The result leaves the Turnbull government with 76 of the 150 seats in the House of Representatives. Labor and the crossbenchers will hold 74 seats together.

Once the Coalition provides a Speaker, it will have 75 votes. The Coalition will therefore still be able to govern in its own right but with the barest possible majority of one.
