The Australian Electoral Commission has listed the WA seat of Hasluck as the only seat still too close to call following Saturday's election.
In the seat of Denison in Tasmania, Independent Andrew Wilkie has grabbed the lead from Labor's Jonathan Jackson.
With more than 80 per cent of the vote counted in that seat the AEC has listed Mr Wilkie as having won the seat from Labor on its website.
However the final result might not be known until near the end of next week as the AEC waits for a deadline to expire on postal votes.
Hasluck remains the tightest contest of the four seats still in doubt.
Labor continues to make inroads into the significant lead Ken Wyatt held on Saturday night.
Only 317 votes separate the pair, and the Liberal advantage might not be big enough to withstand a likely postal vote surge to Labor.
Labor believes about 3,000 postal votes, yet to be counted, will push Sharryn Jackson over the line, dashing hopes the new parliament will include the first-ever indigenous lower house MP.
The other seats which are very close are Boothby in South Australia and Dunkley in Victoria.
Labor frontbencher Craig Emerson said it will be "a job" for Labor to run down Andrew Southcott in Boothby where the sitting Liberal MP is leading by 813 votes.
In Dunkely, sitting Liberal MP Bruce Billson is holding off a Labor challenge. He leads by a few hundred votes with 82 per cent of the count completed.
