a majority of the primary vote and had to rely on preferences. Zimmerman faced a double-digit primary vote swing − more than triple that of the 2015 Canning by-election − even though Labor did not even contest the seat. The Liberal two-candidate-preferred vote of 60.2 percent against independent Stephen Ruff compares to the previous election vote of 65.9 percent against Labor. The reduction of 5.7 percent could not be considered a "two-party/candidate preferred swing" − when a major party is absent, preference flows to both major parties does not take place, resulting in asymmetric preference flows. Zimmerman became the first openly LGBTI member of the House of Representatives. He won the seat in his own right in 2016 and 2019. However, in 2022, he lost over 13 percent of his primary vote and was defeated by teal independent Kylea Tink, the second non-Liberal ever to win it. The most notable member for the seat was Billy Hughes, Prime Minister of Australia from 1915 to 1923, and later a minister in the Lyons, Page, Menzies and Fadden governments. Hughes is the longest-serving parliamentarian in Australian history. He transferred to Bradfield after it was carved out of North Sydney's northern portion in 1949, and died as that seat's member in 1952. Other notable members include Mack, Hockey, and Dugald Thomson, a minister in the Reid Government. Boundaries Since 1984, federal electoral division boundaries in Australia have been determined at redistributions by a redistribution committee appointed by the Australian Electoral Commission. Redistributions occur for the boundaries of divisions in a particular state, and they occur every seven years, or sooner if a state's representation entitlement changes or when divisions of a state are malapportioned. Located along Sydney's Lower North Shore, the division is named after the suburb of North Sydney. It also includes the suburbs of Artarmon, Cammeray, Castlecrag, Crows Nest, Greenwich, Henley, Hunters Hill, Huntleys Cove, Huntleys Point, Kirribilli, Lane Cove, Lane Cove North, Lane Cove West, Lavender Bay, Linley Point, Longueville, McMahons Point, Middle Cove, Milsons Point, Naremburn, North Willoughby, Northbridge, Northwood, Riverview, St Leonards, Waverton, Willoughby, Willoughby East, Wollstonecraft, and Woolwich; as well as parts of Chatswood, Chatswood West, Cremorne, Gladesville, Gore Hill, and Neutral Bay.
