Airservices is Australia's air navigation service provider - we provide air traffic control, aviation rescue and fire fighting and air navigation services.

Airspace Modernisation

As part of Airservices commitment to fostering and promoting civil aviation, a number of airspace modernisation initiatives will be implemented over the next five years to enhance the efficiency of controlled airspace in Australia, while ensuring and maintaining current levels of safety.

Three changes currently proposed are:

  • National Standardisation of Class A and E Airspace
  • Transfer of control responsibility of surveilled Class C airspace from Air Traffic Control Towers at five regional locations to an Enroute sector in either Melbourne or Brisbane Air Traffic Services Centres
  • Class E Airspace Trial at Ayers Rock from 5,500ft (AMSL)

This page will be regularly updated as progress continues on these initiatives.

The formal consultation period for these changes has now closed and Airservices is reviewing all feedback received regarding these changes. If you have any further questions regarding these changes, please email

National Standardisation of Class A and E Airspace

The first proposed change is the national standardisation of Class A and Class E airspace over continental Australia. Airservices is proposing changes to the continental, low, medium and high density airspace. This will help standardise Australian airspace and deliver increased service consistency to all airspace users. Most importantly, it will enhance the safety and efficiency of operations in these areas.

This will allow VFR aircraft access to an increased amount of airspace that was previously not available to them to enter.

Subject to approval by the Civil Aviation Safety Authority (CASA), this proposed change will be implemented in November 2019, which will benefit airspace users operating in continental, low, medium and high density areas with a greater level of surveillance and service.

More information on this proposed change is available on the National Standardisation of Class A and E airspace fact sheet.

Transfer of Control Responsibility of Surveilled Class C Airspace from the air Traffic Control Tower to Enroute Controllers at five regional locations

We are transferring services for arrivals, departures and transit traffic provided at five regional Class D aerodromes through the change of control jurisdiction from the Air Traffic Control Towers at Tamworth, Alice Springs, Albury, Launceston and Hobart Towers to a surveillance enroute sector in either the Melbourne or Brisbane Air Traffic Services Centres.

Proposed for implementation in May 2019, this change will not affect the airspace classification of airspace, but will amend who is controlling airspace (transferring from the non-surveillance Air Traffic Control Tower to the surveillance Enroute controllers and lowering the upper limit of tower control from 8,500ft to 4,500ft).

This change in service provision responsibilities will remove some variations of regional Class D aerodrome airspace management and will provide standardisation and consistency across the country.

Trial of Class E Airspace at Ayers Rock

Airservices is proposing to trial the utilisation of Class E airspace above the existing Common Traffic Advisory Frequency (CTAF) from 5,500ft (AMSL) in the form of new Class E control area steps, replacing the current Class G airspace at Ayers Rock. It was initially planned to conduct this trial from 1,200ft (AGL), however after feedback was received from airspace users and stakeholders, the decision was made to change the airspace design to provide a better service to all airspace users of Ayers Rock.

Subject to approval from the Civil Aviation Safety Authority (CASA), the proposal will only affect Instrument Flight Rules (IFR) operating aircraft, allowing them to receive a surveillance based separation service from air traffic control.

There will no change to the existing Certified Air/Ground Radio Service (CA/GRS) and VFR aircraft operating in Ayers Rock will continue to self-separate.

More information on this proposed change, including the proposed airspace design and information on flight paths is available on the Trial of Class E Airspace at Ayers Rock fact sheet.
