An identically named Act was passed by the Commonwealth Parliament in Australia, to bring into force the provision of the Paris Convention and the newly created International Commission for Air Navigation (ICAN).

[1] On 25 February 1919, an Australian Air Traffic Committee under the Council of Defence met for the first time.

Major General Legge, chairman of the committee, noted that "there should be only one regulatory air authority for Australia, working under a single legislature."

At an Australian Premiers' Conference in May 1920 the Australian Prime Minister Billy Hughes's recommendation that "each State should refer to the Commonwealth [of Australia] the control of air navigation, but in a way as to reserve to the States the right to own and use aircraft for the purpose of government departments and the police powers of the State" was carried, and the Australian Parliament passed the Air Navigation Act in the widest possible terms.

[1] The Australian Air Navigation Act of 1920 was granted assent on 2 December 1920, gazetted on 11 February 1921, came into force on 28 March 1921 and became law on 28 June 1921.
