Frequently asked questions
What does OSCA 369933 do?
Waterproofer 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.
