Abbott and Gillard commenced a 17-day period of negotiation with crossbenchers over who would form government. On the crossbench, four independent members, one member of the National Party of Western Australia and one member of the Australian Greens held the balance of power. Following the negotiations, Gillard formed a minority government with the support of an Australian Greens MP and three independent MPs on the basis of confidence and supply. Another independent and the WA National gave their confidence and supply support to the Coalition, resulting in Labor holding a 76–74 tally of votes on the floor of the Parliament. The Coalition finished with 49.88 percent of the two party preferred vote, obtaining a national swing of around 2.6%.
