The Constitution Alteration (Industrial Matters) Bill 1912,[1] was an unsuccessful referendum held in 1913 that sought to alter the Australian Constitution to give the Commonwealth legislative power in respect to industrial matters.

The proposal was to alter the text of section 51 of the Constitution to read as follows:[2] 51.

The Parliament shall, subject to this Constitution, have Legislative power to make laws for the peace, order, and good government of the Commonwealth with respect to: (xxxv.)

Conciliation and arbitration for the prevention and settlement of industrial disputes extending beyond the limits of any one State: The 1911 referendum asked a single question that dealt with trade and commerce, corporations and industrial matters.

On each of the many occasions a similar question was asked at a referendum the public decided not to vest power in the Commonwealth over these matters.
