Data transparency

About ANZSCOCODE & our sources

How occupation information is sourced, what “ABS verified” means, and why migration information is kept separate from statistical classification data.

How the data is organised

Occupation reference and migration reference are separate

ANZSCO occupation descriptions and skill levels come from the Australian Bureau of Statistics. Assessing authorities and skilled-visa occupation-list rules are migration-specific information and come from Department of Home Affairs instruments.

ABS occupation reference

ANZSCO code, principal title, occupation lead statement, skill level, alternative titles and specialisations.

Migration reference

Assessing authority, occupation-list and visa applicability. These can change independently of ABS classification data.

ANZSCO vs OSCA

Why this site still uses ANZSCO

ABS introduced OSCA 2024 as Australia's current statistical occupation classification. Australian migration programs can continue to reference ANZSCO versions, so ANZSCO remains important for skilled migration research. ANZSCOCODE keeps that distinction visible instead of treating the two classifications as interchangeable.

Verification

What “ABS verified” means

The ANZSCO 2022 occupation reference dataset used on this site was checked against ABS occupation definitions. The current occupation description and skill-level dataset was verified on 23 September 2026. Migration-specific fields should be checked against the latest Home Affairs legislative instruments because they are maintained separately.
