Nine seats in the state are on a knife-edge today as the counting of votes from the federal election continues.

Among the political heavyweights at risk of losing their seats are Greens leader Adam Bandt and teal independents Zoe Daniel and Monique Ryan.

Bandt says he is confident of defending his seat of Melbourne, despite Labor candidate Sarah Witty mounting a major challenge.

In what has been a mixed electoral performance, the Greens have conceded defeat in the seats of Brisbane and Griffith.

Meanwhile, Daniel and Ryan remain locked in titanic struggles to retain their Melbourne seats.

Daniel is being challenged in her seat of Goldstein by Liberal candidate Tim Wilson, who was the constituency’s MP from 2016 to 2022.

Daniel will need to pick up large numbers of postal votes to keep her seat, analysts predict.

With 78.4 per cent of the vote counted in the seat of Kooyong, the incumbent Ryan remains marginally in front of Liberal challenger Amelia Hamer.

Ryan said yesterday she expects a final result to take days or even weeks.

The Senate results may also take weeks to be finalised, with Jacqui Lambie is in a tight race to retain her seat.

In the Northern Territory, Labor incumbent Malarndirri McCarthy and Country Liberal counterpart Jacinta Nampijinpa Price will retain their upper house seats. 

The mandatory second count of all votes will be started today by the Australian Electoral Commission.

Officials have counted more than 14 million first preference House of Representative ballot papers since the close of the election last Saturday.
