Lesson 11 · How does the healthcare system work?
Health expenditure II: Medicare, private cover and Commonwealth-funded programs
Medicare is the single most consequential health policy in Australian history, and most students can describe what it pays for without being able to say what it is for. The distinction matters: understanding the purpose explains the design, the gaps, and every argument about private health insurance that follows from them.
Two people need the same operation. One has private health insurance; one does not. Both are treated, and both recover.
Write down three things that were probably different about their experience. Then say which of those three differences you think matters for their health, and which matters only for their convenience.
- Explain what Medicare is for, how it is funded, and what it does and does not cover.
- Explain how pharmaceutical subsidy works alongside it and why it matters for chronic conditions.
- Explain the role of private health insurance, and the arguments for and against public support for it.
- Describe related Commonwealth-funded programs, including the National Disability Insurance Scheme and My Aged Care.
- Assess what these arrangements together mean for access and equity.
- Medicare — Australia's universal health insurance scheme, funded from general taxation and a levy, providing free public hospital treatment and subsidised medical services.
- Universal — available to the whole population on the basis of residence and need, not of contribution or employment.
- Schedule fee — the fee the scheme uses to calculate its rebate for a service; the practitioner is free to charge more.
- Bulk billing — the practitioner accepts the rebate as full payment, so the patient pays nothing at the point of care.
- Gap — the difference between what is charged and what is rebated, paid by the patient.
- Safety net — an arrangement that raises the level of subsidy once a person's out-of-pocket costs in a year pass a threshold.
- Pharmaceutical subsidy — government subsidy of listed medicines so that patients pay a capped contribution rather than the full price.
- Private health insurance — voluntary cover for private hospital treatment and for services outside Medicare, such as dental and optical.
- Community rating — the rule that a private insurer must charge the same premium regardless of a person's health status or claims history.
The purpose first. Medicare exists so that a person's ability to obtain necessary medical care does not depend on their ability to pay for it, and so that illness does not cause financial ruin. Every design feature follows from those two aims, and every criticism of it is a claim that one of them is not being met.
How it is funded. From general taxation, supplemented by a levy on taxable income, with a higher levy for higher-income earners who do not hold private hospital cover. It is not a fund people pay into and draw down; it is current taxation paying for current care.
What it provides.
- Free treatment as a public patient in a public hospital, with the doctor allocated by the hospital rather than chosen by the patient.
- Rebates for medical services out of hospital: general practice, specialists, pathology and imaging. The rebate is calculated from a schedule fee, and the practitioner may charge more than that.
- Subsidised medicines through the separate pharmaceutical arrangements, with a lower contribution for concession card holders and a safety net once a household's annual contributions pass a threshold.
- Safety nets that raise the rebate once out-of-pocket costs for the year exceed a threshold.
What it does not cover. Most dental care for adults; most physiotherapy, psychology and other allied health beyond limited arrangements; optical; ambulance in most states; and private hospital treatment. That list is not random — it is where the out-of-pocket costs from the previous lesson are concentrated, and it is where the access gradient shows.
Medicare is universal in coverage of the population and partial in coverage of services. Nearly every argument about Australian healthcare access is about that second half.
Quick check: Which best states the purpose of Medicare?
This is the mechanism worth understanding properly, because it is the clearest example in Australian health policy of a design working exactly as written and producing an outcome nobody chose.
- The rebate is calculated from a schedule fee set by government.
- Practitioners set their own fees. If they charge the schedule fee and bill the scheme directly, the patient pays nothing — bulk billing.
- If they charge more, the patient pays the gap.
- The schedule fee is adjusted by government decision. When it rises more slowly than the cost of running a practice, the gap between what a practice must charge and what the scheme rebates widens, year after year, without any single decision to introduce a co-payment.
- Bulk-billing rates then fall, and they fall unevenly — typically last in areas where patients can least afford a gap, until the practice can no longer sustain it.
A co-payment can be introduced without ever being announced, simply by holding a rebate still while costs rise. This is the single most useful policy mechanism to understand in this dot point, because it explains how universal coverage erodes without anyone legislating an erosion.
Two consequences to carry into an answer. First, the effect is concentrated: for a person on a low income with a chronic condition needing frequent visits, a modest gap multiplied by many visits is a real barrier, and safety nets help only after the threshold is reached — which requires paying up to it first. Second, deterred primary care presents later and more expensively somewhere else, which is the chain from Lesson 10 running again.
True or false: A co-payment can effectively be introduced without any announcement, by holding the rebate steady while the cost of providing the service rises.
What it does. It covers treatment as a private patient — in a private hospital, or as a private patient in a public one — which brings choice of doctor, choice of timing and a private room. Ancillary or “extras” cover pays toward services Medicare largely excludes: dental, optical, physiotherapy and similar.
How government supports it. Through a rebate reducing premiums, through a levy surcharge on higher-income earners who do not hold hospital cover, and through an arrangement that raises premiums for people who take out cover later in life. It is voluntary insurance with substantial public support and substantial public regulation, including community rating — insurers must charge the same premium regardless of health status, which is what stops them from simply refusing the sick.
The argument for public support. It shifts some demand out of public hospitals, freeing public capacity; it draws additional private money into health; and it lets people who want choice exercise it without leaving the public system to those who cannot pay.
The argument against. Public subsidy of private insurance is public money spent on people who are, on average, better off, and the same money spent directly on public hospitals or on primary care would buy more health for more people. Private cover also concentrates in higher-income groups, so support for it is regressive. And a two-tier arrangement can create different waiting times for the same condition, which sits awkwardly beside the principle that care should follow need.
The honest position for an exam answer: both arguments are about the same fact. Private cover does move demand and money, and it does so in a way that follows income rather than need. Whether that is acceptable is a value judgement about what the health system is for, and saying so explicitly is stronger than pretending the evidence settles it.
Fill the gaps. When a practitioner accepts the rebate as full payment so the patient pays nothing, this is called bulk . The rule requiring a private insurer to charge the same premium regardless of a person's health status is called community .
Two large schemes sit beside Medicare, funded federally, and both illustrate the same design idea: funding that follows the person rather than the service.
- The National Disability Insurance Scheme. Funds reasonable and necessary supports for people with permanent and significant disability, through an individual plan built around the person's own goals. It is insurance-shaped: the whole population contributes, and support is available to those who need it. It is not a health scheme — it funds supports for daily life, participation and independence rather than medical treatment — and the boundary between it and the health system is one of the seams from Lesson 9. It is also the clearest large-scale application of person-centred design in Australian policy, because the plan starts from the person's goals.
- My Aged Care. The entry point to federally funded aged care: assessment, then home support, home care packages or residential care. Its design intent is to support ageing in place for as long as possible, which is both what most people prefer and generally less costly than residential care. Its recurring problems are assessment and waiting times, workforce, and navigation — the system is hard to enter at exactly the moment a family is least equipped to work out how.
Both schemes have the same two structural characteristics, and naming them is worth more than describing the schemes:
- Funding attached to a person, not to a service. This is what makes individualised, goal-based support possible, and it also transfers the work of choosing and coordinating providers onto the person or their family — which advantages those with the capacity to navigate.
- A boundary problem with health. Someone can need health care, disability support and aged care at once, funded by different programs with different rules, and the seam between them is where delays and gaps appear — most visibly as people waiting in hospital for a funded place elsewhere.
Two truths and a lie. One of these statements is false. Find it.
Pull the whole picture together. There are three genuine achievements and three genuine problems, and a complete answer has both.
What the arrangements achieve
- Cost is not an absolute barrier to core care. Nobody in Australia is refused emergency or public hospital treatment for inability to pay, which is not true everywhere.
- Medicines are affordable. Subsidy plus safety nets makes lifelong treatment for chronic conditions possible for most people; without it, chronic disease management would fail at the pharmacy counter.
- Risk is pooled across the whole population. Funding from general taxation means the healthy and the wealthy contribute to the care of the sick and the poor, which is the definition of a universal scheme and the reason it produces better equity than voluntary insurance alone.
Where they fall short
- The uncovered services are the ones with the sharpest gradient. Dental care especially: outside universal coverage, most often delayed for cost, and its consequences arrive later in hospitals.
- Gaps erode universality silently. A rebate that does not keep pace introduces a co-payment nobody announced, and it bites hardest on frequent users with low incomes.
- Public support for private cover follows income rather than need. Whether that is justified is a value judgement, but its distributional effect is not in dispute.
Two general observations that make an evaluation feel authoritative:
- The design of the coverage boundary matters more than the size of the budget. Which services sit inside universal coverage determines who is protected, and it does so more directly than the total spent.
- Universality is not self-maintaining. It erodes through indexation, through eligibility rules and through gaps, none of which requires a decision to end it. Defending it is a continuing activity, not a past achievement.
Activities · follow the money to the patient
For each, say who funds it and what the patient is likely to pay, and name the access consequence.
A public patient has surgery in a public hospital.
A person with a chronic condition sees a specialist who charges above the schedule fee, four times a year.
An adult needs three fillings and a tooth extraction.
An older person is medically ready to leave hospital but needs a home care package that has not yet been assigned.
Match each arrangement to what it is designed to do.
- Safety net
- Community rating
- Pharmaceutical subsidy
- Individualised funding
- Raise the level of subsidy once a person's yearly out-of-pocket costs pass a threshold
- Stop insurers charging more, or refusing cover, because of a person's health status
- Cap what a patient pays for a listed medicine, so lifelong treatment stays affordable
- Attach funding to the person and their goals rather than to a service
A government has decided to bring one currently excluded service inside universal coverage. Choose adult dental care or psychological therapy.
Argue for your choice using: the access gate it would fix, who would benefit most and why, the opportunity cost of the money, and one likely unintended consequence. Then say how you would know, five years later, whether it had worked — naming a measure that would move and a measure that would not.
Lock it in. In one sentence, explain why Medicare can be described as universal and still leave some Australians facing a cost barrier to care.
Analyse how Medicare, private health insurance and Commonwealth-funded programs interact to fund healthcare in Australia.
Analyse asks for the parts and their relationships. Describing each scheme separately is the trap here — the stem's word is interact.
Plan: identify the components, state what links them, relate them across the situation, then draw the implication.
Four funding components operate together: Medicare, funded from general taxation and the Medicare levy, covering medical services and public hospital treatment; the Pharmaceutical Benefits Scheme, capping medicine costs; private health insurance, funded by member premiums and supported by government incentives; and targeted Commonwealth programs including the National Disability Insurance Scheme and My Aged Care.
The components are linked by a single constraint: total demand for care is finite in the short run and the public and private systems draw on the same workforce and much of the same infrastructure. Policy therefore uses private insurance to shift demand out of the public system, through the Medicare Levy Surcharge, the private health insurance rebate and Lifetime Health Cover loading.
That relationship runs in both directions. Where private insurance takes pressure off public waiting lists it frees public capacity, but because both systems recruit from the same pool of specialists and nurses, growth in private activity can also draw workforce away from public hospitals, so the intended relief is partly offset.
The defining case is the person who is insured but still faces a gap payment. They have paid a premium, attracted a rebate, and yet may still decline specialist care on cost grounds — which shows that the components are layered rather than complementary, and that a person's cost of care depends on which layer their particular need happens to fall into.

Evaluate the effectiveness of the National Disability Insurance Scheme in improving health outcomes for Australians with disability.
Evaluate requires a judgement against criteria. The stem restricts the judgement to health outcomes, so keep the criteria pointed at health rather than at the scheme's administration in general.
Plan: criteria, the case for, the case against, a verdict that commits, then a qualification.
The scheme will be judged against whether it improves access to the supports that maintain health and function, whether it reaches those eligible equitably, and whether the support it provides is stable enough to produce a long-term health benefit.
Against the first criterion the scheme has real force. Individualised, portable funding replaced block-funded services that rationed by queue, so participants can purchase therapy, equipment and personal care matched to their own goals rather than to a provider's program. Early intervention funding for children can alter developmental trajectories, and the shift toward participant choice supports independence and social participation, both of which are themselves determinants of health.
Against equity and stability the performance is weaker. Access depends on navigating a complex application and planning process, so participants with lower health literacy, limited English, no advocate, or living remotely obtain less than their entitlement — reproducing the inequities the scheme was meant to remove. Thin markets in rural and remote areas mean funding exists where providers do not. And plan reviews and funding variability disrupt continuity of therapy, which is precisely what long-term functional gains depend on.
On balance the scheme has been more effective at improving the quality and relevance of support for those who successfully access it than at distributing that support equitably. Its central mechanism — individualised funding — works, but that same mechanism transfers the burden of navigation onto the participant, so it advantages those already best resourced to advocate for themselves.

Its effectiveness should therefore be judged on the gap between entitlement and utilisation rather than on plan budgets alone.
Return to card 01, the two patients. You separated the differences that mattered for health from those that mattered for convenience. Now check: did any of your “convenience” differences turn out to be timing? Waiting longer for the same operation is a convenience difference until the wait changes the outcome, and where that line falls is exactly the argument about a two-tier system.

Activity 1 model answers: 1 → Funded jointly by federal and state government; the public patient pays nothing for the admission; access is protected, though timing depends on the waiting list rather than on the patient. 2 → Federally rebated with a gap paid by the patient at each visit; four visits multiply a modest gap into a real barrier, and safety nets only assist after the threshold is reached, which requires paying up to it first. 3 → Largely unfunded for adults outside limited public dental arrangements, so the patient pays most or all of it; this is the service most often delayed for cost, with a strong socioeconomic gradient and consequences that arrive later as preventable admissions. 4 → The hospital bed is state-funded and the home care package is federally funded; the patient pays nothing but loses time and function, and this seam between two funders is where cost-shifting incentives and discharge delays appear.
SA 1 (4 marks): Covers: free treatment as a public patient in a public hospital, rebates for medical services in the community, and subsidised medicines with safety nets [2]. Does not cover: most adult dental, most allied health and psychology, optical, ambulance in most states, and private hospital treatment [1]. Consequence explained: those excluded services are where out-of-pocket cost concentrates, so cost operates as an access barrier there and produces a socioeconomic gradient in outcomes for exactly those services, most clearly in dental care [1].
SA 2 (5 marks): The rebate is calculated from a schedule fee set by government, while practitioners set their own fees [1]. If the schedule fee is indexed more slowly than the cost of providing the service, the difference between fee and rebate widens over time [1]. Practices that had been bulk billing can no longer sustain it and begin charging a gap [1]. Patients therefore face a co-payment that was never announced or legislated [1]. The effect is concentrated on frequent users with low incomes, and deterred primary care presents later and more expensively elsewhere, so the erosion is both an equity and a cost problem [1].
SA 3 (6 marks): Medicare described accurately by purpose and by mechanism: universal in population coverage, funded from taxation and a levy, providing public hospital treatment, medical rebates and subsidised medicines [1]. Private health insurance described with its public support and its regulation, including the requirement to charge the same premium regardless of health status [1]. Commonwealth programs described, with the shared feature that funding follows the person, and the boundary problem this creates with the health system [1]. Evaluation of achievements: cost is not an absolute barrier to core care, medicines are affordable, and risk is pooled across the population [1]. Evaluation of shortfalls: the uncovered services carry the sharpest gradient, gaps erode universality without any decision to erode it, and support for private cover follows income rather than need [1]. Judgement: the boundary of coverage matters more than the size of the budget, and universality is not self-maintaining, so the arrangements deliver strong equity in what they cover and reproduce the social gradient in what they do not [1].
The single sentence to take from this lesson: coverage is a boundary, and where the boundary sits decides who is protected. Everything else — bulk billing, gaps, safety nets, private cover, the two Commonwealth schemes — is a detail of how that boundary is drawn and how it moves.
Check your Practice answers for one thing: did you explain the gap mechanism, or just state that gaps exist? The mechanism is the mark.
