After the 2022 election, teal independent Monique Ryan became the member for the electorate, unseating former Liberal deputy leader and Treasurer Josh Frydenberg.

The seat's best-known member was Sir Robert Menzies, the longest-serving Prime Minister of Australia.

In 2019, high-profile Greens candidate Julian Burnside received the highest two-party preferred vote against the Liberals or their predecessors in 90 years, at 44.3%.

The Liberals had anticipated a strong contest and doubled their campaign funding to Kooyong earlier in the year, from $500,000 to $1 million.

[8] Frydenberg retained the seat, despite suffering a significant negative swing of 8.81% and the Liberal Party receiving its lowest first preference vote in the electorate in 76 years.

The swing was actually large enough to make the seat marginal in a "traditional" two-party contest with Labor for the first time in decades.
