Does OSCA or ANZSCO rule your visa occupation?

Anyone researching an Australian skilled or employer sponsored visa will meet references to both OSCA and ANZSCO and may wonder which one governs the application. 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 an occupation is still classified by its ANZSCO code.

The distinction has consequences. The occupation code nominated determines which list applies, which visa pathway is open, and the standard the work will be measured against. Choosing the wrong code, or assuming a new classification governs a case when it does not, risks a refused nomination or a visa application that cannot proceed.

What OSCA and ANZSCO are

ANZSCO stands for the Australian and New Zealand Standard Classification of Occupations. It 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 replaced ANZSCO everywhere. For migration, it has not.

The two systems can classify the same job differently. They split, merge and rename occupations in ways that do not line up code for code, so reading an OSCA description, finding the closest ANZSCO equivalent and treating the two as interchangeable is unsafe. For a visa, only the ANZSCO code and its duties are operative, and that description is the one the case will be judged against.

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. The Department continues to classify occupations by ANZSCO code for migration. Until the Department formally adopts a different classification for visa decision-making and updates the relevant instruments, ANZSCO is what counts.

Confident but inaccurate information circulates on this point. Some commentary treats OSCA as though it were already the operative classification for visas. Any source that says a visa occupation is now assessed under OSCA should be treated as incorrect and checked against the primary source at immi.homeaffairs.gov.au.

Our OSCA page sets out the classification question in plain English.

Where the occupation code bites

The occupation classification shapes several parts of an application.

• Eligibility. The nominated occupation must appear on the occupation list that applies to the 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. A job title that sounds like the occupation is not enough. The actual duties must fit the description behind the ANZSCO code, and case officers look at what the person will do rather than the label.
• Skills assessment. Many visas require a positive skills assessment, and the assessing authority assesses the applicant 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, confirm that the occupation is currently listed for the intended subclass at the time of lodgement. Lists change, and a revised occupation list is anticipated during 2026. Re-check before relying on it.

The task match is decided independently, not certified

The most misunderstood part of occupation coding is who decides whether the match holds. A sponsor may believe in good faith that a role fits a nominated occupation, and may say so in the nomination. That belief is not the test. The decision-maker forms an independent view of whether the tasks of the position correspond to the nominated occupation, and a sponsor’s certification does not settle the question.

The Federal Court made this plain in Cargo First Pty Ltd v Minister for Immigration and Border Protection [2016] FCA 30. The Court accepted that the decision-maker must independently assess whether a significant majority of the tasks of the nominated position match the tasks of the nominated occupation. A sponsor’s assertion that the position corresponds to the occupation is not conclusive; the delegate is entitled, and required, to look at the substance of the role and reach their own conclusion.

A code can look right on paper and still fail if the day-to-day tasks do not line up with the occupation behind it. A plausible but loosely fitting code does the most damage here. It survives the first glance and passes internal review, then does not withstand the decision-maker’s own analysis of what the person will do. The nominated occupation is a statement about the work, and that statement is tested against a significant majority of the actual tasks, not against a job title chosen to fit a list.

Stretching to reach a listed occupation is therefore a poor strategy. If the genuine duties sit outside a listed occupation, coding into a listed one the person does not perform does not solve the eligibility problem. It moves the risk from a visible mismatch on the list to a hidden mismatch on the tasks, which a careful decision-maker is entitled to find. The stronger position is a code that reflects the real role, supported by a position description and evidence showing the tasks matching the occupation.

Getting your occupation code right

Several steps reduce the risk of a code error derailing an application.

1. Start from the duties, not the title. Map the real, day-to-day responsibilities against the ANZSCO occupation descriptions, then find the code that fits. Work from the tasks a decision-maker would see, because those are what the match is measured against.
2. Check the current occupation list. Confirm the occupation appears on the list that applies to the specific subclass and stream, using the Department’s published material as the source.
3. Line up the skills assessment. Make sure the occupation assessed matches the occupation nominated, so the two do not contradict each other.
4. Document the task match. Build a position description and supporting evidence that show a significant majority of the tasks corresponding to the nominated occupation, rather than relying on a certification alone.
5. 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.

Where this leaves an applicant

OSCA is a real and evolving classification, but for now it is a statistical tool rather than the yardstick for a visa. An Australian skilled or employer sponsored application is still classified by ANZSCO code, and that code is only as strong as the task match behind it. Where any figure, list or classification is central to a decision, confirm it against the Department of Home Affairs and the Federal Register of Legislation at the time of acting, because these details change.

Choosing the correct code, and building the evidence that supports it, before lodgement is far easier than unwinding a refusal afterwards.
