Bill Shorten has vowed to take steps to make Australia a republic in his first term as prime minister, saying the country's current head of state "is a foreign power".
At the Australian Republic Movement's gala dinner in Melbourne, he pointed to the words "carpe diem" on the ceiling of Melbourne's Royal Exhibition Building.
"We must seize the day and become a republic," he told the cheering crowd.
He promised a Shorten Labor government will take "the first real steps to make Australia a republic in the first term of government".
That would include putting a "straightforward" 'yes or no' question to the Australian people. It had been a quarter century since the Queen told former Prime Minister Paul Keating that she would respect the decision of the Australian people to become a republic.
