Labor is now one seat away from forming a majority government.
ABC chief election analyst Antony Green called the Tasmanian seat of Lyons for the Labor Party on Thursday afternoon, taking the ALP to 75 seats.
This means four seats still remain in doubt.
This is how things are looking on a national level at the moment.
These are the seats still in doubt
Brisbane, Queensland
With 69.1 per cent of the votes counted, the Greens candidate Stephen Bates is in the lead by 6,433 votes.
Mr Bates has said he was "cautiously optimistic" that he will win the seat, describing the city as always being a "microcosm of progressivism".
Liberal National Party's Trevor Evans is the current member for Brisbane.
Deakin, Victoria
The seat of outgoing Liberal assistant treasurer Michael Sukkar is still a close call.
Mr Sukkar is ahead of the Labor Party's Matt Gregg by 890 votes.
Gilmore, New South Wales
It's a narrow margin in the federal seat of Gilmore on the NSW South Coast, with only 114 votes separating Labor incumbent Fiona Phillips and Liberal challenger, former NSW transport minister Andrew Constance.
More postal votes are also expected and anticipated until June 3.
Macnamara, Victoria
Labor's Josh Burns leads by 17,885 votes.
The ABC is projecting a Green versus Labor final preference count but, at this stage, it is unclear what order the three leading first-preference candidates will finish, says ABC’s chief election analyst Anthony Green.
"Estimates provided to me are that the exclusion of the five lowest-polling candidates produces preference flows of 18 per cent to Labor, 34 per cent to the Greens and 48 per cent to Liberal," Green said.
"Applying those puts the final three candidates within 1,000 votes of each other."
This seat was called on Thursday:
Lyons, Tasmania
Labor's Brian Mitchel has retained the Tasmanian seat of Lyons, defeating the LNP's Susie Bower, ABC chief election analyst Anthony Green says.
Lyons is Tasmania's largest electorate and takes in just less than half of the state.
When will vote-counting finish?
Australian Electoral Commission staff have been sorting and counting votes since polls closed on May 21.
Alongside the votes made in person, there has also been a mountain of postal votes to sort through, with many of these taking up to two weeks to arrive before being counted.
This is why these postal votes could be vital in determining the outcome in some extremely close but narrow seats.
