UPDATE: Maddern cleans her office as Labor holds lead

UPDATE: Anne Maddern has begun cleaning her office as the anxious wait for a decision on who will represent Maryborough continues.

With about 400 postal votes expected to be counted on Monday afternoon, Ms Maddern said the tidy-up would prepare her for either situation.

Labor's Bruce Saunders holds his lead in the notional result- clearing Ms Maddern by 7%.

Independent Chris Foley will rely on strong postal vote support if he is any chance of challenging for the seat.

More in tomorrow's Chronicle.

EARLIER: All eyes will be on the Maryborough electorate, with LNP incumbent Anne Maddern, ALP's Bruce Saunders and independent Chris Foley still in the race.

The notional result, after the distribution of early preferences, shows Mr Saunders with 53% of the vote and Ms Maddern with 47%.

The primary result so far with more than 75% of the roll counted, shows Ms Maddern with almost 30% of votes, Mr Saunders with nearly 26% and independent Chris Foley holding close to 22%.

Analysts predict Mr Foley still has a slim prospect of winning on preferences if he can gain a further 1000 votes.

A third of Maryborough's roll has yet to be counted and full preferences haven't been distributed.

An Electoral Commission of Queensland spokesman said a seat wouldn't be declared while there was a mathematical possibility of another candidate winning.

"Results in some of the tight seats may not be known for a few days until absentee votes are transferred, or even later if we have to wait for all postal votes to come in," he said.

"The deadline for the return of postal votes to returning officers is 10 days after polling day."

After early preferences, Mr Saunders is leading the LNP member by about 6% in two-party preferred.

But even if he doesn't fall over the line, he praised his team for bring Labor back from oblivion in 2012 when the party attracted just 11% of the vote.

On Saturday night, Mr Saunders gathered with more than 100 of his loyal supporters, dubbed the 'Saunders' soldiers.'

Their party at Mr Saunders' home on the outskirts of Maryborough was upbeat, a stark contrast to Ms Maddern's gathering.

Her entourage were notably quiet as the votes came in, and with the LNP losing government almost a certainty, Ms Maddern said she was "gobsmacked" and anxious about her own result.

"It's not a good night for Queensland - they will regret their decision," she said.

When asked about a TV station predicting she would get the boot, Ms Maddern replied; "that would probably be a reasonable assumption".

But sitting in the second most marginal seat, Ms Maddern hasn't fallen just yet in the swing against the LNP.

"I've gone against a trend because I'm hanging on," she said.

Mr Foley sat among friends at the Powerhouse on Kent St on Saturday night, still confident it would be him and Mr Saunders duelling for the win.

But he acknowledged it would be a long-shot, and said he'd retire if he wasn't elected.

"This is the last hurrah," he said.

"If I don't win I'll write my memoirs."
