Final poll counting expected on Monday
Anthony Albanese may be just 24 hours away from finding out whether he has secured a majority government in the lower house, which the prime minister says will send a clear message to his opponents.
There was no fresh counting in the three seats that remain in doubt after the election just over a week ago, according to respected ABC election analyst Anthony Green.
"Staff will be processing declaration envelopes to be ready for a big count on Monday. That should clarify the final result - unless the three seats remain ultra-close," he tweeted on Sunday.
Labor needs 76 seats to gain a majority in the lower house of federal parliament, with the party sitting on 75, according to the Australian Electoral Commission website.
"Having a majority Labor government I think is important in terms of sending a message, but I'm very clear as well that I want to treat the parliament with respect," Mr Albanese told Sky News' Sunday Agenda program.
The AEC considers three seats as tight - Deakin in Victoria, Lyons in Tasmania and Gilmore in NSW.
Liberal MP Michael Sukkar is 655 votes ahead of Labor's candidate Matt Gregg in Victoria's Deakin electorate, which has recorded a swing to Labor of roughly four per cent.
In NSW, sitting Labor MP Fiona Phillips is 214 votes behind Liberal candidate and former state minister Andrew Constance in Gilmore, with postal votes slightly favouring Mr Constance.
Labor incumbent for Lyons, Brian Mitchell, is ahead by 678 votes against Liberal candidate Susie Bower.
A fourth seat is also seen as tight by some pundits - the Victorian seat of Macnamara, where Labor MP Josh Burns has taken a slight lead over his Greens rival Steph Hodgins-May with Liberal candidate Colleen Harkin trailing.
Even with Labor's final count in Parliament House uncertain, the party will hold a caucus meeting on Tuesday where factions can sort out their preferences for the new ministry, which will be sworn in on Wednesday.
Peter Dutton and Sussan Ley are on Monday expected to be endorsed as the new leadership of the Liberal Party.
The Nationals will also meet to vote on a leader with both David Littleproud and Darren Chester set to contest against former deputy prime minister Barnaby Joyce.
