The short answer
The best time to switch health insurance is whenever you find a better-value policy for your situation — but the two windows where switching is most worthwhile are March/early April (before the annual premium rise lands on 1 April) and the weeks before a major life change (turning 31, getting married, having a baby, kids leaving the policy).
You don't have to wait for the new financial year. Health funds let you switch any day of the year, and a properly executed switch keeps every waiting period you've already served.
Why March and early April are the busiest switching window
Every year, funds raise premiums on 1 April. Increases vary a lot — in 2026, the industry average was 4.41%, but individual funds ranged from 1.98% to 5.98%. If your fund is going up more than the average, switching to a fund with a smaller increase can save hundreds without changing your cover at all.
Funds also publish their 2026 rates from late February, which is when comparing makes the most sense. By April, the new prices are live and any saving you'd have locked in by switching earlier is already eaten by the higher premium.
Other good times to switch
Before you turn 31
If you don't hold hospital cover by 1 July after your 31st birthday, you'll pay Lifetime Health Cover (LHC) loading — 2% extra on premiums for every year you delayed, up to 70%. Getting any tier of hospital cover before that deadline avoids the loading entirely.
Before a baby
Pregnancy and birth cover sits on Silver tier or higher and has a 12-month waiting period. If a baby is on the cards, switch to a policy that includes obstetrics at least 12 months before the due date.
After a life change
Getting married, moving in together, having kids leave the policy, or retiring all change what cover is right for you. Singles cover after a divorce, or downgrading from Gold to Silver Plus once kids are off the policy, often saves $1,500–$3,000 a year.
When switching isn't worth it
If you're mid-treatment, mid-pregnancy, or about to claim something with a long waiting period that you've already served on your current cover, double-check with an advisor before you switch. Equivalent cover transfers waiting periods, but only for benefits the new policy actually includes.
Frequently asked questions
- Will I lose my waiting periods if I switch funds?
- No — any waiting period you've already served on equivalent cover transfers to your new fund. You only re-serve waiting periods on benefits your new policy includes that your old one didn't.
- Do I have to wait until 1 April to switch?
- No, you can switch any day. Most people switch in March because it locks in the lower premium before the annual increase hits.
- Will my old fund charge a cancellation fee?
- Australian health funds don't charge cancellation or exit fees. The new fund organises the switch and refunds any unused premium from the old fund.
