The battle for the high-profile Sydney seat of Wentworth, once a Liberal stronghold held by former prime minister Malcolm Turnbull, is going down to the wire with no party yet game to declare victory.
The Liberal's Dave Sharma is leading independent Kerryn Phelps by just 1751 votes on Sunday night, almost 24 hours after Scott Morrison declared victory for the coalition in the 2019 federal election.
Mr Sharma has 51.16 per cent of the vote while Dr Phelps has 48.84 per cent after preferences on Sunday evening.
About 75 per cent of all ballots have been counted and postal votes and prepoll votes will be required to reveal the winner of the knife-edge contest.
The Liberal stronghold swung to Dr Phelps in the October by-election that followed the ousting of Mr Turnbull in 2018.
Mr Sharma, the former ambassador to Israel, went into the federal election confident voter anger over the ousting had subsided in the months since.
Both candidates remained tight-lipped on Sunday evening, with sources telling AAP they would wait for a winner to emerge before fronting media.
