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.

Frequently asked questions
What does OSCA 311532 do?
Earth Science Technician is the current ABS occupation record used to describe a specific occupation. It sits in the OSCA hierarchy and carries skill-level context plus related titles and tasks.
How should I read the skill level?
The skill level tells you the educational or training depth that the ABS associates with the occupation. It is a classification signal, not a salary band or a qualification checklist on its own.
Why is industry context shown on an occupation page?
Industry context helps when the title is common or ambiguous. It shows where the occupation is typically employed so you can compare it with the right ANZSIC family.
