLS, and forwarded it on (O'Callaghan, 1971a-c). Interestingly, while these Readymix letters all refer to the "diamond in the desert emergency landing strip" or "emergency airstrip", and despite the supposed urgency of the DCA's request, the diamond has only ever been depicted on WACs as a landmark. It has never been recorded on any aeronautical charts or other maps as an airstrip, whether disused disused

 desk contacted Readymix's head office in Sydney about the diamond. He wanted colour slides of it for a "big Japanese colour TV show Children of the World" (Sherman, 1978). It is not clear whether this was a request from the TV show via the AIS, or direct from AIS itself. The request was passed to Clive Lindsay (13), Readymix's safety manager in Perth, who, through DLS, supplied an 18-inch enlargement of the 1967 aerial photo and the 1967 Readymix Report article. Lindsay's covering letter, besides mentioning that the logo was an airstrip, noted that the Guinness Book date of 1971 was wrong, and gave a correction of 1964. He also enclosed "a 6-inch x 8-inch Black and White print of aerial photograph 3661-1" (Lindsay, 1978), of which I have been unable to trace any further information.

TAA's in-flight magazine Transair published a small feature on the diamond in December 1979, along with the ubiquitous 1967 aerial photo:
   Desert diamond

   Passengers on TAA flights to Perth will
   probably recognise the Readymix symbol in
   this photograph (above).

   The Readymix diamond-shaped symbol is part
   of a disused emergency airstrip on the Nullarbor
   Plain, 800km east of Perth, on the western side
   of the Great Australian Bight and close by the
   major air routes followed by TAA.

   It is probably the largest corporate symbol
   ever displayed by a company, measuring
   3.2 km by 1.6 km. Each letter of Readymix
   is 262 m by 196 m.

   Origin of the diamond goes back to the
   sealing of the Eyre Highway No. 1 in 1967.
   Readymix performed contract work on the
   remote section between Balladonia and
   Eucla. Eight campsites were necessary, each
   with its own airstrip.

   It was possible to identify each camp by the
   shape of its airstrip, and the diamond shape
   of the emergency "between" strip was
   commissioned as an interesting variation on
   conventional design.

 was reproduced in the Summer 1980 edition of the Readymix Report, which once again featured the diamond:
   Spreading the Word

   They say a picture is worth a thousand
   words ...

   The diamond shaped Readymix symbol
   shown in the photograph was bulldozed out
   of barren earth on the Nullarbor plain near
   Balladonia, 800km east of Perth, in the
   1960s--for use as an airstrip!

   At the time, Readymix was engaged in a
   series of quarrying contracts related to the
   construction of the Eyre Highway between
   Balladonia and Eucla. The variouse [sic]
   project sites were serviced by light aircraft
   and it soon became apparent that the existing
   X-shaped landing strips were below standard.

   It was decided to construct a clearly
   identifiable airstrip which could be used
   with confidence. The diamond-shaped
   design was commissioned as an interesting
   variation to a convention theme.

   The message for pilots was loud and clear--and
   so it should have been. The symbol
   measures 3.2km (2 miles) across its
   horizontal axis and 1.6km (1 mile) across
   the vertical axis.

   The Readymix diamond in the desert is still
   an acknowledged landmark in Australian
   aviation today, as shown by the recent
   extract from T.A.A.'s December 1979 issue
   of "Transair" magazine.

   And talk about spreading the word. The
   symbol has found its way into the Guinness
   Book of Records, including its Norwegian

   The entry reproduced below was recently
   shown to a Readymix couple holidaying in
   Norway. A teenage son of the host family
   quickly produced the article in their
   Guinness book when he learned that their
   guest worked at Readymix in Western
   Australia (Readymix Report, 1980).

Also included was the Norwegian Guinness Book entry, and a translation, although the incorrect logo-creation date of December 1967 was neither corrected nor commented on.

It is perhaps not coincidental that this was the last story of the diamond in print, in the same year that permission to maintain the diamond was withdrawn. The diamond has therefore slowly faded from both memory and the Nullarbor ever since.

Not an airstrip?

The evidence for any other explanation of the diamond is sparse, mainly negative in character, and so highly circumstantial.

The most explicit, and the only real documentary evidence, comes from Readymix itself. While stories in the 1967 and 1980 issues of the Readymix Report clearly note that the diamond was an airstrip first, and an advertisement second, these were not the only time the diamond featured in the company's newsletter. In between, in 1978, the second Readymix Report to mention the diamond not only failed to mention its airstrip origin, but almost explicitly suggested it was no such thing. The central four pages of the December 1978 issue were a Report on Mobile Quarry Operations, and ended with the 1967 aerial photo of the diamond, captioned "After hours Adv. 1. after hours - not during regular hours; "he often worked after hours"  activities on mobile units are few, but one crew in the Nullabor [sic] produced this gigantic Readymix diamond". The associated blurb read:
   The big demand [sic!!]

   As a lasting reminder to [sic] the part played
   by the mobile crews, the Nullabor [sic] Plain
   carries a unique company advertisement. One
   mobile quarry plant was established on the
   Nullabor [sic] desert plain hundreds of miles
   from anywhere right on the former air-route
   between Perth and Adelaide.

   The quarry team found the desert top soil
   carrying the coarse spinifex grass is a dusty
   brown sand, only a few inches deep with white
   limestone beneath it. So as an after-hours
   exercise the surveyor calculated dimensions
   and angles for a giant-size company diamond
   symbol about two miles long and one mile
   wide, each letter being 180m tall. The
   workmen then bulldozed and graded out the
   brown surface sand to produce a giant famous
   'Readymix' company trademark in brilliant
   white limestone, helping to relieve the
   monotony of the flat scenery viewed by the
   airlines' passengers, and provide Readymix
   with an entry in the Guinness Book of Records
   as the largest advertising sign in the world.
   (Readymix Report, 1978)

Banham's brief discussion of the letters also attributes the logo to "bored surveyors" (Banham, 1996, 50), as does the Western Australian Tourist Centre (Hull, 1999). Such an explanation has been supported by former Readymix quarry division manager Bill Fox, who claims to have come up with the whole idea of the diamond, without reference to headquarters in Perth. The logo, large enough that it would fill the standard thirteen-inch [33cm] window of passing passenger aircraft, was built both to keep Fox's men busy during a delay in work on the Eyre Highway, and for advertising (Fox, 2003a,c).

Further, a number of sources contacted had never heard that the logo was an airstrip, and had always assumed it was carved purely for advertising purposes (eg Crocker, 2003; Hoare, 2003; Kennedy, 2003; MacLachlan, 2003; Tarling, 2003b).

The inordinate distance of the diamond from both the Eyre Highway and Readymix's quarries is highly peculiar, especially since the only access to the diamond appears to have been an unformed vehicle track, which was difficult to travel on in the wet (Hoare, 2003). Together with the facts that the diamond has never appeared on any charts as an airstrip, and was only graded and not rolled, this does not sit well with an explanation of the diamond as an airstrip built because existing strips were not up to insurance standards (14).


The suggestion that the logo might not have been an airstrip has been rejected both by Readymix (WA) Ltd.'s current staff, and by its former regional manager (Cross, 1999 & 2003; O'Callaghan, 2003a,b&d). O'Callaghan himself (2003a&b) disproves the suggestion stating that he was present on a company aircraft, flying from Kalgoorlie to inspect the highway work, which was forced by bad weather to make a choice whether to land on the existing clay strips rendered dangerous by the weather, to make an emergency landing on the highway, or to turn back. Therefore he himself ordered the construction of the emergency strip for reasons of safety and efficiency.

Two explanations have been offered for the apparently anomalously large size of the diamond compared to other airstrips along the Eyre Highway. First, that the original instructions original instructions (ō·riˑ·j·n  from headquarters in Perth called for a diamond-shaped strip of standard proportions (1km legs), and that Fox, or other staff on site, decided that it would require little extra effort to make the diamond twice as large for advertising or other reasons. This could explain competing claims to ownership of the idea. Second, that Perth headquarters themselves decided to increase the size of the diamond, so that it could be used not only by their own small aircraft, but even by even larger private aircraft if necessary. Whatever the explanation for the diamond's size, O'Callaghan agreed that the lettering inside the diamond was Fox's idea, and was useful not only as advertising but also to increase the visibility of the airstrip for pilots, whether needing to use the strip, or just overflying it and using it for locational purposes (O'Callaghan, 2003a-d).

That people directly involved with the logo like Crocker (2003) and MacLachlan (2003) were unaware of its airstrip origin might also be explained. O'Callaghan admits that the diamond was probably never used for emergency landings, although its presence at least provided greater peace of mind both to Readymix's pilots and executives (O'Callagan, 2003a-d) (15). After the completion of the sealing of the Eyre Highway on the Western Australian side in 1969, the diamond would no longer have been needed as an airstrip, and subsequent maintenance appears to have been solely to retain its advertising and aerial landmark functions. This could explain why Crocker was unaware of any original airstrip function. For MacLachlan the explanation is probably similar, particularly if it took several years for his pastoral company to become aware of the presence of the diamond.

If the airstrip utility of the diamond was only temporarily necessary and never actually required, and the logo was maintained for alternative reasons in the 1970s, this could also account for the fact that the diamond has never been shown on aeronautical charts and other maps as anything but an aerial landmark.

Another problem with the airstrip explanation is the diamond's distance from the road. O'Callaghan (2003b) suggests that this was due to the distance of the nearest limestone outcrop into which the diamond could be easily graded. Yet unless there is a significant difference in the soil depth between Caiguna and the diamond, which appears highly unlikely given the geology and topography, this suggestion is not borne out by geological survey The term geological survey can be used to describe both the conduct of a survey for geological purposes and an institution holding geological information.

If Readymix (or Readymix employees without head office's knowledge) had created the diamond purely for advertising purposes or out of boredom, then it is possible that a myth was created to cover this up and that it has persisted for more than 40 years. Given that all staff involved at the time have now retired, one can speculate that the airstrip explanation, if created as a cover-up, has come to be accepted by current staff as the actual explanation.

However, to dismiss the airstrip explanation as a myth, would mean belying not only the documentary evidence, but also the accounts of a number of former and present staff. As there is so little evidence in the other direction, this would seem untenable. Given that the diamond was carved nearly forty years ago, it is not surprising that memories of those involved do not tally exactly, and intriguing discrepancies exist.


Whether or not the giant Readymix logo was carved for use as an emergency airstrip, it certainly appears it was never required as one. It was, however, aeronautically utilitarian in other ways, as a visible and recognisable aerial landmark on the otherwise featureless Nullarbor, particularly for about 15-20 years when commercial airliners still flew overland to Perth. The lettering inside the diamond also provided an important secondary advertising function. With the rerouting of airliners over the Great Australian Bight as a result of improvements in aircraft and navigation technologies, both of these functions declined, and the diamond was left visible only to occasional light aircraft. Together with a prohibition on further maintenance, the logo became overgrown, and today is only barely visible from the air, although it still survives on a number of maps, including some issued very recently.

Carved c.1965, the Readymix diamond on the Nullarbor may possibly have been no more than a giant corporate graffito graffito (gräf-fē`tō).

While documented by aerial photos as early as 1967, the diamond first appeared on maps only from the early 1970s. It continues to do so, not only on aeronautical charts, but also topographic maps, roadmaps and tourist maps, despite now being virtually totally overgrown. All known vertical aerial photos, atlases, aeronautical charts and maps depicting the diamond are given below, along with information on earlier editions not showing it.

(8) The Readymix logo's simple shape had been used before for aerial identification. Green (2003) recalls as mobile quarry manager setting up the prefab huts at mobile quarry camps in formation, facing in on a central diamond of land, which would be cleared, and red loam loam, soil composed of sand, silt, clay, and organic matter in evenly mixed particles of various sizes. More fertile than sandy soils, loam is not stiff and tenacious like clay soils.

An aerial photo of such a camp can be seen in Readymix Report (1978, 4).

(9) Green (2003) used to possess the original scale plan used to peg out the diamond, but has since lost it.

The first titleholder was "... a gigantic letter 'L', made in 1927 on a hillside behind La Verne La Verne (lə vûrn), city (1990 pop. 30,897), Los Angeles co., S Calif., a suburb of Los Angeles; inc. 1906.

It is 340 feet high and 45 feet wide". This survived to the 13th edition of Oct. 1966. It was replaced in the 14th edition of Oct. 1967 by "... the giant 'W' on the north side of Mount Tenderfoot Tenderfoot

It is the county seat of Gunnison CountyGR6. The city was named after John W. , U.S.A. The 'W' was made with flat stones on 2 May 1923, when it measured 400 feet high and 300 feet wide, with 'legs' 16 feet wide. In c.1932 the size of the 'W' was increased to 420 feet high and 320 feet wide, making a total area of 25,560 square feet of rock". This entry survived until and including the 18th edition of Oct. 1971 (Guinness, 1956, 1960, 1966, 1967 & 1971).

(11) Readymix apparently owned its own twin-engined Aero 145, a Czech aircraft, and had long-term charters of various Cessna 185, 310, and 400 models for crew changes (Fox, 2003a).

(12) Only one map, the third edition of the Traveller's Atlas of Western Australia (DLS, 1986) shows an airstrip in the general location of the logo. However, this possible evidence for the airstrip explanation is coincidental. The supposed strip was not shown in the two earlier editions (DLS, 1978 & 1982), when the logo may have been more likely to be useable as a strip due to its concurrent maintenance by Crocker. The first edition shows only the John Eyre Motel on the south side of the highway and the microwave tower to the north. These are shown in their correct location, and named. Additionally, immediately west of the locality is a trapezium trapezium /tra·pe·zi·um/ (-um) [L.]

Contraction serves the same purpose but is understood strictly to be the shortening of a word by cutting out letters in the middle,  for the locality used on road distance markers. The second edition adds two more informational symbols: a red-outlined letter 'R' and a similar letter 'A', indicating the presence of a roadhouse and accommodation at Caiguna. Both of these are placed above the correctly-located microwave tower symbol, leaving a small gap between them and the trapezium. In the third edition, this gap is filled with a landing ground symbol. It is entirely coincidental that the symbol is shown north of the Highway in the same direction from Caiguna as the Readymix diamond. The symbol in this case is indicative, not positional, and only denotes the presence of an airstrip at Caiguna, namely the one behind the John Eyre motel immediately south of the Highway. It has been placed as close to Caiguna as possible in a gap between symbols already existing rather than locating it correctly which would then obscure the detailed depiction and naming of various rock holes south of the highway on the original base map. Finally, while the airstrip symbol is shown in the same direction from Caiguna as the Readymix logo, it is only half the correct distance out, about 6 km instead of about 13km.

(13) Lindsay was called upon again in 1981 when Peter Winner of the West Australian newspaper phoned to obtain information on the diamond for an article ('Rita', 1981). Contact with Winner and the West Australian's library suggest the article was almost certainly never written (Bennett, 2003; Winner, 2003).

(14) While Crocker (2003) and Fox (2003a&c) maintain that the surface was too rough for aircraft, O'Callaghan (2003d) says that the Readymix pilot's own specification for making a serviceable emergency strip was "drag a heavy beam for 1km & then test for vehicle satisfaction at 90kmh.... If it can accept 90kmh adequately smooth travel over the finished surface ... that was the criteria."

(15) There are claims aircraft unable to use the standard strips continued to land on the Eyre Highway if necessary (Fox, 2003a&c) as there was little traffic, parts were already sealed, and the highway was the worksite to which the aircraft were heading, unlike the diamond which was 7km away from the road.

(16) The largest figures at Nazca are almost 300m long, the lines up to 20km. In an ironic parallel, and at the same time that the Readymix airstrip story first appeared, von Daniken (1969, 30-2) famously suggested that the Nazca lines were landing strips for alien spacecraft An alien spacecraft is a hypothetical spacecraft originating from extraterrestrials. Alien spacecraft are often featured in science fiction. Many UFO sightings have been speculated to be alien spacecraft by their viewers. , although this had been suggested in jest for mere sport or diversion; not in truth and reality; not in earnest.
