$1.7 Billion Profit, Then a Medibank Premium Increase 2025?

▶

In 2023–24, Medibank, Bupa and NIB together made about $1.7 billion in pre‑tax profit, yet the federal Health Minister still approved above‑average premium hikes of up to 5.79% for them from 1 April 2025, meaning customers pay more into already record‑profitable funds.

The number that matters

3.99% — average Medibank premium hike in 2025, despite record profits

For the 2025 premium round, Medibank received approval for a 3.99% average premium increase, above the 3.73% industry average that the Minister said he set while explicitly acknowledging insurers’ “years of record profits.”

• What it measures: The government‑approved percentage rise in Medibank’s health insurance premiums from 1 April 2025.
• Source & year: Department of Health & Aged Care decision reported by The Australia Institute using 2023–24 APRA profit data and the 2025 premium decision.

How it quietly costs you

Mechanism: Government‑approved annual premium resets that do not constrain profit margins

1. Annual review process allows increases even when profits are strong

• Health funds must get every premium change approved by the Federal Health Minister after an annual review.
• The Minister approved an average 3.73% industry increase from 1 April 2025, but allowed Medibank, Bupa and NIB above‑average rises of 3.99%, 5.10% and 5.79% respectively.
• These approvals came despite the Minister publicly acknowledging that the big insurers had logged “years of record profits.”

2. Record profitability does not trigger lower or rejected increases

• APRA data collated by The Australia Institute shows Medibank, Bupa and NIB together made $1.7 billion pre‑tax profit in 2023–24, while the remaining 27 insurers made only $545 million combined.
• The big three therefore captured about 59% of total pre‑tax profit in a market where the top five funds take 79% of all premium income.
• Yet those same big three were each granted higher‑than‑average premium increases for 2025.

3. Direct household impact: dollars per fortnight

• Medibank’s own 2024 announcement shows how percentage hikes translate into cash:
• A 3.31% increase (their 2024 average rise) equals about $2.30 per fortnight extra for a single on a Bronze hospital & extras policy, and $11.80 per fortnight for a family on Silver hospital & extras.
• A 3.99% increase in 2025 is larger than that 3.31% example:
• If a family’s Silver policy cost $11.80 per fortnight more under 3.31%, a 3.99% rise would add roughly 20% more again, or about $14 per fortnight, purely from the 2025 change (approximation based on proportional scaling).
• Over a year, that is roughly $364 extra for that family compared with pre‑rise premiums (26 fortnights × about $14).

4. Old vs “better” comparison

• The Department of Health indicates the long‑term industry average premium increase is around 3.8% per year over the last decade.
• Medibank emphasises that its 2024 hike of 3.31% was below that 10‑year industry average.
• But in 2025, Medibank’s 3.99% rise is above the 3.73% industry average set by the Minister and above the 10‑year average, despite its share of the $1.7 billion pre‑tax profit pool.

Bottom line: The regulatory design focuses on whether increases can be justified by rising healthcare costs, not on capping margins or scaling back increases when profits are very high, so Medibank can raise premiums while still posting record profits.

The second, compounding trap

Mechanism: A concentrated, for‑profit, community‑rated market keeps customers “stuck” and lets the largest funds scale profits off compulsory‑style demand

1. High market concentration gives big funds pricing power

• Australia’s private health insurance industry is highly concentrated, with the top five funds (Medibank, Bupa, NIB, HCF, HBF) taking 79% of all premium income.
• The three for‑profit giants — Medibank, Bupa and NIB — alone earn 59% of all pre‑tax profits.
• In a concentrated market with limited effective switching, large for‑profit funds can maintain higher margins without losing many customers, especially when premium structures are complex and hard to compare.

2. Community rating + government incentives keep money flowing in

• Under community rating, funds cannot charge you more based on your health status or claims history and cannot refuse to sell you a policy based on health risk.
• Instead, prices are largely driven by product design and age‑related loadings (Lifetime Health Cover), not how healthy you are personally.
• Government settings such as the Medicare Levy Surcharge and Lifetime Health Cover loading effectively push higher‑income and older Australians into holding hospital cover to avoid extra tax or surcharges, even when premiums rise.

3. Rising premiums on a “must‑have” product compound over time

• Industry‑wide, 2025’s 3.73% average premium rise was described as driven by rising treatment costs, wages, hospital costs and an ageing population.
• Some reports show recent rounds have been among the fastest premium rises in almost a decade, with average increases of around 4.41% in some years.
• With premium inflation consistently around 3–4% per year over a decade, a household paying $4,000 per year today could be paying about:
• Year 1: $4,000
• Year 10 at 3.5% p.a.: roughly ( 4,000 × (1.035)^{10} ≈ <mark class=“fig”>$5,640 ) — about $1,640 more per year after ten years, driven largely by regulated, annually‑approved increases.

4. Long‑run cost of inaction (not switching or downgrading)

• Because community rating prevents price discrimination by health status, loyal, low‑claiming members effectively subsidise higher claimers on the same product.
• If that $4,000‑per‑year family never switches from a large for‑profit fund charging above‑average premiums, and premiums grow at 3.5% per year for 30 years, the family will pay roughly:
• Total premiums ≈ ( 4,000 × \frac{(1.035)^{30} - 1}{0.035} ≈ <mark class=“fig”>$203,000 ) over three decades.
• If a competing fund or lower‑tier product could provide equivalent hospital cover for 10% less on average, failing to switch or downgrade could cost that family around $20,000 over 30 years (10% of the cumulative outlay), just from staying put in a concentrated, for‑profit segment.

Bottom line: Concentration, community rating, and tax incentives create a “captive” customer base who pay ever‑rising regulated premiums, allowing large for‑profit funds like Medibank to grow profits and premium revenue at the same time.

What this looks like in practice

Persona

• Name: Sarah
• Age: 39
• Job: HR manager at a mid‑size firm in Sydney
• Income: $115,000 per year (taxable)
• Fund/account type: Medibank family Silver hospital + extras cover
• Current annual premium (pre‑2025 hike): about $4,500 per year (≈ $173 per fortnight) — consistent with Medibank’s example where a Silver family policy rises $11.80 per fortnight after a 3.31% increase, implying a base of roughly $357 per fortnight for some policies; using a conservative lower figure for a standard family Silver product.
• Years to retirement: 28–30

Discovery 1 — Her premium is rising faster than wages and CPI

• Medibank’s 2024 approved increase was 3.31%, “below inflation and wage growth,” according to the fund.
• But in 2025, Medibank’s increase of 3.99% is above both the 3.73% industry average and the 10‑year industry premium average of 3.8%.
• If Sarah’s $4,500 premium rises by 3.99% in 2025, it will jump by about $180 to $4,680 in a single year.
• Over 10 years of similar increases (3.8–4% per year), that $4,500 becomes roughly $6,300, adding about $1,800 per year to her household’s cost of living.

Discovery 2 — Her fund is one of the most profitable in an already concentrated market

• Sarah learns that Medibank, Bupa, and NIB together made $1.7 billion in pre‑tax profit in 2023–24, while all 27 other funds combined made only $545 million.
• These three for‑profit funds captured 59% of pre‑tax profits in a market where the top five funds take 79% of all premium income.
• She realises she is paying rising premiums into an insurer that sits inside the most profitable and dominant cluster in the market, even as it argues increases are needed to cover rising costs.

Discovery 3 — Switching or downgrading could be worth tens of thousands over her career

• If Sarah keeps paying around $4,500, rising at about 3.5% a year for 30 years, she will pay roughly $230,000 in premiums over her working life (slightly higher than the earlier $203k example, reflecting her higher starting premium).
• If she switched to a comparable policy at a strong not‑for‑profit or lower‑priced competitor charging just 10% less on average, she could save about $23,000 over 30 years.
• Compared with “doing nothing” and staying in a for‑profit giant that won an above‑average premium increase in 2025, Sarah’s lifetime saving from one switching decision now is the equivalent of several years of premiums in retirement.

The full cost of doing nothing

For someone like Sarah, the combined impact of:

• (Problem 1) Regulated above‑average premium increases granted despite record profits, and
• (Problem 2) Staying with a dominant for‑profit fund in a concentrated market instead of a lower‑priced alternative

can conservatively cost around $20,000–$25,000 over her remaining working life.

Modelling basis (assumptions):

• Starting premium: $4,500 per year for family cover.
• Premium growth: 3.5–3.9% per year for 30 years, consistent with the 10‑year industry average (~3.8%) and recent approvals around 3.31–4.41%.
• Competitor “good” option: a comparable not‑for‑profit or lower‑priced fund with premiums 10% lower on average over time.
• All figures in real dollars without discounting; savings are the cumulative 10% difference on total premiums over 30 years, approximating $23,000 in avoided payments.

What to do about it

1. Compare your fund’s increase and shop for lower premiums

1. Action: Check your premium increase and compare with other funds.
2. Tool/portal:

• Medibank website Premium Review page for your exact increase.
• Government YourSuper or private health comparison sites (where available) to benchmark premiums.

3. Steps:
4. Log into your Medibank online account or read your premium‑change email/letter to see your percentage increase and new dollar premium.
5. Go to a reputable health insurance comparison tool and enter your age, location and cover type (family, single, Silver/Bronze etc.).
6. List alternative policies with similar hospital cover and note at least two options that are 5–15% cheaper than your current premium.
7. What “good” looks like:

• Your annual premium is at least 5–10% below Medibank’s quote for equivalent cover, and your fund’s approved increase is at or below the industry average (e.g. ≤3.73% in 2025).

2. Audit your cover level vs what you actually use

1. Action: Strip out unnecessary extras or downgrade tiers if over‑insured.
2. Tool/portal:

• Medibank policy schedule in your online account or annual statement.

3. Steps:
4. Download your current policy summary and list each included service (e.g. obstetrics, joint replacement, high‑end extras).
5. Check the last 2–3 years of claims (visible in your Medibank account) to see which services you actually used.
6. Get quotes for a lower tier (e.g. from Silver to Bronze, or cutting extras) that still covers the services you have used or realistically expect to use.
7. What “good” looks like:

• You are not paying for high‑cost categories you do not need in the next 5–10 years (e.g. pregnancy when your family is complete). Savings of $500–$1,000 per year are realistic for many households when dropping unneeded extras and tiers.

3. Use community rating to your advantage and switch without penalty

1. Action: Switch funds if another insurer offers better value; you keep your rights under community rating.
2. Tool/portal:

• New fund’s online sign‑up plus your existing Medibank policy details.

3. Steps:
4. Choose a new fund and policy with equivalent or better hospital cover at a lower premium (aim for at least 10% cheaper).
5. Apply online and tick the box for the new fund to cancel your old policy; provide your Medibank membership number.
6. Confirm continuity of cover and waiting period recognition in writing from the new fund before cancelling any direct debits.
7. What “good” looks like:

• Your new policy costs 10% or more less than your old one, while maintaining the core hospital cover you need. You have continuous hospital cover with no new waiting periods for existing conditions, thanks to community rating and portability rules.

A myth worth clearing up

Myth: “If I switch health funds, they can re‑price me based on my medical history, and I’ll face new waiting periods.”

Fact: Under Australia’s community rating rules, a health fund cannot charge you more based on your health or claims history and cannot refuse to sell you a policy because of your health risk. When you move between equivalent hospital policies, your new fund must generally recognise your existing waiting periods, so you are not “punished” for switching. This means switching is a viable way to escape higher‑priced, highly profitable funds like Medibank.
