SITTING member Anne Maddern has conceded the seat of Maryborough, Labor candidate Bruce Saunders says, but the seat has yet to be officially declared by the Electoral Commission of Queensland.
Claiming the seat of Maryborough is vital if the ALP is to be able to form government in Queensland and it is believed a result could be known either on Monday or Tuesday.
One more is seat needed for the party to be able to form a minority government after independent Peter Wellington announced he would "conditionally" support the Labor Party.
Speaking from his gelato business in Bazaar St, Mr Saunders said Mrs Maddern, who held the seat for the LNP, had called him and conceded the seat.
Mr Saunders said he was about 801 votes in front after preferences.
"It's looking positive - we are in front," he said.
The Chronicle phoned Mrs Maddern but was unable to get a response.
However Mr Saunders said he was impressed with the campaign Mrs Maddern had run, calling her a "very formidable opponent".
"She ran a very good, very clean campaign," Mr Saunders said.
"She held herself very well throughout the campaign."
Mr Saunders said it was likely the seat would be declared some time on Monday as there were still votes outstanding.
But about 97% of the vote had been counted, he said.
Labor leader Annastacia Palaszczuk says she is "optimistic" Labor will lead Queensland before long.
"Labor remains hopeful and optimistic that we will be able to form government," Ms Palaszczuk said.
Independent candidate Chris Foley was on his way to the Gold Coast when the Chronicle spoke to him and said he had not been keeping a close watch on developments as the voting continued.
