Ms Gillard has cited Labor's lead in the two-party preferred vote as the key reason why Labor should form government.
With 80 per cent of votes counted, the coalition has taken a narrow lead with 50.1 per cent compared to 49.9 per cent for Labor, according to AEC figures.
But Ms Gillard said what was now on the AEC website was the two-party preferred vote for 142 seats where Labor and the coalition went head to head.
That excludes some seats, for example, where Labor and the Greens were the main contenders.

Ms Gillard said experts like ABC electoral analyst Anthony Green were saying the AEC's currently displayed two-party preferred vote was wrong for that reason.
She said the AEC was following its normal procedures but at the end of the counting process would count the two-party preferred vote for Labor and the coalition for all 150 seats.
"As I am advised even with seats like Grayndler and others excluded from the count, Labor was ahead in the two-party preferred," she said.
