Victorian parliament will adjourn for one week out of respect for Queen Elizabeth II, after MPs swear their allegiance to King Charles III, the state government has confirmed.
Premier Daniel Andrews on Friday flagged it was likely the state legislature would push back its final three sitting days before the November state election in the wake of the monarch's death.
However, it cannot resume until MPs swear allegiance to King Charles III.
The government on Saturday confirmed that, following the King's proclamation as the Queen's successor, both houses would sit on Tuesday so members could be sworn in by oath or affirmation.
Following the re-swearing, the Legislative Assembly and Legislative Council would adjourn for one week as a mark of respect, and return to sit on September 20 in line with NSW parliament.
"That day of sitting will be used for a motion of condolence for Her Majesty Queen Elizabeth II, with both Houses adjourning for the day at the motion's conclusion," Victoria's Department of Premier and Cabinet said in a statement on Saturday.
"The Parliament of South Australia is also delivering messages of condolence on (September 20)."
September 21 and 22 would be normal sitting days, with valedictory speeches to be given by retiring members.
Victoria is the only jurisdiction where MPs are required to swear allegiance to the new monarch following the predecessor's death.
There will not be a state memorial service for the Queen but sites are expected to be set up for Victorians to watch her funeral from Westminster Abbey.
