The ABC is projecting the Coalition will hold 77 seats in the Lower House, one more than it needs to govern in majority.

The Prime Minister's new-look ministry visited Government House this morning, where the Governor-General swore the frontbench into office.

There was a standing ovation for West Australian MP Ken Wyatt, as he became the first Aboriginal person to sit in Cabinet.

Deputy Nationals Leader Bridget McKenzie became the first woman to serve as Agriculture Minister.

The Prime Minister elevated NSW MP Sussan Ley, West Australian senator Linda Reynolds and South Australian senator Anne Ruston to Cabinet, joining Foreign Affairs Minister Marise Payne and Industry Minister Karen Andrews.

In doing so, he demoted former environment minister Melissa Price from Cabinet.

Labor is considering a legal challenge to a likely Liberal victory in the marginal Melbourne electorate of Chisholm, amid allegations of misleading campaign material and dirty tactics.

There is just one seat that remains in doubt, Macquarie in New South Wales, where Labor incumbent Susan Templeman holds a 67-vote lead with almost 92 per cent of votes counted.

The Opposition will tomorrow select a deputy to serve alongside Anthony Albanese, who assumed the top job uncontested.

There are reports his likely deputy, Victorian Richard Marles, will want the foreign affairs portfolio, which will have implications for Labor's Senate leader Penny Wong, who held that role for the past three years.

Senator Wong is likely to be the only woman in Labor's four leadership roles if her deputy Don Farrell retains his position.

Senator Farrell is facing a likely challenge from former NSW premier Kristina Keneally for his leadership role.

Senator Keneally had been caught in a factional battle to get to Labor's frontbench, but her path was made clear by frontbencher Ed Husic stepping down for her.
