Members of the AEU include teachers and allied educational staff, principals and administrators mainly in government school and TAFE systems. Membership in South Australia is currently around 14,000.
The AEU represents its members industrially and professionally in diverse forums. This includes the maintenance of comprehensive industrial protection and representation through industrial awards and agreements in all industrial tribunals in Australia. This involves industrial research, negotiation and advocacy over a wide range of matters including salaries and teaching and learning conditions. As the largest union in the education sector, the AEU is an effective lobbyist for educational resources at both Commonwealth and state levels. Through the Federation of Education Unions, the AEU works closely with the two other Federal unions which cover educators in non-government schools and universities.
