PSA General Secretary Stewart Little has extensive experience in the areas covered by the union. Stewart joined the PSA in 1995 when he worked in the NSW Parliamentary Library and Research Centre.

He has also worked as a Disability Support Worker before the sector was privatised by the previous Liberal National Government.

In 2016, Stewart was elected PSA General Secretary, winning a second term in 2021 and a third in 2025.

One of the first decisions he made as General Secretary was to pursue a pay rise for members in NSW schools, believing their low wages was due to gender bias towards a woman-dominated sector of the workforce. The PSA won this case, winning pay rises as high as 36 per cent for members.

Stewart has upped the union’s campaigning against privatisation, making it a key focus in the state election that removed a three-term conservative government that had sold billions in state assets to the private sector.

The PSA’s campaigning against privatisation has had positive results, notably in corrections, with two of the state’s three private prisons will be moved to state control.

He has improved the union’s focus on mental health in the often-stressful workplaces members are employed in.

In 2024, Stewart was elected Secretary of the CPSU (SPSF) Federal Branch.

He has also worked at the Police Association and the Amalgamated Metal Workers Union.

He has long been a passionate advocate for women in football.
