Scott Morrison remains on track to win 78 seats in the lower house, with the coalition leading in Tasmania's Bass electorate and Macquarie in NSW.
The Australian Electoral Commission has also added the Queensland seat of Lilley to its list of close seats, bringing the total to three.
Labor leads in Lilley, with AEC figures on Wednesday evening showing candidate Anika Wells leading her Liberal National Party rival Brad Carswell with 50.5 per cent of the two-party preferred vote.
The Liberal candidate for Bass, Bridget Archer, sits on 50.4 per cent of the two-party vote in her electorate - 504 votes ahead of incumbent Labor MP Ross Hart.
In Macquarie the Liberals' Sarah Richards leads Labor MP Susan Templeman, by 196 votes with 88 per cent counted.
In Chisholm, Liberal candidate Gladys Liu holds 50.8 per cent of the two-party preferred vote ahead of Labor's Jennifer Yang.
If the current count trends continue, the Liberal-National coalition will have 78 seats, with Labor on 67 and six crossbenchers.
