The AWU affair refers to allegations of embezzlement via a fund established for the AWU Workplace Reform Association in the early 1990s by Bruce Wilson and Ralph Blewitt, officials of the Australian Workers' Union (AWU). Wilson and Blewitt raised $400,000 from major construction companies, and have been accused of using the funds for personal benefit, including diverting funds for the purchase of a house in Fitzroy.

The Australian Workers' Union (AWU) is one of Australia's largest and oldest trade unions. It traces its origins to unions founded in the pastoral and mining industries in the late 1880s and it currently has approximately 80,000 members. It has exercised an outsized influence on the Australian Trade Union movement and on the Australian Labor Party throughout its history.
