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.

How to use this occupation page
Start with the official OSCA title and task list. Then confirm the parent unit group and compare the related occupations on this page if the job title is broad, overlapping or used differently across employers.
The ANZSIC links are there to help when the same occupation appears across several industries and you need the business-side classification as well.
