You can request a change to how Australian-administered airspace is managed by submitting an Airspace Change Proposal (ACP).
An ACP is a request to change how we manage airspace. It can:
- suggest an airspace solution
- describe an operational problem
- request an amendment
- declare an activity that could be an airspace risk.
If you would like to suggest a change, you can submit an ACP.
Who can submit an ACP
Anyone can submit an ACP including:
- airspace users
- aerodrome operators
- government partners such as Defence and Airservices Australia.
Who decides on ACPs
We are responsible for approving or rejecting an ACP. Airservices Australia decides where air routes go and submits ACPs to implement route changes. We include noise assessments as part of flight path and route planning.

After you submit an ACP
-
Initial review
We check that your ACP has enough information and supporting analysis for us to assess it. We look at:
- safety
- efficiency
- fair access to airspace
- costs
- national security
- if the change is realistic and achievable.
We will also check if the proposed start date allows enough time for:
- processing
- analysis
- further stakeholder consultation.
We will tell you if the ACP has enough information or if we need more.
-
Safety and risk review
We check if your ACP includes the required safety documents. At a minimum, this must include a risk assessment.
For larger or more complex proposals, we ensure the risk assessment suits the size and complexity of the activity. We consider:
- airspace users
- traffic levels
- weather
- terrain
- other relevant factors.
We also check:
- the current operating environment
- key safety issues
- the potential impact of the proposed change.
We then review your safety case to determine whether any remaining safety risk exists for airspace users.
-
Stakeholder consultation review
We review evidence that you have consulted stakeholders. If needed, we may carry out further consultation or ask you to do more.
-
Environmental considerations
-
Cost impacts
For major changes, we include a Regulatory Impact Statement. This shows the cost impacts for all airspace users.
-
Compliance and documentation
We check the ACP against current legislation, policy and procedures. If we approve the ACP, we prepare the legal and aeronautical documents needed to bring it into effect.
-
Outcome
We will notify you if we approve your ACP or not.
