in a variety of roles, most prominently as Shadow Attorney-General. When Matt Birney attempted to remove her from the Ministry in March 2006, he lost his own leadership in a party-room ballot to Paul Omodei, who immediately reinstated her. Walker resigned from the Liberal party on 8 February 2008 after Troy Buswell attained the leadership, sitting as an independent thereafter. She contested the 2008 state election, claiming significant local support in doing so. However, at the 2008 Western Australian election, Bill Marmion won the seat for the Liberal Party, defeating Walker by 10,266 to 9,280 on the two-candidate-preferred vote. At the 2017 state election, Marmion suffered a two-party-preferred swing of almost 11 percent, dropping the Liberals' margin over Labor to 8.3 percent, the lowest since 1933. The Labor Party won Nedlands for the first time at the landslide 2021 state election, with Katrina Stratton defeating Marmion on a swing almost as large as the one the Liberals suffered in 2017. Marmion lost over 16 percent of his primary vote from 2017, and Stratton defeated him after Green preferences flowed overwhelmingly to her. Geography Nedlands is bounded by the Swan River to the south and southeast, Thomas Street and Kings Park to the east, Loch Street and Brockway Road to the west, and Cambridge Street to the north. Its boundaries include the suburbs of Crawley, Daglish, Dalkeith, Jolimont, Nedlands, Shenton Park, Subiaco, West Leederville, along with parts of Floreat and Wembley. Major features within the electorate include Subiaco Oval, Karrakatta Cemetery, Sir Charles Gairdner Hospital, University of Western Australia and Parliament House. The 2007 redistribution, which took effect at the 2008 election, resulted in the seat losing most of Wembley and all of West Leederville while gaining part of Floreat and a non-residential section of Shenton Park north of the railway. Demographics Nedlands and the neighbouring electorates of Churchlands to the north and Cottesloe to the west comprise the affluent western suburbs of Perth—the Australian Bureau of Statistics's SEIFA index (2001) ranked them as the highest three electorates by socio-economic status in Western Australia, with high scores on educational and employment opportunity. At the 2006 census, the median individual income in the Nedlands electorate, based on its 2005 boundaries, was $666 per week compared to $513 in the Perth metropolitan area, and the median weekly household income was $1,392 compared to $1,086 across Perth. 58.7% of the population were professionals or
