Since 1918, Labor had called for the abolition of the existing Australian Constitution, and the vesting of all political power in Parliament, a plan which would turn the states into powerless geographic regions. Beginning in 1965, Whitlam sought to change this goal. He finally succeeded at the 1971 ALP Conference in Launceston, Tasmania, which called for Parliament to receive "such plenary powers as are necessary and desirable" to achieve the ALP's goals in domestic and international affairs. Labor also pledged to abolish the Senate; this goal was not erased from the party platform until 1979, after Whitlam had stepped down as leader.
