Liberal candidate Sarah Richards has widened her lead over Macquarie's incumbent Labor Member Susan Templeman in the fourth day of counting for the 2019 federal election.
Latest figures from the Australian Electoral Commission (AEC) published before 9pm yesterday (Tuesday) showed Ms Richards ahead by 151 votes on a two party preferred basis, with 87.09 per cent of votes counted.
The figures gave Ms Richards a total of 50.08 per cent of the vote, and Ms Templeman 49.92 per cent.
Ms Richards had started the day with just a 50-vote lead, and the AEC started counting around 3,800 absentee votes yesterday afternoon.
Both candidates maintain the seat is still too close to call, and counting is due to resume today (Wednesday).
