The Australian Timber Workers' Union was registered in 1918 after the deregistration of the Amalgamated Timber Workers' Union of Australia. The new union extended coverage to workers in box and case factories, saw makers' shops, joiners' workshops, carpenters, implement workers and wood working machinists. In 1940 the union filed an application and succeeded in extending its coverage to most workers employed in the timber and wood industry including cabinet makers and furniture factories. In 1991 it amalgamated with the Pulp & Paper Workers' Federation of Australia to form the Australian Timber & Allied Industries Union. Later in the year another amalgamation with the Building Workers' Industrial Union of Australia created the ATAIU & BWIU Amalgamated Union. Further amalgamations eventually saw this union become part of the Construction Forestry Mining & Energy Union in 1993.
