Anthony Albanese will attend the funeral of Queen Elizabeth with his partner Jodie Haydon.
The palace has yet to confirm a date for the funeral, but Australian officials have said a six-person delegation will attend the funeral.
They include Prime Minister Ms Haydon, Governor General David Hurley and his wife Linda.
Acting United Kingdom High Commissioner Lynette Wood, former ambassador to Germany, will also attend with her partner.
A national day of mourning will be held after the prime minister returns from a funeral in London, but it is not yet clear when that will be or if it will be a public holiday.
Today at 17:00, 96 shots will be fired in front of the Parliament building, symbolizing each year of the life of the monarch, and at 10:00 a wreath-laying ceremony will take place on the Queen’s terrace.

On Sunday, the prime minister will recommend to the governor general that King Charles II be proclaimed king. There will also be a salute of 21 guns.
Government sources have confirmed that Mr Albanese will write to the Secretary of Defense asking for the help of the Defense Forces in arranging transport to the United Kingdom.
Defense forces personnel will also be invited to the states and territories to participate in their own events commemorating the death of Queen Elizabeth.
While some shops in London will close on Friday as a show of respect, in Australia everything will be open as usual without the need to reduce opening hours for pubs and shops.
Earlier today, the Prime Minister said he and Governor General David Hurley would travel to London as a sign of respect.
“Queen Elizabeth II was a wise and inspiring mentor. Always wishing the best for our nation and welcoming every change with understanding, goodwill and unwavering faith in the voice of the Australian people,” he said.
“It was clear from her first trip here that Her Majesty holds a special place in our hearts. And we are in it.
Liberal leader Peter Dutton said Australians “admired her relentless service”.
“Our queen not only earned our trust, she also won our admiration,” he told ABC News Breakfast.
“Her Majesty Queen Elizabeth II lived through the key events of the 20th and 21st centuries. Wars, conflicts, depressions and recessions. The end of the empire and decolonization, the flight to the moon and the acquisition of civil rights.
“One of the fires of humanity has gone out. May our memories of our dear Queen inspire us to do our very best.”
Former United Kingdom High Commissioner George Brandis said the Queen was not only a respected world leader, but also a warm and charming woman who “looks like your grandmother”.
“And more than just a favorite figure. She was the only monarch that almost everyone can remember,” he said.
“She was so easy to talk to. She was very friendly. I know it sounds like a cliché, but she was like your grandmother. She spent her life comforting people. And she was the easiest.”
