Boilermakers and Blacksmiths Society of Australia

The Boilermakers and Blacksmiths Society of Australia was an Australian trade union representing boilermakers and blacksmiths between 1965 and 1972.
It was established on 1 January 1966 with the amalgamation of the Boilermakers' Society of Australia and the Blacksmiths' Society of Australia. Though widely described as the formation of a new union, it inherited the industrial registration of the Boilermakers' Society. The union was associated with a "militant left-wing" group within the Metal Trades Federation.
It amalgamated with the Sheet Metal Working Industrial Union of Australia and the Amalgamated Engineering Union in 1972 and ceased to exist at that time; however, due to legal issues over the name of the new union, the successor Amalgamated Metal Workers Union was not registered until 1973.
