Should you use OSCA or ANZSCO?
OSCA 2024 is the current Australian occupation classification for storing, organising and reporting occupation information. Use this OSCA record for current Australian statistical and analytical classification work.
Some migration and administrative programs still specify ANZSCO 2022. Check the exact system named by the agency or form rather than replacing the code automatically.
