Visa extension: do you need new OSHC or can you extend your existing policy?

A student visa extension changes the answer to a question most students never ask: does my health cover still run for long enough? Condition 8501 requires adequate cover for the whole of your stay. If your visa moves out by six months and your policy does not, you have a gap that is a compliance problem, not just an inconvenience.

The good news is that extensions are a normal, anticipated event in student health cover, and the OSHC Deed commencing 1 July 2025 has provisions for both the extra cover and its refund if the extension is refused.

Do you need new cover, or can you extend?

It depends on when the extension happens relative to your current policy end date.

If your policy already runs to or past the new visa expiry date — you are already compliant and do not need to do anything. This is the common case if you originally bought cover for a period longer than your first visa grant, which is a sensible habit precisely because extensions are frequent in Australian student visa pathways.

If your policy ends before the new visa expiry date — you need cover for the extension. In practice that means either extending the current policy with the same insurer, or taking a new policy that runs to the new expiry date. The Department of Home Affairs’ Student visa (subclass 500) page sets the visa terms, and your adequate health insurance guidance sets the cover requirement that has to match it.

The important word is match. Your cover has to run to your new expiry date, for you and for any family members on the visa. Our article on condition 8501 covers the compliance detail.

What if the extension is refused?

This is where the Dee’s refund schedule earns its keep. Schedule 5, row (d) covers it directly:

“The Overseas Student has paid the premium of an extended stay on the basis the Student Visa will be extended by Home Affairs but is refused an extension — Paid premium amount in relation to the extension to be refunded in full, less a reasonable processing fee (if any).”

So if you bought cover for the extended period in advance and the extension is then refused, the premium you paid for that extension is refundable in full, less a reasonable processing fee. That is the specific protection for the scenario where you commit to extra cover on the expectation of an extension.

A second row matters here too. Schedule 5, row (i) covers administrative changes that adjust the OSHC period beyond what the Student Visa actually requires, and provides a pro-rata refund for the affected period. So if the required cover period shrinks for administrative reasons, that is refundable as well.

Getting the timing right

Extensions have a rhythm, and cover needs to move with it:

1. Find your current policy end date and your current visa expiry date. They should be the same, or the policy should run past the visa.
2. Watch for the extension trigger. If your current policy does not cover you to the new expiry, act before the gap, not after.
3. Extend or re-buy to the new expiry date, and check that waiting periods are not restarted if you stay with the same insurer. Served waiting periods are credited where cover is continuous — see switching OSHC insurers.
4. Keep the paperwork aligned. Your policy certificate should show cover to the new expiry date.

Covering the extension with an insurer that is actually selling OSHC

One practical note: not every insurer that once sold OSHC still does. The insurers currently selling new OSHC are set out in who still sells student cover — Allianz Care Australia, Medibank, ahm, Bupa Australia and nib. If you are extending with an insurer you joined years ago, check they are still writing OSHC before you rely on them for the extension.

You can see the current insurers side by side on our comparison page, and get a live quote for your exact extended dates on our quote page. Allianz Care Australia, Bupa Australia, Medibank and ahm can be quoted and bought through our checkout; nib sells OSHC and we compare it, but we do not offer it for purchase. Insurers quote you directly for your dates, so the figure you see is the figure you pay.

Key takeaways

• Your cover has to run to your new visa expiry date. A policy that ends sooner is a gap.
• If your policy already runs past the new expiry, you are compliant and do not need to do anything.
• If the extension is refused, the extra premium is refundable in full under Schedule 5 row (d), less a reasonable processing fee.
• Administrative changes to the required period are pro-rata refundable under Schedule 5 row (i).
• Act before the gap. Confirm the insurer is still writing OSHC before you plan an extension around them.
