    Division of Mackellar

    Mackellar was created in 1949, based on the northern beaches suburbs of Sydney, and its boundaries have not changed much since. This is an affluent area and until 2022 the seat was always safe for the Liberal Party. It is among the top 10% of electorates in terms of median family incomes, although its proportion of people in professional occupations is not as high as those in seats closer to the city centre. Between 1949 and 2016 Mackellar had only three members, all ministers in Liberal governments. Bill Wentworth, after a long career as an eccentric backbencher, was a minister in the McMahon government, and Jim Carlton was a minister in the Fraser government, and shadow treasurer during Dr John Hewson's leadership.

    Bronwyn Bishop was elected to the Senate in 1987 (as the first female Senator from NSW), and was on the opposition front bench from 1989. She shifted to the House of Representatives at the 1994 by-election following Carlton's resignation She was a junior minister in the Howard government but was dropped after the 2001 election. She was elected Speaker during the Abbott government. She was highly partisan in this role, and found little sympathy when she was accused of abusing her entitlements. She denied this, but resigned in August 2015.

    Bishop was determined to stand again in 2016, but at 73 she could not rally support and was defeated in a party ballot. She was the longest-serving female member in the history of the Australian Parliament.

    Jason Falinksi, who won Mackellar in 2016, was a Warringah councillor before his election. He seemed secure in a safe Liberal seat, but he became a victim of the Morrison Government's increasing unpopularity with upper-income urban voters. At the 2022 election he was unexpectedly defeated by an an independent.

    Dr Sophie Scamps, independent MP for Mackellar since 2022, was a general practitioner before her election. She has a master's degree in science from Oxford. She practised emergency medicine in Canberra and at Royal North Shore and Mona Vale Hospitals, before becoming a GP.
