What is a CoE (Confirmation of Enrolment)?

What a CoE actually is

A Confirmation of Enrolment is an official document issued by a registered Australian education provider (a university, TAFE, or other CRICOS-registered institution) once you have accepted your offer and met the provider's enrolment requirements — most commonly, paying the required deposit or tuition instalment.

It confirms, formally and for immigration purposes, that you have a genuine, paid place in a specific course, starting and ending on specific dates. It's issued through PRISMS, the Australian government's system for tracking international student enrolments, which is how Home Affairs cross-checks a visa applicant's claimed enrolment against a real, provider-confirmed one.

A CoE is provider-specific and course-specific — if you're doing a package of courses (for example, an ELICOS English course followed by a degree, or a diploma followed by a bachelor's via credit transfer), you may be issued more than one CoE, one for each stage, sometimes from different providers.

When a CoE is issued

A CoE is issued after two things have happened: you've accepted your offer, and you've paid whatever deposit or initial payment the provider requires as a condition of enrolment — commonly the first tuition instalment, sometimes covering OSHC as part of the same payment depending on the provider's package.

How long it takes for the CoE to actually be issued once payment clears varies by institution. Some universities issue it within a few business days; others take longer, particularly during peak periods in the lead-up to the February intake when processing volumes across the sector are at their highest. If you haven't received your CoE within the timeframe your provider indicated, following up directly with the international student office is the right move rather than waiting indefinitely.

You cannot apply for a student visa without a CoE (or, for streamlined arrangements, its confirmed equivalent) — it's a required piece of evidence in the application, not an optional add-on.

What's on a CoE and why the dates matter

A CoE shows your name, the provider and course details, and — critically — a course start date and an expected course end date. These dates aren't cosmetic. They flow directly into two other parts of your application:

First, your visa application references these dates — the length of student visa typically granted aligns with your course duration as shown on the CoE (plus some standard additional time in many cases, though the exact rules depend on your course length and circumstances).

Second, your OSHC is generally arranged to cover the same period the CoE shows, start to end. Insurers price and structure OSHC policies around exactly this window, which is why OSHC is usually one of the first things arranged once the CoE lands, not something left until later.

Because of how tightly these dates are linked, getting your CoE dates right — and understanding they're not just a formality — matters more than most students expect going in.

What happens if your CoE changes

Circumstances change — you might defer your start, change course, extend your study period, or take a leave of absence partway through. In most of these situations, the education provider issues an updated or replacement CoE reflecting the new dates or details.

A changed CoE has knock-on effects. Your OSHC coverage period may need to be adjusted to match the new dates. And depending on the nature and timing of the change, it can also have implications for your visa — this is genuinely case-specific and depends on your visa conditions and where you are in your enrolment, which is exactly the kind of question a MARA-registered migration agent should weigh in on rather than assuming a change is automatically fine. On Migratio you describe your situation once and compare consultation fees from MARA-registered agents (comparing is free; consults are typically $150–$300 and you pay only if you book).

The general principle: treat any CoE change as something to flag and check, not something to quietly let happen in the background, because the visa and OSHC consequences aren't automatic and aren't always obvious from the university's side alone.

CoE vs offer letter vs enrolment confirmation

It's easy to conflate a CoE with other documents you receive during the application process, so it's worth being precise about the difference. An offer letter is what the university sends after assessing your application — it says "we'll take you" but doesn't confirm you've accepted or paid anything yet.

An acceptance or enrolment confirmation (terminology varies by provider) might be sent once you've formally accepted the offer, but this is still a step before the CoE in most cases — it confirms your intent, not your paid, government-registered enrolment status.

The CoE is the final, government-system document — issued via PRISMS, the one with a verifiable CoE number, and the one your visa application actually needs. If you're not sure which document you're holding, check for the CoE number and PRISMS reference; if it's not there, it's probably not your CoE yet.

What does CoE stand for and what does it do?

CoE stands for Confirmation of Enrolment. It's the official document issued through PRISMS by your Australian education provider confirming you're genuinely enrolled and have paid the required deposit. It's the core document your student visa application relies on, and it shows the course start and end dates that your OSHC and visa are both built around.

When do I get my CoE after accepting my offer?

Generally after you've paid the required deposit or first tuition instalment. Timing varies by institution — some issue it within days, others take longer, particularly during the busy pre-February intake period. Follow up with your provider's international student office if it's taking longer than they indicated.

Do I need a CoE to apply for a student visa?

Yes — a CoE (or its confirmed equivalent for certain streamlined arrangements) is required evidence for a subclass 500 student visa application. You can't lodge without it.

Can I get more than one CoE?

Yes, if you're doing a package of courses — for example, an ELICOS English course followed by a degree, or a diploma with credit transfer into a bachelor's — you may be issued a separate CoE for each stage, sometimes from different providers.

What happens to my visa if my CoE changes?

This depends on the nature of the change and your visa conditions, so it's genuinely case-specific rather than something with one universal answer. A MARA-registered migration agent can advise on the effect of a CoE change on your particular visa situation — on Migratio you describe your situation once and compare consultation fees from MARA-registered agents (comparing is free; consults are typically $150–$300 and you pay only if you book).

Does my OSHC need to match my CoE dates exactly?

OSHC is generally arranged to cover the same period shown on your CoE, since that's the period your visa application and enrolment relate to. If your CoE dates change, your OSHC coverage period typically needs to be adjusted to match.
