Victoria's governor has proclaimed Charles III as Australia's King and re-sworn officials in a ceremony witnessed by state leaders and luminaries.
Governor Linda Dessau re-swore Victoria's Lieutenant-Governor James Angus and acting Supreme Court chief justice Karin Emerton after an official proclamation ceremony at Government House on Monday.
The re-swearing of senior public office holders and members of parliament following the death of the reigning monarch is unique to Victoria's constitution.
It is not required in other Australian states and territories, which hosted their proclamation ceremonies on Sunday.
Premier Daniel Andrews and Opposition Leader Matthew Guy attended, along with former state leaders Steve Bracks, Ted Ballieu and Denis Napthine.
Ms Dessau paid tribute to Queen Elizabeth II and recalled the fanfare she elicited during her first of 11 visits to Victoria in February 1954, when an estimated million people lined the streets of Melbourne to greet her and Prince Phillip.
The governor offered her condolences to King Charles III and reflected on his "special connection" with Victoria, having spent two terms at Geelong Grammar School in 1966.
Victorian MPs will be re-sworn and a condolence motion held on Tuesday before state parliament adjourns to next week as a mark of respect.
