When it comes to private health insurance in Australia, understanding the rules around backdating and waiting periods can help you avoid unexpected costs and make better decisions for you and your family. Below are the key points you need to know.
1. Backdating Rules
Australian private health insurance strictly prohibits backdating claims for treatments that occurred before the policy start date. This means:
- Newly purchased policies will not cover treatments completed before the coverage commenced.
- Policy upgrades only apply to treatments performed after the upgrade date.
- The only exception: Newborn or adopted children can be added to a family policy with backdated coverage from their date of birth (must be done within 2–3 months of birth or adoption).

2. Waiting Periods Explained
Waiting periods exist to prevent people from taking out insurance only when they need immediate treatment. These vary depending on the type of cover:
Hospital Cover Waiting Periods
- Accidents: Usually 1 day (some insurers may waive this).
- New illnesses: 2 months (provided there were no symptoms within 6 months before joining).
- Pre-existing conditions: 12 months.
- Pregnancy and birth-related services: 12 months (cover must extend until the delivery date).
Extras Cover Waiting Periods
- Basic dental and physiotherapy: 2 months.
- Optical (glasses/contact lenses): 2–6 months (varies by insurer).
- Major dental/orthodontics: 12 months or longer.
Tip: Some insurers offer waiting period waivers as part of promotions for new members. Always check for the latest offers before signing up.
3. Switching Health Insurance Providers
Under Australia’s portability rules, you can switch health funds without losing certain waiting period benefits, but there are key considerations:
- Completed hospital waiting periods will carry over to the new policy.
- Continuous coverage is essential—most health insurers offer a grace period between canceling your old policy and starting the new one.
- Extras cover waiting periods may need to be recalculated, depending on the new insurer’s rules.
Important: If you upgrade your cover, any new services added through the upgrade will still require the standard waiting periods.
Frequently Asked Questions (FAQs)
Q: Can I claim for treatments that occurred before I bought insurance?A: No. Claims are only eligible for treatments completed after the waiting period and while your policy is active.
Q: Will switching insurers reset my waiting periods?A: Hospital cover waiting periods will not reset, but extras cover may vary. However, Hippo Wealth clients may enjoy exclusive benefits, such as waiting period waivers or free premium weeks, through partner promotions.
Q: Can newborn insurance be backdated?A: Yes. Most insurers allow backdating to the date of birth, provided you add the child to your policy within 2–3 months of birth.
