Prime Minister Scott Morrison is set to secure majority government with the Liberals expected to win several tight races, including Malcolm Turnbull's old seat of Wentworth.
Labor is expected to end up with 68 seats, and six MPs will sit on the crossbench, including three independents.
The independent incumbent in Wentworth Kerryn Phelps conceded defeat on Monday to the Liberal candidate Dave Sharma on Monday.
The AEC's projection is in line with ABC's election guru Antony Green, who believes the Coalition will also pick up Chisholm and Bass, while the Labor candidate in Boothby has conceded defeat to incumbent Nicolle Flint.
There's been a swing towards Labor in Chisholm in Melbourne's east, with only a small number of votes separating the Liberal Party's Gladys Liu and Labor's Jennifer Yang.
The Liberals are ahead in Bass in Tasmania, while the ALP leads in Wayne Swan's former seat of Lilley in Queensland and Macquarie in New South Wales.
In Cowan in Western Australia, Labor's Anne Aly is expected to win.
Labor candidate for Cowan Anne Aly is ahead, but there is still a quarter of votes to be counted.
