The North Sydney electorate was a federation electorate that was first contested in 1901 and abolished at the 2025 Australian federal election.

It encompassed a thriving urban centre around the northern shore of the Sydney Harbour, extending from Gladesville, Woolwich and Hunters Hill in the west, to Cremorne in the east and Chatswood in the North.

Traditionally under the custodianship of the Cammeraygal and Wallumatta peoples, the former division of North Sydney is home to more than 167,000 people, living in almost 68,000 households across the area. It is a vibrant and diverse community, with almost half of all residents born overseas, and over a third speaking a language other than English at home.

The former electorate was first represented by Dugald Thomson in 1901. It had a total of 11 Federal MPs, including former prime minister Billy Hughes, former treasurer Joe Hockey and “father of the independents” Ted Mack.

It has a high proportion of knowledge workers and is home to many innovative businesses, with a number of software, media, and other high-tech companies based in the North Sydney and St Leonards CBDs.

As a community, North Sydney was known for its passion and compassion. Both the North Sydney and Lane Cove local government areas are active Refugee Welcome Zones, and there is significant support in the community for greater equality: for women, First Nations Australians and asylum seekers.

North Sydney has also long been a centre for environmental advocacy, with local residents demanding greater protections for the many parks and reserves that not only enhance the beauty and livability of our area, but are also crucially important to local wildlife populations and air quality.

Kylea Tink was elected Federal Member of North Sydney in May 2022, becoming the last to serve in this role following the Australian Electoral Commission's decision to abolish the seat in the 2025 Federal Election. Besides Ted Mack, Kylea is the only non-Liberal candidate to have won this seat since Federation and is the first woman to hold the seat.
