Tony Abbott's sister Christine Forster believes she would make a good Liberal candidate for Malcolm Turnbull's soon-to-be-vacated Sydney seat as several big names jostle for the position.
Ms Forster said she was being encouraged by several people within the party to run for Liberal pre-selection in Wentworth to replace the ousted prime minister.
Mr Turnbull is yet to announce his resignation from the harbourside seat but told reporters last week it would be "not before too long".
"If and when the seat becomes available I'm considering nominating," Ms Forster told AAP on Monday.
The City of Sydney councillor said she had a strong record of championing Liberal Party values at a local government level.
"I think as someone with local credentials and a strong track record of strong liberalism, I feel they are the types of candidates we want in any seat," Ms Forster said.
"I've been strong in espousing and representing Liberal values in the city of Sydney."
Businessman and former Australian ambassador to Israel Dave Sharma is said to be the frontrunner to replace Mr Turnbull as the Liberal candidate. NSW MP Alex Greenwich and health advocate Dr Kerryn Phelps are also both considering running as independents.
Waverley Deputy Mayor Dominic Wy Kanak has been announced as the Greens candidate for the seat.
Tamarama Surf Lifesaving Club president and local businessman Tim Murray will run as Labor's candidate.
