8.00 pm, the first personality to call the election was former Labor Prime Minister Bob Hawke on Sky News. At 10.29 pm AEST, approximately two hours after the last polls in Western Australia closed, Liberal deputy leader Peter Costello conceded that the Coalition had lost government. At 10.36 pm, John Howard delivered a speech at the Sofitel Wentworth Hotel in Sydney to concede defeat. At 11.05 pm, Kevin Rudd delivered his victory speech. Labor won 83 of the 150 seats in the incoming House of Representatives. This represented a 23-seat swing to Labor. The Liberals won 55 while the Nationals won 10, with two seats retained by Independents. Labor finished with a 52.70 per cent two-party-preferred vote, a 5.44-point swing from 2004. On preferences, 79.7 per cent of Green votes flowed to Labor, 60.3 per cent of Family First votes flowed to the Coalition, with 62.5 per cent of Democrat votes flowing to Labor. Considering two-party estimates going back to the 1949 election, the swing to Labor in 2007 was the fourth-largest two-party-preferred swing, behind John Curtin and Labor in 1943 on 7.9 per cent, Malcolm Fraser and the Coalition in 1975 on 7.4 per cent, and Gough Whitlam and Labor in 1969 on 7.1 per cent. The swing was the largest since 1983, when full preference counting was introduced to create an exact two-party figure, and the largest swing to occur in the absence of a recession, political or military crisis. Western Australia went against the national trend, with the Liberals suffering only a 2.14-point swing against them – lower than all except Tasmania and the ACT – but yet gaining one net seat. The weaker Labor performance was attributed to the strong economy and voters' unwillingness to do anything which might risk their present prosperity – a sentiment played to by Liberal campaigning strategies – and also the behaviour of union officials Kevin Reynolds and Joe McDonald who had made headlines during the campaign. Senate Labor and the Coalition won 18 seats each in the half-Senate election. The Greens won three seats, with Independent Nick Xenophon being elected on primary votes alone. This took the 76-member Senate total to 37 Coalition, 32 Labor, 5 Green, 1 Family First, and 1 Independent. With a majority being 39 senators, when the new Senate met after 1 July 2008, the balance of power was shared between Xenophon, Family First's Steve Fielding
