The Electoral Commission of South Australia (ECSA) is an independent agency dedicated to providing professional and impartial electoral services, ensuring fair and lawful participation in the democratic process for all South Australians. Established in 1907, ECSA has evolved from the State Electoral Department to a pioneering body in electoral administration, being the first globally to leverage computer technology for tasks like producing electoral rolls. Their primary responsibilities include conducting state and local council elections every four years, maintaining the electoral roll, and registering political parties.

ECSA also facilitates a range of fee-for-service elections for various organizations, ensuring adherence to established electoral practices and providing resources such as voter lists and guidance on voting processes. Additionally, the agency actively engages in community awareness initiatives to educate the public about the electoral system. With a commitment to continuous improvement in its services, ECSA is dedicated to enhancing the electoral experience for all electors in South Australia
