Business Editors/High-Tech Writers

LOS ANGELES--(BUSINESS WIRE)--June 4, 2001

Advanced Communications Technologies Inc. (OTCBB:ADVC) (ACT-US) today announced that one of its Australian-based affiliates, Australon Limited (ASX:AUR) has successfully demonstrated its wireless remote automated meter reading (AMR) technology in a real time field trial environment.

The AMR technology is currently being demonstrated in a field trial in the inner-Melbourne suburb of Richmond, Victoria. The trial has successfully transmitted AMR data, taken at 15 minutes intervals, back to a network operations centre located in the Melbourne CBD. In addition, the trial has also allowed for the successful collection of valuable Demand Side Management (DSM) information and demonstrated the technology's Remote Connect/Disconnect (RCD) functionality for turning power on and off at specific locations.

The success of this trial is an important milestone in validating the Australon AMR technology in a real-world environment. As previously announced, the Company plans that a larger scale trial of the Australon AMR technology will be undertaken in conjunction with a major utility in the coming months. It is expected that successful completion of the trial will lead to a full-scale roll out of the AMR technology across the utility's customer base of one million homes. Australon is currently negotiating with several utilities across Australia representing a customer base of four and a half million homes.

"The crippling rolling blackouts in California are a prime example of the need for the real time demand side management capabilities offered by Australon's AMR technology," said Roger May, Chairman of ACT-US. "We believe that the AMR unit's ability to actively monitor loadings would enable utilities to shut down items selectively leaving the majority of users free to enjoy uninterrupted power supply. With the successful implementation of this trial we now have a demonstrably successful example of Australon's leading edge AMR technology that can be demonstrated to any utility in the world from any location in the world via the internet. This ability to definitively demonstrate the cost and time saving advantages of the AMR technology should prove a powerful tool in generating revenues and we believe it will lead to a dramatic increase in interest in the Australon AMR technology by power utilities around the world."

One of the most significant advantages of the Australon AMR technology is that it can be installed in the home for a total cost of $A150, inclusive of equipment and installation.
