Transport Workers' Union of Australia

The Transport Workers' Union of Australia (TWU) is a trade union representing workers in various transport sectors. It has five main branches, covering the Australian Capital Territory/New South Wales, Queensland, Victoria/Tasmania, South Australia/Northern Territory, and Western Australia. The TWU's primary focus areas include road transport, commercial aviation, and more recently, gig economy workers.

The TWU is a progressive union based on the organising model. The TWU is affiliated with the Australian Council of Trade Unions and the International Transport Workers' Federation. In South Australia, Queensland and New South Wales, the union is affiliated with the Labor Right. The TWU is considered to be one of the most powerful unions in the Labor Right faction of the Australian Labor Party.

The history of the Transport Workers' Union is partly a story of the technological and economic changes to the ways people and goods have been transported across the history of Australia. Its main beliefs are that the free market cannot be relied upon to create a safe, efficient and viable transport industry, and that transport workers should stand together to strive for better pay and conditions.
