TSA is providing services on behalf of Airservices during the requirements definition, planning, design and delivery phases of the OneSKY infrastructure program. The program comprises new equipment rooms and new/upgraded air traffic service centres at Melbourne, Brisbane and Perth airports.

These projects will enable the installation and operation of the new civil-military air traffic system (CMATS), a joint solution between Airservices and Defence providing a single harmonised air traffic management system. The new system will deliver the most advanced and integrated air traffic control system in the world.
