1906 Australian federal election

The Protectionist minority government fell in November 1908 to Labour, and a few days later Reid resigned as Anti-Socialist leader, being replaced by Joseph Cook.

The Labour minority government fell in June 1909 to the newly formed Commonwealth Liberal Party led by Deakin; this Party was formed on a shared anti-Labour platform as a merger organised between Deakin, the leader of the Protectionists, and Cook, the leader of the Anti-Socialists, to counter Labour's growing popularity.

Reid envisaged a spectrum running from socialist to anti-socialist, with the Protectionist Party in the middle.

This attempt struck a chord with politicians who were steeped in the Westminster tradition and regarded a two-party system as very much the norm.

The proposed alteration to the Constitution, to change the start date of Senators' terms from 1 January to 1 July, passed in all states and was carried.

Labour: 26 seats
Protectionist: 16 seats
Anti-Socialist: 26 seats
Independent: 6 seats
Western Australian: 1 seat
