Scott Morrison remains on track to win 78 seats in the lower house, as electoral officials continue to count votes.
Tight counts are underway in three electorates, after the Australian Electoral Commission added Queensland's Lilley to its list of "close" seats late on Wednesday.
Labor leads there, with AEC figures on Thursday evening showing candidate Anika Wells leading her Liberal National Party rival Brad Carswell with 50.5 per cent of the two-party preferred vote.
Ms Wells is trying to replace Labor stalwart Wayne Swan, who has gone on to become the ALP's national president.
The coalition remains in the lead in the other two close counts - Tasmania's Bass and Macquarie in NSW.
Liberal candidate for Bass, Bridget Archer, sits on 50.4 per cent of the two-party vote in her electorate - 561 votes ahead of incumbent Labor MP Ross Hart.
Over 91 per cent of votes for Bass have been counted.
The Liberals' Sarah Richards is ahead of Labor MP Susan Templeman in Macquarie, with the AEC website showing a 131 vote gap in the most recent figures with 88 per cent of the vote counted.
In the previously "close" listed seat of Chisholm, Liberal candidate Gladys Liu holds 50.8 per cent of the two-party preferred vote, ahead of Labor's Jennifer Yang.
More than 60,000 votes cast in 80 countries are now being sorted for distribution to their home seats for inclusion in the election count.
If the current count trends continue, the Liberal-National coalition will have 78 seats, with Labor on 67 and six crossbenchers.
