Medicare vs Private Health Insurance: What's the Difference?
Many Australians wonder whether they need private health insurance when Medicare already provides substantial health cover. The answer depends on your circumstances, healthcare needs, and financial situation. Here's a clear breakdown of what each system offers.
What Medicare Covers
As Australia's universal health insurance scheme, Medicare covers:
- GP and specialist consultations (with a referral)
- Pathology and diagnostic imaging
- Mental health services under a care plan
- Treatment as a public patient in a public hospital (including accommodation, nursing, and surgery)
- Some allied health via care plans
As a public hospital patient, Medicare covers your care fully — but you surrender the right to choose your own doctor, and you may face waiting lists for elective procedures.
What Private Health Insurance Covers
Private health insurance in Australia comes in two main types:
Hospital Cover
Hospital cover allows you to be treated as a private patient in a public or private hospital. Benefits include:
- Choice of your own doctor or specialist
- Access to private hospital rooms (depending on your policy)
- Shorter wait times for elective surgery
- Medicare covers 75% of the MBS fee for in-hospital services; your private insurer covers the remaining 25% (the "hospital excess" or "gap" may still apply)
Extras (Ancillary) Cover
Extras cover subsidises services that Medicare doesn't cover at all, such as:
- Dental (general and major)
- Optical (glasses and contact lenses)
- Physiotherapy and chiropractic care
- Ambulance (in states without a free public scheme)
- Hearing aids
- Natural therapies (depending on policy)
The Medicare Levy Surcharge (MLS)
The Medicare Levy Surcharge is an additional tax applied to higher-income earners who do not hold an appropriate level of private hospital cover. It is separate from the standard 2% Medicare Levy that all taxpayers pay.
| Income Threshold | MLS Rate |
|---|---|
| Up to base threshold (singles/families) | No MLS applies |
| Tier 1 income | 1.0% of income |
| Tier 2 income | 1.25% of income |
| Tier 3 income | 1.5% of income |
Note: Income thresholds are updated periodically. Check the ATO website for current figures.
For many higher-income earners, purchasing a basic hospital cover policy costs less than the MLS they would otherwise pay — making it financially sensible to hold private cover.
Lifetime Health Cover (LHC) Loading
The Lifetime Health Cover (LHC) loading is a government initiative designed to encourage Australians to take out private hospital cover earlier in life. Here's how it works:
- If you don't take out hospital cover by 1 July following your 31st birthday, you'll pay a 2% loading on top of your premium for every year you were without cover after age 30.
- The maximum loading is 70%, and it applies for 10 continuous years of holding hospital cover before being removed.
For example, if you first take out hospital cover at age 40, you'd pay a 20% LHC loading on your premium for 10 years.
The Private Health Insurance Rebate
To make private health insurance more affordable, the Australian Government offers a rebate on premiums. The rebate is income-tested — lower-income earners receive a higher rebate percentage. The rebate can be taken as a premium reduction (so you pay less upfront) or claimed when lodging your tax return.
Do You Need Both Medicare and Private Health Insurance?
There's no one-size-fits-all answer, but consider private health insurance if:
- Your income is above the MLS threshold and you want to avoid the surcharge
- You're approaching age 31 and want to avoid LHC loading
- You want to choose your own specialist for hospital treatment
- You want coverage for dental, optical, or other extras
- You prefer private hospital accommodation and shorter wait times
Medicare remains your foundation — it covers the bulk of everyday medical costs. Private health insurance fills the gaps and gives you more control over your care. Understanding both helps you build the right healthcare strategy for your life stage and budget.
