Independent Kerryn Phelps is still expected to win the Wentworth by-election, despite postal votes giving the Coalition a hope it can hang on to the electorate.
Dr Phelps claimed victory on Saturday night when she achieved an unprecedented swing of more than 20 per cent against the Liberal Party in the eastern Sydney seat.
But the margin between her and Liberal candidate Dave Sharma has narrowed to just under 1,200 votes with postal ballots still being counted.
Mr Sharma has told Sky News he is hopeful of a win.
If Dr Phelps is confirmed the winner, there will be a crossbench of six members in the House of Representatives, with Labor holding 69 seats and the Coalition one short of a majority with 75.
