The Australian Electoral Commission hopes to be in a position to announce the first official results of the federal election this week, with vote counting continuing over the weekend.
One week on from the national poll, the commission said a number of the 151 House of Representative seats will require a full distribution of preferences before a result can be declared.
The complex Senate vote count also remains in full swing.
"The mammoth task of capturing, confirming, manually entering and then validating the 100 million plus preferences marked on Senate ballot papers has been progressing smoothly," the AEC said in a statement on Saturday.
"More than 1.4 million Senate ballot papers have been scanned since central Senate scrutiny processes began on Wednesday."
On a two-party preferred basis, Labor's Chris Hates has secured 49,072 votes in Fowler compared to Liberal candidate Waye Blewitt's 27,132. That is a three per cent swing to Liberal with 82 per cent of the votes counted.
In McMahon, the Liberals had a five per cent swing with 81 per cent of the vote count. Chris Bowen (Labor) retained his seat with 43,067 votes with Vivek Singha (Liberal) getting 33,103 of the two-candidate preferred vote.
As of Saturday night, two lower house seats were deemed too close to call.
The Liberals' Sarah Richards is just ahead of another Labor incumbent Susan Templeman in the NSW seat of Macquarie, with the AEC website showing a slim 46 vote gap after 88 per cent of votes were counted.
The AEC now has the Liberal-National coalition with a two-seat majority of 77 seats, and the potential of 78 in total. Labor has 66 seats, with the possibility of 67, and there are six crossbenchers.
