The Electrical Trades Union of Australia (ETU) is the industry body representing electricians in Australia. In 2022, it had over 30,000 members.
Established in 1912, the ETU is a division of the Communications, Electrical and Plumbing Union (CEPU), and is the largest of the three divisions.
Traditionally, the ETU has supported left- or centre-left political parties. However, in November 2019, the ETU ceased donations to the federal Labor party over Anthony Albanese's government supporting free trade agreements.
