, the division's namesake The Division was proclaimed at the redistribution of 14 September 1984, and was first contested at the
1984 election. The division was named after
Sir Robert Menzies, the longest serving
Prime Minister of Australia, who represented the neighbouring division of
Kooyong during his time in office. The Division had always been a fairly safe to safe
Liberal seat since creation. It was first held by
Neil Brown, a former minister who served in the
Fraser government and who also served as deputy Liberal leader under
John Howard from 1985 to 1987. Brown retired in 1991 and was replaced by
Kevin Andrews, who held the seat for 31 years, from 1991 to 2022. Andrews was the
Father of the House, with the longest continuous tenure of any then current MHR—although
Warren Snowdon and
Russell Broadbent were first elected earlier. Andrews lost party pre-selection to
Keith Wolahan prior to the
2022 Australian federal election. In the election, the Liberal Party nearly lost the seat for the first time in its history, with Wolahan winning the seat with a 0.7% two-party preferred margin. The swing against the party was attributed to backlash against the
Morrison Government by
Chinese Australians. The 2024 redistribution and accompanying boundary changes erased the Liberal majority and made Menzies a notional
Labor seat with a 0.4% margin. Wolahan needed a swing in his favour in order to be re-elected in the subsequent
2025 federal election. At the election, Wolahan was defeated by Labor candidate
Gabriel Ng, who picked up a small swing in his favour amid the Liberals' collapse in urban seats. Ng is the first Labor member ever to win the seat. ==Boundaries==
