Some Facts

The IVAO Oceanic Region is responsible for Australian, New Zealand, New Calidonia and Papua New Guinea's airspace.
Operating under the IATA code (XO) the division manages the airspace from Mauritius airspace to Chilean airspace including Antarctica.

The Oceanic Division is responsible for the airspace stretching in latitude from 2 degrees to 90 degrees south; and in longitude from 75 degrees to 150 degrees east. This is an area of approximately 121,398,884 sq nautical miles (416,386,449 sq kms) - or some 26 percent of the world’s total airspace.

Our region holds a huge amount of airspace a lot of which is oceanic, this airspace is unique and differs from every other oceanic airspace with the structure and routing through these airspaces.
However with in the oceanic airspace there is a large amount of domestic airspace.
Our domestic airspace hides numerous unique challenges from mountainous approaches in New Zealand to the dry red outback and beach side airfields in Australia.
Being so vast the division has countless airports all of which have different challenges many of which you won’t find elsewhere.

The country has a bit of everything, from scorching hot deserts out the west, to beautiful snowy mountain peaks to the east. Tropical Rain Forests, Beautiful Sandy Beaches.

General guidelines

When operating in the Australia, please observe the following general IVAO XO rules:


Whenever practicable, 122.800 and 121.500 should be continuously monitored unless another frequency (ATC station for example) is more appropriate.


All altitudes are above mean sea level (AMSL) in feet.
Transition altitude: 10000ft .
Transition level: FL110.

Squawk codes

The following codes are allocated for use by pilots, without direction from ATC for the purposes specified.
Use these codes unless ATC instruct otherwise:
Code 7700 - Aircraft Emergency
Code 7600 - Radio Failure Note, the code 7500 (hi jack) is NOT to be used on the IVAO Network
Code 2000 - When entering Australia airspace from an adjacent region when no SSR code has been assigned
Code 7000 - When not receiving a service from an ATS unit in class F/G airspace

Speed restrictions

Do not exceed the 250kts IAS below FL100, unless you have permission from ATC, or the classification of airspace you are flying in means you are exempt from the rule. Military aircraft may also exceed the restriction.


Altimeter settings are in millibars and the standard setting is 1013mb.

No available ATC

Intentions must be broadcast on the Unicom frequency of 122.800
