seats, the Greens on 10 seats and a crossbench of eight—Palmer United on three seats, with other minor parties and independents on five seats (the LDP's David Leyonhjelm, Family First's Bob Day, Motoring's Ricky Muir and incumbents Nick Xenophon and the DLP's John Madigan). Muir announced he would vote in line with Palmer United. The initial election saw Wayne Dropulich of the Australian Sports Party win a seat in Western Australia, but the subsequent voiding of the result and ensuing special election saw the Palmer United Party gain a third seat. The Coalition government required the support of at least six non-coalition Senators to pass legislation. A record number of candidates stood at the election. Group voting tickets came under scrutiny because multiple candidates were provisionally elected with the vast majority of their 14.3 per cent quotas coming from the preferences of other parties across the political spectrum.
