The protection of airspace is essential to provide a safe and predictable environment for the arrival and departure of aircraft using the airport. Any activity that will result in the intrusion of protected airspace, such as controlled activities, crane use, external lighting, balloons and unmanned aircraft (drones and rockets), requires approval before it can be carried out.
The Department of Infrastructure, Transport, Regional Development and Communications (DITRDC)
(Department) protects the airspace around leased Federal airports under the Airports Act 1996 and the Airports (Protection of Airspace) Regulations 1996. The protection of airspace is essential in order to provide a safe and predictable environment for the arrival and departure of aircraft using an airport.
International standards have been adopted which define two sets of invisible surfaces above the ground, these include:
1. Obstacle Limitation Surface (OLS): a defined area of airspace designed to provide protection for visual flying (VFR) operations, where the pilot is flying by sight. All existing and potential obstacles must be assessed to ensure that any impact on aircraft operations is identified.
2. Procedures for Air Navigation Services – Aircraft Operations (PANS-OPS): a defined area of airspace designed to provide protection for instrument flying (IFR), where the pilot is reliant on instrument navigation. PANS-OPS surfaces may also include protection of the airspace around navigation aids that are required for instrument flying activity. PANS-OPS surfaces are not permitted to be infringed in any circumstance.
Any activity that will result in an intrusion of protected airspace are referred to as controlled activities and must be approved before being carried out.
Controlled activities include:
How do you know you need an approval?
[Sourced from https://www.infrastructure.gov.au/aviation/safety/protection/leased.aspx#anc_8]
The activity you intend carrying out will generally require an approval by State or local government authorities. Larger projects may require an Environment Impact Statement while most projects will require the issue of a building permit by the local council.
Local councils in the vicinity of an airport's protected airspace are required to review all building and development applications they receive for any intrusions of protected airspace.
These local councils refer proposals to the airport operator if an intrusion is likely to occur. The proponent will then need to apply through the airport operator for approval.
Airport operators are required to make charts of the OLS and PANS-OPS surfaces available to the public. In most cases these charts are also incorporated into the local council's planning information databases. To avoid any doubt, applicants (e.g. developers, builders and crane operators) should check with the airport operator (or their local council) at the earliest possible stage. Moorabbin Airport can be contacted here.

How do you apply?
Applications to carry out a controlled activity are to be made to Moorabbin Airport Corporation (MAC) in writing as below.
- whether the activity results in an intrusion into the OLS or PANS-OPS surface
- the extent of the intrusion
- the precise location of the development or activity.

CASA has the authority, under the Civil Aviation Regulations 1988, to control ground lights where they have the potential to cause confusion or distraction (from glare) to pilots in the air. Ground lights may cause confusion or distraction by reason of their colour, position, pattern or intensity of light emission above the horizontal plane.
Regulations on lighting in the vicinity of aerodromes is located in the CASA Manual of Standards Part 139 – Aerodromes, Section 9.143, Other lighting on the aerodrome and provides guidance on the design and installation of lights in the vicinity of an aerodrome (within a 6km radius of an airport). It is the responsibility of the lighting designer to ensure that the lights meet the requirements prescribed in the Civil Aviation Regulations, Civil Aviation Safety Regulations and Manual of Standards Part 139. It is also the responsibility of the lighting supplier to meet National Airports Safeguarding Framework (NASF) Guideline E Managing the Risk of Distractions to Pilots from Lighting in the Vicinity of Airports (see link here).
How do you apply?
A pavement concession is required for the following:
If you are conducting a fireworks display, you will need to notify CASA and get an approval for the display. You will also need to contact your relevant council or state/territory authority to determine if other approvals are required. Further information on CASA fireworks approval can be found here.
Lasers/ Light Shows
Lasers and high-intensity lights like sky trackers, pose a serious risk to pilots which can result in difficulties flying and impaired vision. It takes only a fraction of a second to cause flash blindness or ocular damage, even if the aircraft is travelling quite quickly. Any person or organisation wishing to conduct a laser or high-intensity light show must notify CASA. Further information on laser and light shows can be found here.
Small balloons (<50 grams of payload) released in large bunches can pose a safety hazard to aircraft by distracting pilots or getting caught in engines and propellers.
It is a requirement under Civil Aviation Safety Regulation – 1998 (CASR) Regulation 101.E that the CASA approves the release of balloons into airspace surrounding an airport. CASA contacts can be found here.
Requirements for the release of small balloons (referenced from CASR 1998, Part 101.155)
|Number of balloons to be released at one time||Distance from place of release to nearest aerodrome
|Less than 3 nautical miles (5.5km)||3-6 nautical miles (5.5-11km)||6-12 nautical miles
|Over 12 nautical miles (22km)|
|101-1,000||CASA approval||NOTAM||No approval required||No approval required|
|1,001-10,000||CASA approval||CASA approval||NOTAM||No approval required|
|Over 10,000||CASA approval||CASA approval||CASA approval||NOTAM|
CASA approval - means that an approval under subregulation (5) is required for the release of that number of balloons at a place within that distance from the nearest aerodrome.
NOTAM - means that CASA’s approval is not required, but the person intending to release that number of balloons at a place that distance from the nearest aerodrome must give to CASA the information about the proposed release required by table 101.155 2.
No approval required - means that no such approval is required for the release of that number of balloons at a place within that distance from the nearest aerodrome.
Unmanned aircraft, such as drones and rockets, can pose a serious hazard to aircraft operators.
CASA are the controlling authority and rules and information on flying a drone can be found on the CASA website here.
Unless you are licenced or have permission from CASA to do so, the drone safety rules state that you must not fly:
Ensure you understand the rules and where you can fly, before you fly - check the CASA website for further information.
