OSCA vs ANZSCO: Which Occupation List Rules Your Visa
OSCA vs ANZSCO for Australian visas: ANZSCO remains the operative occupation classification for migration. Here is what that means for your nomination.
If you are researching an Australian skilled or employer-sponsored visa, you may have seen references to both OSCA and ANZSCO and wondered which one your application uses. The short answer: ANZSCO remains the operative occupation classification for migration. As at June 2026, the Department of Home Affairs has not adopted OSCA for visa purposes, so your occupation is still classified by its ANZSCO code.
Using the wrong classification can lead to a refusal. Choosing the wrong code, or assuming a new classification governs your case when it does not, can lead to a refused nomination or a visa application that never gets off the ground.
What OSCA and ANZSCO actually are
ANZSCO stands for the Australian and New Zealand Standard Classification of Occupations. It is the system that has underpinned Australia’s skilled migration occupation lists for years. Every occupation carries an ANZSCO code and a set of typical duties, and the migration occupation lists are built around those codes.
OSCA stands for the Occupation Standard Classification for Australia. It is a newer occupation classification released by the Australian Bureau of Statistics to modernise how occupations are described for statistical purposes. Because it is more current in some respects, it is easy to assume it has quietly replaced ANZSCO everywhere. It has not, at least not for migration.
Why ANZSCO still governs your visa
The occupation lists that drive skilled and employer-sponsored visas are defined by legislative instruments and by the codes in ANZSCO. For migration, the Department continues to classify occupations by ANZSCO code. Until the Department formally adopts a different classification for visa decision-making and updates the relevant instruments, ANZSCO is what counts.
This is a point where confident-sounding but inaccurate information circulates online. Some commentary treats OSCA as though it is already the operative classification for visas. It is not. If a source tells you your visa occupation is now assessed under OSCA, treat that as incorrect and verify it against the primary source at immi.homeaffairs.gov.au.

Where the occupation code bites
The occupation classification is not a background detail. It shapes several parts of your application.
- Eligibility. Your nominated occupation must appear on the occupation list that applies to your visa subclass. For the Subclass 482 Skills in Demand visa, the Core Skills stream draws on the Core Skills Occupation List, while the Specialist Skills stream operates on a different basis. For the Subclass 186 Employer Nomination Scheme, the Direct Entry pathway also relies on the relevant occupation list.
- Duties matching. It is not enough for a job title to sound like your occupation. Your actual duties must fit the description behind the ANZSCO code. Case officers look at what you will really do, not just the label.
- Skills assessment. Many visas require a positive skills assessment, and the assessing authority assesses you against a specific occupation code. If the code is wrong, the assessment can be wrong too.
Because the occupation lists are set by legislative instruments and can be revised, you should always confirm that your occupation is currently listed for your intended subclass at the time you lodge. Lists change, and a revised occupation list is anticipated during 2026. Re-check before you rely on it.
Getting your occupation code right
A few practical steps reduce the risk of a code error derailing your application.
- Start from the duties, not the title. Map your real, day-to-day responsibilities against the ANZSCO occupation descriptions, then find the code that genuinely fits.
- Check the current occupation list. Confirm the occupation appears on the list that applies to your specific subclass and stream, using the Department’s published material as your source.
- Line up your skills assessment. Make sure the occupation you assess under matches the occupation you nominate.
- Watch for list revisions. Because the migration occupation lists are updated by instrument, a code that is valid today may sit differently after a revision. Timing can matter.

The takeaway
OSCA is a real and evolving classification, but for now it is a statistical tool, not the yardstick for your visa. Your Australian skilled or employer-sponsored application is still classified by ANZSCO code. If any figure, list, or classification is central to your decision, confirm it against the Department of Home Affairs and the Federal Register of Legislation at the time you act, because these details change.
Getting the occupation classification right at the start is one of the cheapest ways to protect an application that may span years and significant cost. It is far easier to choose the correct code before lodgement than to unwind a refusal afterwards.
