ASPA - the Australian Secondary Principals Association - is the umbrella organisation for the eight state and territory associations of government secondary school leaders. Members of the state and territory associations are automatically members of ASPA, and their local association pays annual affiliation fees to ASPA. There are about 2,000 members across all states and territories.

ASPA works in the national educational scene with the Commonwealth Government, DEST, and the many and various government agencies that administer policies and projects in which ASPA has an interest.

ASPA has close working relationships with the other peak associations of school leaders,both nationally and internationally.
