Confirmation of Enrolment (CoE) for an Australian Student Visa Explained (2026)

If you've researched the US or UK process, you've seen the equivalent documents already, the I-20 and the CAS. Australia's version is the Confirmation of Enrolment, or CoE, and it's genuinely easy to confuse with the Letter of Offer that comes before it, especially since both documents can look similar and arrive within weeks of each other. Since 1 January 2025 that confusion has gotten more consequential: a Letter of Offer alone no longer satisfies a Subclass 500 student visa application, and an application without a valid CoE number for every intended course can be treated as invalid outright. This post covers what a CoE actually is, how it differs from the offer that precedes it, and the regulatory change that makes getting this right matter more than it used to.

What a CoE actually is, and what it isn't

A Confirmation of Enrolment is an official document issued by an education provider registered on CRICOS, the Commonwealth Register of Institutions and Courses for Overseas Students, confirming that you've accepted a place in a specific eligible course. It's not the same thing as your initial Letter of Offer. The sequence runs in order: a provider sends a Letter of Offer describing the course and its conditions, you accept that offer and typically pay a deposit or your full tuition fees, you arrange and pay for Overseas Student Health Cover (OSHC), and only once those steps are satisfied does the provider issue the CoE itself. The CoE document lists your specific course details, the official CRICOS course code, your provider's details, start and end dates, any fees already paid, and your estimated total fees still owed. It's the document the Department of Home Affairs actually requires as evidence before a Subclass 500 visa can be granted, not the earlier offer letter.

The 1 January 2025 change that raised the stakes

Before this date, some applicants, particularly those applying onshore, could lodge a Subclass 500 application using a Letter of Offer alone, finalizing the CoE afterward. That's no longer the case. A Migration Regulations amendment instrument, F2024L01728, commencing 1 January 2025, sets out that an application for a Subclass 500 visa must be accompanied by evidence of your intended course of study specifically including a confirmation of enrolment number, one that hasn't been cancelled or revoked, for each of your intended courses of study. Migration-law sources describe this change as applying to both onshore and offshore applicants, explicitly aligning the two groups under the same requirement, and as closing off the option of lodging with only a Letter of Offer. Applying without a valid CoE number for each course now risks the application itself being treated as invalid, a materially worse outcome than simply being asked to supply a missing document later.

Practically, this means you shouldn't lodge your visa application the moment you receive a Letter of Offer. Wait until your provider has actually issued the CoE, confirm the CoE number is current and hasn't lapsed, and enter it correctly in ImmiAccount for every course your enrolment covers before you submit.

How the CoE connects to PRISMS, and why that matters if your plans change

Providers don't issue CoEs manually; they run through PRISMS, the government's Provider Registration and International Student Management System, which administers compliance under the ESOS Act (the Education Services for Overseas Students Act). Only staff with specific CoE Administrator access at a provider can actually create and approve a CoE; other staff may be limited to preparing one for that approval. This matters to you mainly because it means a provider can also cancel or revoke a CoE through the same system, for reasons like non-payment of fees, a formal transfer between courses, or a deferral of your start date, and the regulation specifically requires the CoE number on your visa application to be one that hasn't been cancelled or revoked. If anything about your enrolment changes while a visa application is pending, confirm directly with your provider's international office that your CoE is still valid, rather than assuming it automatically carries forward.

Packaged courses likely need more than one CoE

If your enrolment is packaged, for instance an English-language or foundation program bundled ahead of your actual degree, the regulation's own wording, a CoE number for each of your intended courses of study, points toward needing a separate CoE for each component rather than one document covering the whole package. We didn't find official guidance spelling out the packaged-course mechanic in more granular detail than that regulatory language, so this is worth confirming directly and specifically with your provider's international student office: how many CoEs does your particular enrolment generate, and are all of them correctly listed in your visa application. Missing one CoE from a multi-course package is an easy, avoidable mistake given how the requirement is written.

What the CoE says about your fees, and why that matters if you're partly funded

A CoE isn't just a status document, it's also a financial record of your specific enrolment, listing fees you've already paid and your estimated total fees still owed for the course. That matters directly if you're relying on a scholarship, a university assistantship, or a professor-funded research position to cover some or all of your tuition rather than paying out of pocket. Before you accept the figures a CoE states, confirm with your provider's international or finance office that any scholarship, fee waiver, or assistantship you've been promised is actually reflected in the fees-paid and fees-owed figures the CoE shows, rather than assuming it will be applied automatically after the document is issued. A CoE that understates what you've genuinely secured in funding can create a mismatch between what the visa application implies you can pay and what you're actually relying on to cover the course, which is worth catching and correcting with the provider before you lodge your visa application, not after.

The CoE is separate from the Genuine Student requirement

It's worth being precise about what the CoE does and doesn't cover, because Australia's Subclass 500 process layers more than one requirement into the same application. Our guide to Australia's Genuine Student requirement covers the separate test that replaced the old Genuine Temporary Entrant criterion on 23 March 2024, a written, assessed demonstration of your genuine intention to study, distinct from any single document. The CoE isn't part of that assessment; it's a factual record that you've accepted and paid for a specific, CRICOS-registered course. You need both: a CoE confirming your enrolment, and a Genuine Student statement and supporting evidence satisfying the separate intent criterion. Confusing the two, or assuming a strong CoE substitutes for a weak Genuine Student case, is a mistake worth avoiding.

What this means for your own timeline

Build in the real sequence rather than assuming it moves faster than it does: offer, acceptance and payment, OSHC arrangement, then CoE issuance, and only then a valid visa application. If you're also working through finding a PhD supervisor in Australia, remember that a supervisor's agreement to take you on doesn't itself generate a CoE, your formal enrolment and fee arrangements with the university do, so leave time between an admission decision and your intended start date for the enrolment and payment steps to actually complete.
