The administration and management approaches adopted by the three active states differ slightly. In New South Wales, the Roads and Traffic Authority (RTA) has over- sight of its highway system as well as its PPP program. In Victoria, the state has created temporary public authorities for the sole purpose of managing the procurement of its highway PPP projects. Once operational, the public authorities are disbanded and the responsibility for contract administration and management is handled by VicRoads, the state's highway agency. In Queensland, the state has followed the model in Victoria for the procure- ment of AirportLink, creating an independent authority for this purpose. The state's Department of Main Roads will ultimately assume responsibility for its contract management.
