the CP on election to parliament. Independent: Michael Townley (Liberal Party from Feb 1975) Seats changing hands Aftermath Election result The Whitlam government had been re-elected with their majority in the House of Representatives reduced from 9 to 5 seats, while they gained 5 seats in the Senate. The ALP and the coalition each won 29 seats in the 60 member Senate, with the balance of power held by Steele Hall of the Liberal Movement, and Michael Townley, a conservative independent. The Democratic Labor Party, which had been rendered obsolete by the election of the Whitlam government in 1972, lost all five of its Senate seats. Al Grassby, who was Minister for Immigration in the Labor Whitlam government, lost his seat.

The Health Insurance bills were both passed on party lines, 95–92, the Petroleum and Minerals Authority legislation also passed on party lines, though with one Liberal Party member absent. Liberal Movement Senator Steele Hall supported the three Electoral bills, citing his experience as Liberal Premier of South Australia, where he had fought his own party in an effort to improve unequal electoral arrangements dubbed the Playmander. Northern Territory Country Party MP Sam Calder supported the Territory Senators legislation, though he opposed the ACT being given added representation. Subsequent changes In February 1975, the independent senator Michael Townley joined the Liberal party. This gave the Coalition 30 out of 60 Senators, with 29 Labor and 1 Liberal Movement (Steele Hall). Later in 1975, two Coalition premiers would break longstanding convention in the replacement of two
