AACA, the Architects Accreditation Council of Australia, serves as the national voice for architect registration boards across Australia. Established in the 1970s, this not-for-profit organization aims to provide a nationally consistent approach to eligibility for registration and recognition of overseas qualifications in architecture. One of their key assets is the National Standard of Competency for Architects, which forms the foundation for all assessment processes, including the accreditation of architecture programs leading to registration as an architect in Australia.

AACA fulfills various roles both locally and internationally. Locally, they consult with key organizations, develop and promote the National Standard, and administer competency-based assessment programs. Internationally, they facilitate mutual recognition agreements on architectural education and registration, assess overseas qualifications, and provide accurate data on the architecture profession in Australia and overseas.

AACA collaborates closely with state and territory architects registration boards, the Australian Institute of Architects, associations of consulting architects, Australian schools of architecture, and Commonwealth Government departments. Their board of directors consists of experienced professionals from the architectural field who bring valuable expertise and knowledge to the organization. Overall, AACA plays a pivotal role in maintaining high standards in the architecture profession, ensuring the public's confidence, and supporting architects in their journey towards registration and practice in Australia
