It was Robert Menzies, father of the modern Liberal Party, who famously remarked: “to get an affirmative vote from the Australian people on a referendum proposal is the labour of Hercules”.
Menzies knew this from bitter experience. The politician with the electoral Midas touch was the sponsor of three unsuccessful referendums. Most notable was Menzies’ (thankfully) failed 1951 attempt to win public support for amending the Constitution to grant his government the power to outlaw the Communist Party of Australia.
On the Labor side of politics, the feat of constitutional change has been an even more unfulfilling exercise. The party has been responsible for 25 amendment proposals and only one has been successful. It has been a truly Sisyphean quest.
