 The Legislative Council election held on the same day was the first since significant changes to the Council's structure and manner of voting under the "Constitution Acts Amendment Act (No.2) 1963" (No.72 of 1963).The Act abolished the 10 three-member provinces which had existed almost unaltered since 1900, and created 15 new two-member provinces.Voting became compulsory and the property franchise was abolished, and the practice of having separate Legislative Council elections in May of every even-numbered year was abolished—the Council's members would now go to the voters at the same elections as members of the Legislative Assembly, although the rotational system where one member per province would retire at each election remained in effect, and unlike the Assembly, the Council's term expired on 22 May every three years, rather than at the election itself.
