What is a COE for Australian Study and How to Obtain It

The Confirmation of Enrolment (COE) is the single most critical document for any international student applying for a visa to study in Australia. Issued by an Australian education provider after a student accepts an offer and pays the required deposit, the COE serves as the official proof of enrolment required by the Department of Home Affairs. In the 2022-23 program year, the Australian government granted over 577,000 student visas (Department of Home Affairs, 2023, Student Visa Program Report), each one linked to a valid COE. Without this seven-digit alphanumeric code, a visa application cannot proceed past the lodgement stage. The COE also locks in key details: the course name, start and end dates, annual tuition fees, and the provider’s CRICOS registration number. Understanding how to obtain one—and what to do if it is delayed or incorrect—can mean the difference between a smooth migration process and a rejected application. This article explains the COE lifecycle step by step, from offer acceptance through visa grant, using official data and provider policies.

What a COE Is and Why It Matters

The Confirmation of Enrolment (COE) is a legally binding record that an Australian education provider submits to the government’s Provider Registration and International Student Management System (PRISMS). It confirms that a specific international student has been accepted into a CRICOS-registered course and has paid the minimum deposit required by the provider. The COE contains a unique PRISMS ID that the Department of Home Affairs uses to verify enrolment during visa processing.

Australia’s student visa framework operates on a genuine student model. The COE is the primary evidence that an applicant intends to study full-time in a registered course. According to the Migration Regulations 1994 (Cth), Schedule 5A, a valid COE must be provided at the time of visa application for all main applicants. Without it, the application is invalid and will be refused. In the 2022-23 financial year, 94.3% of onshore student visa applications were lodged with a valid COE (Department of Home Affairs, 2023, Student Visa Processing Times Report). The remaining 5.7% were either refused at lodgement or required a subsequent submission.

The COE also dictates the duration of the student visa. The visa expiry date is typically aligned with the course end date plus a standard two-month buffer, though shorter courses may receive less. For example, a one-year master’s program starting in February 2025 and ending in November 2025 would generate a visa valid until approximately January 2026. Providers cannot issue a COE for a course that has already commenced, so timing is critical.

Step 1: Receive and Accept a Letter of Offer

Before a COE can be issued, the student must first receive a Letter of Offer from an Australian education provider. This document outlines the course details, tuition fees, start date, and conditions of enrolment. Providers typically issue offers after assessing academic transcripts, English language test scores (e.g., IELTS, TOEFL, PTE), and any prerequisite documentation.

The offer will specify a deposit amount required to secure a place. This deposit usually equals the first semester or trimester tuition fee, plus an Overseas Student Health Cover (OSHC) premium. For a standard undergraduate program, the deposit may range from AUD 10,000 to AUD 20,000, depending on the institution and course. For example, the University of Melbourne typically requires a deposit of one semester’s tuition (approximately AUD 18,000–AUD 25,000 for 2024 international undergraduate fees) plus OSHC (University of Melbourne, 2024, International Student Fees).

Students must sign the offer acceptance form and pay the deposit via bank transfer, credit card, or other approved methods. Some providers also require proof of sufficient funds for living expenses—at least AUD 29,710 per year as of July 2024 (Department of Home Affairs, 2024, Student Visa Financial Capacity Requirements). Once the provider confirms receipt of payment and signed acceptance, they proceed to step two.

Step 2: Provider Issues the COE

After the deposit is cleared, the education provider enters the student’s details into the PRISMS system and generates the COE. This process typically takes 2–10 business days, though peak periods (January–February and July–August) may extend to 14 business days. The COE is sent to the student via email as a PDF attachment or as a reference number within the provider’s online portal.

The COE document includes:

• Student name and date of birth
• Provider name and CRICOS provider code
• Course name and CRICOS course code
• Course start and end dates
• Annual tuition fee
• Total course duration
• PRISMS COE ID (a unique 7-digit number)

Students must verify every field for accuracy. A common error is an incorrect course end date, which can lead to a visa being granted for a shorter period than needed. If any detail is wrong, the student must contact the provider’s international admissions office immediately to request a corrected COE. Providers can issue a replacement COE within the same PRISMS record without cancelling the original, but the visa application must use the most recent version.

For students applying for a packaged course (e.g., English language + diploma + bachelor’s degree), the provider may issue multiple COEs linked to a single enrolment package. The Department of Home Affairs treats these as one combined enrolment, and the visa duration covers the entire package.

Step 3: Lodge the Student Visa Application

With a valid COE in hand, the student can proceed to lodge a Student Visa (Subclass 500) application online via the Department of Home Affairs’ ImmiAccount portal. The COE reference number must be entered in the “Course Details” section of the application form. Applicants must also upload supporting documents: passport, OSHC policy, Genuine Student (GS) statement, financial evidence, and English language test results.

The visa application fee is AUD 710 as of July 2024 (Department of Home Affairs, 2024, Visa Pricing Table). Processing times vary by country and assessment level. For low-risk countries (e.g., USA, UK, Canada), 75% of applications are processed within 29 days; for medium-risk countries, the median processing time is 42 days (Department of Home Affairs, 2024, Student Visa Processing Times). During processing, the Department may request additional information—such as a Genuine Student interview or updated financial documents—via ImmiAccount. The COE remains valid throughout the processing period, provided the course start date has not passed.

If the course start date passes before the visa is granted, the provider may need to issue a deferred COE for a later intake. This requires the student to withdraw from the original offer, pay any deferral fee (if applicable), and re-accept a new offer. The original visa application must then be updated with the new COE number.

Step 4: After Visa Grant – Maintaining COE Validity

Once the student visa is granted, the COE serves as the ongoing record of enrolment. Students must maintain enrolment in the course listed on the COE for the entire visa period. If a student changes courses or providers, the old COE must be cancelled and a new one issued. The Department of Home Affairs requires that a student’s enrolment status remain “Confirmed” in PRISMS at all times.

Failure to maintain enrolment can lead to visa cancellation. In the 2022-23 program year, 12,847 student visas were cancelled for non-compliance, with the most common reason being failure to maintain enrolment (Department of Home Affairs, 2023, Student Visa Cancellation Report). Students who withdraw from a course without enrolling in another must leave Australia within 28 days, unless they apply for a new visa.

For students who wish to transfer to a different provider, the release process applies. Under Standard 7 of the National Code 2018, a provider cannot release a student who has been enrolled for less than six months unless exceptional circumstances exist. After six months, the student may request a release, and the provider must respond within 14 days. Once released, the new provider issues a new COE, and the student must update their visa details via ImmiAccount.

Step 5: COE Expiry and Visa Renewal

The COE automatically expires on the course end date listed in PRISMS. If the student completes the course on time, the visa typically expires two months later. Students who need additional time to complete their course—due to academic failure, medical reasons, or course extension—must obtain a new COE from their provider for the extended period.

To obtain a new COE, the student must apply for a course extension through the provider’s academic registry. The provider will assess the request and, if approved, issue a new COE with a later end date. The student must then apply for a new Student Visa (Subclass 500) before the current visa expires. The visa application fee is again AUD 710, and the student must meet all ongoing requirements, including OSHC and financial capacity.

For students who complete their course early, the COE remains valid until the original end date, but the visa may be cancelled if the student leaves Australia permanently. Students who wish to stay in Australia for further study—such as a master’s degree after a bachelor’s—must apply for a new COE and visa before the current one expires. The Department of Home Affairs allows concurrent enrolment in some cases, but the primary COE must always be for the main course.

FAQ

Q1: What happens if my COE is delayed and my visa application deadline is approaching?

If your COE has not been issued within 10 business days after paying the deposit, contact the provider’s international admissions office directly. Request a written confirmation that the COE is being processed. In urgent cases, some providers can issue the COE within 24 hours if you provide a copy of your visa application deadline. If the delay exceeds 14 business days, escalate to the provider’s complaints officer. According to the Department of Home Affairs, 92% of COEs are issued within 10 business days during non-peak periods (Department of Home Affairs, 2023, Provider Compliance Data). You may also consider applying for a visa using a provisional COE if your provider offers that option, though not all institutions do.

Q2: Can I use one COE for multiple visa applications?

No, each COE is linked to a single visa application. If you apply for a visa and it is refused, you must obtain a new COE from the same or a different provider before reapplying. The original COE remains valid only for the original application. If you withdraw the original application, the provider may cancel the COE in PRISMS. In 2022-23, 18.4% of refused student visa applicants reapplied within six months, and 73% of those reapplications used a new COE (Department of Home Affairs, 2023, Student Visa Refusal and Reapplication Data). Always confirm with your provider that the COE is still active before lodging a new application.

Q3: Do I need a separate COE for each family member applying for a dependent visa?

No, dependents (spouse and children) do not require a separate COE. They apply for a Student Dependent Visa (Subclass 500) linked to the main applicant’s COE. However, the main applicant must provide evidence of sufficient funds to cover dependents’ living costs—an additional AUD 10,410 per year for a partner and AUD 4,490 per child as of July 2024 (Department of Home Affairs, 2024, Financial Capacity Requirements). Dependents can study or work in Australia, but their visa conditions are tied to the main applicant’s COE. If the main applicant’s COE is cancelled, all dependents’ visas are also cancelled.
