Neither the Coalition nor Labor would command a majority in the House of Representatives if the 2016 election results were replicated under a proportional voting system.

The two major parties would have needed to reach out to 24 crossbenchers, including independents and representatives from five minor parties, to guarantee confidence and supply.

If the July 2 poll's results were replicated under the "D'Hondt method" of proportional representation, the combined coalition of the Liberal, LNP, Liberal Country and National parties would pick up 68 seats, eight short of a majority.

Labor would take 58 seats, but would need to enter into a coalition with the 14 Greens MPs and at least four other crossbenchers to secure the confidence of a majority of the house.
