Labor incumbent Warren Snowdon is now predicted to retain the Northern Territory seat of Lingiari.
The former Indigenous health minister is locked in a close battle with Country Liberals candidate and Top End pastoralist Tina MacFarlane.
With 68 per cent of the votes for Lingiari counted so far, Mr Snowdon is leading Mrs MacFarlane by 51.4 per cent to 48.6 per cent on a two party preferred basis.
When counting resumed this morning, results from 61 of 74 booths were in for the vast electorate, which covers more than 99 per cent of the Territory.
But Mr Snowdon says a final result may not be known for several days.
He says votes from many of the mobile polling booths in remote parts of Lingiari have not been counted yet and he hopes to hold on.
Mr Snowdon says he suffered from the national swing against Labor, and history could repeat itself if he loses his seat.
"I was the last seat to fall when [Paul] Keating lost in 1996, so I know how this feels," he said.
"I wouldn't mind betting that if I don't get over the line, I'll be the last one.
"I haven't given up.
"I think there are still quite a few thousand votes to count ... mostly come from the bush.
"We expect we'll do reasonably well in some of those booths and, if we do as well as we should do, we are a very good chance of retaining the seat.
"But it will be difficult."
Lingiari has been held by Mr Snowdon since it was created in 2001, but the seat shifted from safe to marginal in 2010 after many remote Indigenous voters abandoned the ALP.
