Public vs private hospital in Australia: what actually changes for the patient

What is the difference between a public and a private patient in Australia?

In Australia the choice that matters is not really the building. It is whether you are admitted as a public patient or a private patient, and a public hospital treats both.

A public patient in a public hospital is treated at no charge by a doctor the hospital appoints. PrivateHealth.gov.au, which the Private Health Insurance Ombudsman manages, says so in two lines: “You can be treated as a public patient in a public hospital by a doctor appointed by the hospital” and “As a public patient you will be treated at no charge.” The Department of Health, Disability and Ageing adds that Medicare then “covers all your medical expenses”. Both read on 8 October 2026.

A private patient chooses the doctor, in a public or a private hospital. Medicare pays 75% of the Medicare Benefits Schedule (MBS) fee for the doctors’ in-hospital services, and the hospital’s own charges, such as accommodation and theatre fees, fall to the patient or the insurer.

Scale, per the AIHW’s Hospitals at a glance (updated 8 September 2026): Australia’s 703 public hospitals recorded 7.7 million hospitalisations in 2024–25, 60% of the national total, against 5.1 million, or 40%, in private hospitals. In 2020–21 the split was 7.0 million and 4.9 million.

How long is the public hospital waiting list in Australia?

For planned surgery, the Australian Institute of Health and Welfare publishes the national figures each year. In 2024–25 there were 791,000 admissions from public hospital elective surgery waiting lists in Australia, 1.6% more than in 2023–24. Half of those patients were admitted within 45 days. One in ten waited 329 days or more, and 6.0% waited more than 365 days.

The trend is slowly improving, but the long tail has barely moved. The median was 48 days in 2020–21 and 46 days in 2023–24. The share waiting more than a year fell from 7.6% in 2020–21 to 6.4% in 2023–24 and 6.0% in 2024–25.

Averages hide the spread by specialty. The AIHW’s specialty page (updated 25 November 2025) reports that in 2024–25 otolaryngology, head and neck surgery had the longest median wait at 99 days, a 90th percentile of 397 days and 14% of patients waiting more than a year. Orthopaedic surgery had the second-highest share over a year, at 11%. Cardiothoracic surgery had the shortest median, 20 days. Hospital type matters too: the median was 35 days in principal referral and women’s and children’s hospitals, 49 days in public acute group A hospitals and 63 days in group B. The AIHW defines a patient as overdue at 30, 90 and 365 days for urgency categories 1, 2 and 3. Insurance waiting periods are a separate clock, covered in our waiting periods guide.

How does each state perform on public elective surgery waits?

States differ more than the national median suggests. The AIHW reports, for 2024–25, the share of public elective surgery patients admitted within the clinically recommended time for their urgency category, and how long the overdue patients waited beyond it on average. The figures below come from Table 1 of the AIHW’s waiting times overview, updated 25 November 2025 and read on 8 October 2026.

Read the two columns together. Victoria admitted the highest share on time, 84%, yet the patients it did not admit on time waited 236 days past their recommended date on average, against 60 days in New South Wales. The AIHW does not publish state-by-state median waits on that page, so none are quoted here.

What does it mean to be a private patient in a public hospital?

Being a private patient in a public hospital means you elect, at admission, to use your private health insurance in a hospital the state runs. PrivateHealth.gov.au says that with hospital cover “you have the right to choose your own doctor”, but lists choice of hospital as “No” for this option, because you are already in the public hospital. Read on 8 October 2026.

Electing to be a private patient in a public hospital is common. The AIHW’s How is care funded page, updated 18 May 2026, reports that private health insurance funded 11% of hospitalisations in Australian public hospitals in 2024–25, and that public hospitals accounted for 16% of all insurance-funded hospitalisations.

What changes for the patient, in NSW Health’s own brochure for private patients in NSW public hospitals, read on 8 October 2026:

• you may choose the specialist who treats you during the stay
• you get a single room if one is available and your cover includes single rooms
• entering through the emergency department, you are not charged an accommodation excess or co-payment
• on hospital-generated accounts, you have no out-of-pocket costs for accommodation, prostheses, pathology or radiology

The hospital, not the patient, receives the accommodation fees from the fund, and NSW Health says they “go directly to the wards and services providing care to you”. Doctors’ fees still follow the Medicare 75% rule. Restricted benefits on a low-tier policy are designed around this option, which our hospital tier comparison sets out category by category.

Why going private in a public hospital does not skip the waiting list

Believing that insurance jumps the queue is the mistake that costs people the most time. Many Australians assume that showing a membership card at a public hospital moves them up the queue. PrivateHealth.gov.au states the opposite plainly: “If you are a private patient in a public hospital, public hospital waiting lists still apply.” Checked on 8 October 2026.

The AIHW figures seem at first to say otherwise. Its waiting times by patient characteristics page, updated 21 July 2026, reports that in 2024–25 public patients on public elective surgery lists waited a median 53 days, while patients using private health insurance on those same lists waited 28 days, and other patients 24 days. In 2020–21 the figures were 51, 23 and 20 days. Insured patients made up only 5.8% of admissions from the lists; public patients made up 93%.

The two statements are reconciled by what each measures. PrivateHealth.gov.au describes the rule: the same list and the same clinical urgency categories apply. The AIHW describes an outcome across very different patients, and it does not say why insured patients waited less. Nothing on either page says a hospital may admit a patient sooner because they are insured. The AIHW reports a similar gap for cancer surgery in 2024–25: a median of 24 days for publicly funded patients and 20 days for privately insured patients (page updated 18 May 2026).

What insurance does change is the option of leaving the public list entirely. PrivateHealth.gov.au says a private patient at a private hospital “may also have more choice as to when you are admitted”. That is the route the AIHW’s 2024–25 split reflects: 67% of 2.6 million elective surgery hospitalisations happened in private hospitals.

Does Medicare cover private hospital fees, the surgeon and the anaesthetist?

Medicare pays part of the doctors’ bills for a private patient in Australia, and none of the hospital’s own charges. The Department of Health, Disability and Ageing states that “if you are a private hospital patient, Medicare covers 75% of the schedule fee for your associated medical costs”, and that Medicare “doesn’t cover hospital charges like accommodation and theatre fees”. Both read on 8 October 2026.

PrivateHealth.gov.au fills in the rest: Medicare “will pay 75 per cent of the Medicare Benefit Schedule (MBS) fee for each MBS item”, and “your health insurer will pay the additional 25 per cent”. The rule is per MBS item, not per admission, so it applies to each doctor’s item on the account, the anaesthetist’s included. Anything a doctor charges above the MBS fee is the gap, and PrivateHealth.gov.au states that “there is no cap on the amount a doctor or health care provider can charge”.

The table converts the percentages into dollars on three illustrative MBS fees, with a doctor who charges 150% of the fee. The fees are round examples, not real MBS item values. The 75% and 25% rates are the published rules.

The same specialist seen outside hospital attracts a higher Medicare share: health.gov.au says Medicare pays 85% of the schedule fee for a specialist and 100% for a GP out of hospital. The 75% rate is specific to in-hospital care as a private patient.

What is a gap payment, and what do private patients pay out of pocket?

A gap payment is the amount a private patient in Australia pays after Medicare and the insurer have paid their share. The Medical Costs Finder’s guide to costs says the same amount “also can be called an ‘out-of-pocket’, ‘patient payment’, ‘patient contribution’, or a ‘gap payment’”. On top of that sits the policy excess, which PrivateHealth.gov.au defines as “the set amount that you are obliged to pay towards the cost of hospital treatment”.

APRA’s Quarterly Private Health Insurance Statistics, June 2026 edition, released 27 August 2026, puts numbers on it. The average out-of-pocket payment on a hospital episode was A$513.24 in the June 2026 quarter, up 7.5% on the June 2025 quarter. Where a medical gap was charged, it averaged A$260.74. APRA counted 1,347,202 insured hospital episodes in the quarter, 912,102 of them in private hospitals and 174,724 in public hospitals.

Funds limit gaps through arrangements with doctors. PrivateHealth.gov.au says that at an agreement hospital “you will have either no out-of-pocket expenses or you will be provided with details of your out-of-pocket expenses”, and notes that public hospitals do not have agreements with specific insurers. Before treatment, informed financial consent applies: the Medical Costs Finder says a patient “should know what treatment you will be receiving and approximately how much it should cost”.

The Medical Costs Finder (medicalcostsfinder.health.gov.au) shows typical fees and out-of-pocket costs by service and postcode. Its disclaimer, read on 8 October 2026, says in-hospital figures come from Hospital Casemix Protocol data supplied by insurers and reflect “fees charged for treatment in private hospitals to patients with private health insurance”. Its in-hospital figures therefore say nothing about public patients, who pay nothing.

How no gap and known gap arrangements work, with a dollar example on a real MBS item, is in gap fees and out-of-pocket costs explained.

Can you be a private patient without private health insurance?

Yes. A person with Medicare can be admitted to an Australian private hospital as a self-funded patient, and the AIHW counted 6.8% of private hospitalisations as self-funded in 2024–25 (How is care funded, updated 18 May 2026). The patient pays the hospital’s charges in full. Medicare still pays 75% of the MBS fee for the doctors’ services, because health.gov.au ties that rate to being a private patient, not to holding insurance. With no insurer, nobody pays the other 25%, so the patient pays it along with any gap.

What a private hospital charges per night is the gap in the public record. As at 8 October 2026, none of the government sources read for this page, the AIHW, APRA, health.gov.au, PrivateHealth.gov.au or the Medical Costs Finder, publishes a per-night private hospital price. The Medical Costs Finder covers doctors’ fees, not accommodation. The only route to a real figure is a written quote from the hospital.

The national scale gives a sense of the money involved without being a price. The AIHW reports A$23.0 billion spent on private hospitals in 2023–24, of which private health insurers funded A$10.5 billion, or 46%. Public hospitals cost A$90.8 billion in the same year. Self-funded patients commonly ask the hospital and each doctor for written estimates before admission. Holding hospital cover also affects tax for higher earners, which our Medicare Levy Surcharge 2026–27 guide covers.

Can a public patient be treated in a private hospital?

Yes, and it happens more often than the question suggests. The AIHW’s How is care funded page, updated 18 May 2026, reports that public patients accounted for 6.0% of hospitalisations in Australian private hospitals in 2024–25. In public hospitals the same funding status covered 87% of hospitalisations.

The AIHW page does not say how those admissions were arranged, and none of the government pages read for this guide on 8 October 2026 describe a way for a patient to choose it. The public patient’s funding status is what the AIHW records, not the building. Across all Australian hospitals in 2024–25, public patients made up 54% of hospitalisations and privately insured patients 39%. A person offered treatment in a private hospital as a public patient typically asks the referring public hospital, in writing, whether any charge applies before agreeing.

Public or private emergency department: which do you go to?

In an emergency, the public hospital emergency department is the default for most Australians, because a public patient in an Australian public hospital pays nothing for care covered by Medicare. Some private hospitals run emergency departments, but health.gov.au lists “services provided through the private health system” among the things Medicare does not cover, so a private emergency department visit is not free in the way a public one is. Read on 8 October 2026.

The AIHW’s emergency department figures, updated 10 December 2025, show what the public system delivered in 2024–25. Half of patients were seen within 18 minutes, steady over the previous two years. Nine in ten were seen within 1 hour and 58 minutes. 67% were seen on time for their triage category, the same as in 2023–24 and down from 71% in 2020–21.

Being admitted from a public emergency department does not stop you using insurance. NSW Health says a private patient who enters a NSW public hospital through the emergency department is not charged an accommodation excess or co-payment, and may ask to transfer to a doctor who has treated them for the same condition before. Ambulance transport is separate again: health.gov.au lists ambulance services among the things Medicare does not cover.

Worked example: one admission, three ways

The example below is an illustration, not a quote or a procedure estimate. Mei, 52, lives in Sydney and holds hospital cover with a A$500 excess. Her specialist’s MBS fee is an illustrative A$1,000 and the specialist charges A$1,500. The anaesthetist’s MBS fee is an illustrative A$400 and the anaesthetist charges A$600. Waiting times are the 2024–25 AIHW medians for all specialties.

As a public patient in a public hospital. Doctors’ fees: A$0. Hospital charges: A$0. Excess: none, because she is not using her policy. Median wait for public patients: 53 days. She cannot choose the specialist.

As a private patient in a NSW public hospital. Medicare pays 75% of each MBS fee: A$750 plus A$300, which is A$1,050. Her insurer pays 25%: A$250 plus A$100, which is A$350. Her gaps: A$1,500 minus A$1,000 is A$500, and A$600 minus A$400 is A$200, so A$700 in total. Hospital-generated accounts in NSW carry no out-of-pocket costs for accommodation, prostheses, pathology or radiology, but her A$500 excess may apply under her policy’s terms. She is still on the public list, where insured patients’ median wait was 28 days.

As a private patient in a private agreement hospital. The doctors’ split is the same A$1,050, A$350 and A$700. Her A$500 excess applies, bringing her known costs to A$1,200. The date is set with the specialist rather than by a public list.

The gaps are the decision. If both doctors accept a no-gap arrangement with her fund, the A$700 falls to A$0 and the private hospital route costs her the A$500 excess. The exact figures belong on the written informed financial consent each doctor gives before treatment.

How do people weigh public against private?

The choice comes down to three things the sources above measure: cost, timing and who treats you. A public patient in Australia pays A$0 and accepts the hospital’s doctor and the public list. A private patient pays the gaps and the excess, which APRA puts at an average of A$513.24 per episode in the June 2026 quarter, in exchange for choosing the doctor and, in a private hospital, the date.

For many people the honest answer is that the public system is enough. The median public wait in 2024–25 was 45 days, emergency care is public by default, and electing to be private inside a public hospital buys choice of specialist but not a place higher on the list. Insurance does the most where the public tail is long: 14% of otolaryngology patients and 11% of orthopaedic patients on public lists waited more than a year in 2024–25.

There is also a tax side for higher earners. Above A$105,000 for a single in 2026–27, up from A$101,000 in 2025–26, the Medicare Levy Surcharge of 1% to 1.5% applies without hospital cover, according to the ATO, and a policy needs an excess of A$750 or less for a single to exempt you. Whether that makes cover worth holding is worked through on our do I need private health insurance guide, and the 2% levy that funds the public system is on our Medicare levy guide.
