Boorman took long road to Australia.
By Any Means for BBC2 saw him travel from his home town in Wicklow in Ireland to Sydney in three months.
He marked the final stage of the adventure by leading a motorcycle convoy of more than 300 bikers across Sydney's Harbour Bridge.
During filming, a three-man crew have used more than 100 different modes of transport.
The adventure will be made into a six-part TV series to be shown from September on BBC2, and on the National Geographic Channel globally next year.
The countries visited include Turkey, Georgia, Azerbaijan, Iran, India, Nepal and Indonesia, with forms of transport ranging from trains to container ships, dugout canoes, cement barges and solar-powered cars.
But 41-year-old Boorman ended the adventure on his favourite form of transport - the motorcycle.
The trip is a follow-up to the two epic motorcycle journeys he made with his friend, Scots actor Ewan McGregor.
These were the Long Way Round, which saw them travel around the world from London to New York via Europe and Asia, and, more recently, the Long Way Down from Scotland to South Africa.
