Dr Kerryn Phelps, the Independent who won a by-election in the inner-Sydney seat of Wentworth after Malcolm Turnbull was ousted as Prime Minister, has conceded defeat.
Dr Phelps thanked her staff and volunteers during a media conference in Steyne Park, Double Bay.
Saturday's Federal Election saw the seat return to the Liberals, with Dave Sharma to be the electorate's new MP.
Congratulations @DaveSharma on winning Wentworth - the best part of the best country in the world! Good luck in the years ahead. And thank you @drkerrynphelps for the great courage and character you showed as our MP.
Dr Phelps urged the now majority Morrison Government, to address the issues of climate change, plastics pollution and ABC funding - and to establish a federal anti-corruption commission. - Video by Pnina Hagege
