The decision by Turnbull, a former head of the national republican movement, to scrap the honours may be interpreted as a signal of his willingness to revisit the thorny question of Australia’s relationship with the monarchy.
“Knights and dames are titles that are really anachronistic, out of date and not appropriate in 2015,” Turnbull told reporters.
Opposition Greens Party leader Senator Richard Di Natale welcomed the decision, even as he used it to mock the government.
“It says something about the standard of leadership in this country that installing knights and dames was one of the most significant acts of our former prime minister, and undoing that folly is so far one of the most significant acts of our new one,” he said in a statement.
Others who received the honours were governors general Quentin Bryce and Peter Cosgrove, former air chief marshal Angus Houston and New South Wales state governor Marie Bashir, which Turnbull has said they will retain.
Queen Elizabeth is Australia’s largely ceremonial head of state, but has the power to approve the abolition of parliament, which last happened in the controversial 1975 toppling of Gough Whitlam’s government.
Australia’s sometimes strained relationship with the British crown came to a head in a 1999 national referendum, when almost 55 percent of Australians voted against breaking with the monarchy, defeating Turnbull’s republicans.
A poll this year for the Australian National University showed that public support for a republic has fallen further since the referendum, while the royals’ popularity has risen.
But Turnbull’s move into the leadership has buoyed the hopes of republicans eager to revisit the issue in a fresh referendum, despite his ranking of the faltering economy, not the monarchy, as his government’s top priority.
Prince Charles and his wife Camilla are expected to receive a warm welcome when they visit Australia and New Zealand next week.
