The SDA has a history of campaigning across the broader union movement. It was the biggest financial contributor to unions in the 1998 Australian waterfront dispute and the 'Your Rights At Work' campaign, which is credited with overturning John Howard's WorkChoices laws. It continues this tradition today through its contribution to the ACTU's Change The Rules campaign focused on reforming Australian industrial relations in the lead up to the 2019 federal election. The SDA was led for 36 years from 1978 to 2014 by National Secretary Joe de Bruyn.
