How to Switch Health Insurance Funds in Australia

What you need to know before switching

Switching health funds is more straightforward than most people expect, but there are three important rules to understand before you start.

The 2-month rule: You must join your new fund within 2 months of leaving your previous fund for waiting periods to be recognised. A gap longer than 2 months means you may need to re-serve waiting periods from scratch. This is the most critical thing to get right.

Waiting periods carry over for equivalent cover: If you switch to the same or lower level of cover, your new fund must legally recognise the waiting periods you have already served. You do not start from zero.

Annual extras limits carry over too: Any extras benefits you have already claimed in the current calendar year with your old fund count toward your annual limits with the new fund. Your remaining limit for the year is adjusted accordingly. Most funds reset annual limits on 1 January, though some use a financial year basis -- always check before switching.

Step by step: how to switch funds

Compare your current policy against alternatives

Use our compare tool to find policies at the same tier level with better pricing or inclusions. Staying at the same or lower tier protects your waiting period history.

Check your current waiting period and annual limit status

Contact your fund or log into your member portal to get a waiting period clearance summary and see how much of your extras annual limits you have used this year.

Join your new fund before leaving the old one

Sign up with your new fund while still covered by your old one. You must join within 2 months of leaving to have waiting periods recognised. Never cancel first.

New fund requests your transfer certificate

Your new fund contacts your old fund to request a transfer certificate confirming your waiting period history. You generally do not need to manage this -- the new fund handles it within 14 days.

Cancel your old policy

Once new cover is confirmed active, contact your old fund to cancel in writing. Get written confirmation of the cancellation date and check whether you are owed a refund of prepaid premiums.

Confirm waiting period status with your new fund

Ask your new fund to confirm in writing which waiting periods have transferred and what you are currently eligible to claim. Keep this document.

What happens to your waiting periods

Under the Private Health Insurance Act, if you switch to the same or lower level of cover within 2 months, your new fund must recognise all waiting periods you have already served.

Upgrading your cover while switching

If you move to a higher tier or add new clinical categories, new waiting periods apply only to those specific new inclusions. Your existing clearances remain in place for everything you were already covered for.

Extras annual limits when switching

Claims you have already made with your old fund this calendar year carry over to your new fund. If you claimed $300 toward dental with your old fund and your new policy has a $500 annual dental limit, you can only claim $200 more this calendar year with the new fund. This resets on 1 January for most funds.

Some funds reset annual limits on a financial year basis (1 July) rather than a calendar year. ahm is one example. Check this before switching, especially if you are mid-year and have already claimed significantly.

Best time to switch

Premium increases take effect on 1 April each year. This is the best time to review your cover. Switching before 1 April means you avoid the increase from your old fund. Many funds also run joining incentives in February and March to attract switchers, including waived extras waiting periods and free months of cover.

Some funds allow you to prepay your annual premium at the current rate before 1 April to lock in the price for another year. If you plan to stay, ask your fund whether this option is available.

Pre-switch checklist

I have confirmed the new policy is at the same or lower tier as my current cover

I have checked all clinical categories I currently use are included in the new policy

I have confirmed my current waiting period status with my existing fund in writing

I have checked how much of my annual extras limits I have used this year

I have joined the new fund and received confirmation that my cover is active

I am not in the middle of a claim, hospital admission, or ongoing treatment

I have confirmed whether I am entitled to a refund of prepaid premiums from my old fund

I have asked my new fund to confirm transferred waiting periods in writing

Common switching mistakes

Cancelling your old policy before new cover is active, creating a gap and potential MLS liability
Leaving more than 2 months between policies, forcing you to re-serve waiting periods
Switching to a lower tier to save money without realising it removes cover for upcoming planned treatment
Not checking whether your preferred hospital or specialist is in the new fund's network
Switching mid-year without accounting for used extras annual limits carrying over
Not getting written confirmation of the cancellation date from your old fund

Never cancel your old policy over the phone without written confirmation of the cancellation date. Verbal cancellations can be disputed and you may end up being charged for both policies.

Did your fund mishandle your switch?

If your previous fund refused to issue a transfer certificate, applied incorrect waiting periods, or charged you after cancellation, you have rights. DisputeSmart can help you navigate the complaint process.
