"Has Australia ever had a referendum at the same time as a federal election?"

Glad you asked – yes!

Since 1901 there have been 19 referendums, proposing forty-four changes to the Australian Constitution; only eight changes have been agreed to. Of these nineteen referendums, eight occurred at the same time as a federal election – these dates are:

12 December 1906

13 April 1910

31 May 1913

13 December 1919

17 November 1928

28 September 1946

18 May 1974

1 December 1984.

It is up to the Australian Government to choose the topic and timing of a referendum, although they will need to follow the requirements of Section 128 of the Constitution.
