{{main|Chapter VIII of the Constitution of Australia}}
The procedure for amending the [[Constitution of Australia]] is detailed in [[Section 128 of the Australian Constitution|section 128 of the Constitution]]. Firstly, a bill amending the Constitution must be passed by both houses of the [[Parliament of Australia]] by an [[Majority#Related terms|absolute majority]] (at least 76 of the 151 members of the [[House of Representatives (Australia)|House of Representatives]] and at least 39 of the 76 members of the [[Senate (Australia)|Senate]]). If one house passes the bill while the other refuses, it may attempt to pass the bill again. If the second house again refuses to pass it, the [[Governor-General of Australia|Governor-General]] (presumably on the [[Advice (constitutional)|advice]] of the [[Prime Minister of Australia|Prime Minister]]) may still submit the proposed change for referendum.<ref name="blackshield & williams">{{cite book|last1=Blackshield|first1=Tony|title=Australian Constitutional Law and Theory: Commentary and Materials|last2=Williams|first2=George|publisher=Federation Press|year=2010|isbn=978-1-86287-773-3|edition=5|location=Leichhardt (Sydney)|pages=1340–1369}}</ref><ref>[[Constitution of Australia]], section 128.</ref>

Following this, Australians then vote on the proposal. For a referendum to succeed both of the following must be achieved

# A majority of states (New South Wales, Victoria, Queensland, Western Australia, South Australia and Tasmania) must agree to the proposal.
# A majority of the combined votes of all of Australia must agree to the proposal.

The double majority is a major factor in why since 1906 out of 44 referendums only 8 have been successful.{{citation needed|date=November 2020}}
