DIAC introduces ANZSCO on 1 July 2010

Australian and New Zealand Standard Classification of Occupations (ANZSCO) is a system developed to collect, publish and analyse occupation statistics across government agencies, and is being introduced by the department as the new standard to capture occupation information in all visa, settlement and citizenship programs.

ANZSCO will also be used within skilled visa programs, where it is a requirement for visa eligibility, as the standard by which a visa applicant's skills to undertake a specific occupation in Australia are assessed.
