Anthony Albanese wasn't the only Labor member to be sworn into office on Monday — four of his colleagues and cabinet members were as well.
Just after he was officially made Australia's 31st Prime Minister, some of the party's most senior members were also sworn into their roles, ahead of a full ministerial swearing-in in the coming weeks.
The group was sworn in early because of the Quad leaders' meeting between Australia, Japan, India and the United States in Tokyo on Tuesday.
While the full line-up of Labor's frontbench will likely be decided next week, here's who was also sworn into the "interim ministry", and what roles they've been given.
Richard Marles
Deputy Labor leader Richard Marles has, at least for the time being, been given the Employment portfolio.
He will also be Acting Prime Minister while Mr Albanese is out of the country.
The appointment is in line with his role in opposition as Shadow Minister for Employment, Skills and Small Business.
But there are questions around his future in that role, with many believing he will instead choose to become Defence Minister.
As deputy leader, he gets to choose what portfolio he takes on.
In either role he faces some pretty tough issues — as Employment Minister he'll be responsible for maintaining low unemployment while also ensuring there are enough staff to fulfil some of Labor's key policies like more nurses in aged care.
In Defence, he'd be overseeing a portfolio with one of the biggest budgets, submarine capability gaps and also have to tackle how to negotiate the threat of China to Australia and the region.
Mr Marles was first elected to the seat of Corio in Victoria in 2007 and was briefly the Trade Minister for two months in 2013.
Penny Wong
Penny Wong has been sworn in as the Foreign Affairs Minister; she held the shadow portfolio in opposition for six years, since July 2016.
Senator Wong is joining Mr Albanese on the trip to Tokyo in part to discuss Labor's major new package for the Pacific and South-East Asia, including major aid for the region.
She and the Prime Minister have also flagged they want to discuss the threat climate change poses to Pacific nations.
Senator Wong was first elected as a South Australian senator in 2001 and held the climate change and finance ministerial positions when Labor was last in government between 2007 and 2010.
Jim Chalmers
Jim Chalmers has been sworn in as Treasurer, another unsurprising choice given he has held the shadow treasurer role since the 2019 election and shadow finance portfolio before that.
He will be responsible for delivering the first Labor budget in almost a decade once the government is officially formed, which could still be a little while away yet.
According to Labor's costings, its budget bottom line will be $7.4 billion greater than the Coalition's, so the Treasurer will have to grapple with the already historic debt and deficit.
Dr Chalmers was first elected to the Queensland seat of Rankin in 2013.
Katy Gallagher
Katy Gallagher was sworn in as Finance Minister, after holding the shadow finance minister position since 2019.
She was also sworn in as Health Minister, Attorney-General and Minister for Women, but says these are just temporary as part of the interim portfolio.
Along with Dr Chalmers, her role will be focused on how the government manages the economic situation left by the last government.
Senator Gallagher was previously the ACT Chief Minister and made the jump to federal politics in 2016 to fill a senate vacancy.
She was forced to resign from the position in 2018 for being a dual citizen but was re-elected as an ACT senator in 2019.
