On 30 August 2004, John Anderson issued two Directions to Airservices
Australia. One requires Airservices Australia to establish and operate radar at
a number of additional airports. The cost of the establishment of these radar is
estimated to be $150 million.
Section 16 of the Air Services Act states that costs incurred by Airservices
Australia, if greater than would otherwise have been incurred as a result of
Directions from the Minister, must be paid for by the Commonwealth.
