Following initial reluctance to officially call the outcome (despite confidence of success), McKew declared victory officially on 1 December. At that time, the Australian Electoral Commission showed McKew ahead on a two-candidate-preferred basis, by 43,272 votes to 41,159; however, pre-poll, postal and absent votes were still being counted and could possibly have affected the outcome. Howard formally conceded defeat in Bennelong on 12 December. The Electoral Commission declared the seat, with 44,685 votes for McKew to 42,251 for Howard. McKew led for most of the night, and ultimately won on the 14th count after over three-fourths of Green preferences flowed to her. Voter turnout in Bennelong was 95%. Polls 2010–17 For the 2010 federal election, the Liberal Party pre-selected former tennis professional and tennis commentator John Alexander to contest the marginal seat.

He was reelected in 2016 with a small swing in his favour, even as the Coalition barely won a second term. On 11 November 2017, Alexander resigned his seat over questions of his eligibility to stand under section 44 of the Constitution, necessitating a by-election. 2017 by-election Amid the 2017–18 Australian parliamentary eligibility crisis, the trigger for the by-election was the resignation of Liberal incumbent John Alexander effective 11 November 2017.
