What is OneSKY?

OneSKY Australia™ is the most complex transformation of air traffic management in Australian aviation history. It’s a partnership between Airservices and the Department of Defence, replacing existing air traffic management systems with an advanced integrated system known as the Civil Military Air Traffic Management System (CMATS). OneSKY Australia™ was established to deliver more efficient air services, support future air traffic growth and enhance national security. The program will deliver more than $1.2 billion of economic benefits to Australian airspace users over 20 years.

Shaping the industry

Next generation technology

Airservices is delivering six advanced technology initiatives under the OneSKY Australia™ Program, harmonising Australia’s civil and military air traffic management into one seamless system that’s built to enhance the safety, efficiency and capacity of the Australian air traffic network.

Purpose built

World-class infrastructure

OneSKY is delivering purpose-built Airservices buildings to house and support CMATS and its associated operations room as Airservices transitions to the new system.

As the existing system must be maintained until CMATS is operational, establishing an alternate facility with independent systems ensures a seamless transition for airspace users without interruption to services.
