Two proposals to amend the Australian Constitution were submitted to the Australian electorate in November 1999. If approved, the referendum would have established a republican system of government in Australia. The referendum held on 6 November 1999 failed to achieve the support of either a majority of voters or a majority of states. The national vote of the electors in favour of Australia becoming a republic was 45.13%, with 54.87% against. Australia remains a constitutional monarchy.
