Medibank Private: Australia’s Health Insurance Giant in 2025
Medibank Private continues to dominate the Australian private health insurance market, serving nearly 3.7 million members across a broad spectrum of policy options and member services that cater to diverse healthcare needs. As of 2025, Medibank, including its AHM subsidiary, commands a substantial market share of approximately 27.1%, the largest in the nation, outpacing competitors such as Bupa (24.9%), HCF (12.5%), nib (9.6%), and HBF (7.7%).
Policy Options: Hospital, Extras, and Overseas Cover
Hospital Cover
Medibank’s hospital coverage offers diverse plans from Bronze through to Gold levels, designed to fit varying budgets and medical requirements. Cover includes admission rights to public and private hospitals, surgical procedures, specialist treatments, and hospital accommodation. A standout feature is the Accident Cover Boost, available across all tiers, granting Gold-level clinical category access for unplanned accidents. This policy innovation increases protection breadth during emergencies without requiring members to upgrade their entire hospital plan.
- Market Insight: The average cost of hospital treatment in Australia has risen over 4% annually between 2021 and 2024, largely driven by specialist fees and the increasing complexity of care. Medibank’s Accident Cover Boost offsets some of this cost exposure for members.
Extras Cover
Extras cover addresses services outside hospital care such as dental, optical, physiotherapy, and chiropractic treatments. Medibank incentivizes the use of its Members’ Choice Advantage providers by offering 100% back on two dental check-ups annually (including X-rays) and 100% back on optical items, subject to annual limits.
- Usage Data: Recent internal reporting reveals that over 65% of members with extras cover utilize dental benefits yearly, reflecting strong engagement in preventive health.
Overseas Cover
Recognizing Australians’ global mobility, Medibank provides integrated overseas health insurance, covering medical emergencies abroad with 24/7 assistance. This ensures continuity of care and peace of mind when traveling.
- Trend: With international travel rebounding to 85% of pre-pandemic levels by mid-2025, demand for overseas cover options has increased by 20%, prompting Medibank to expand remote telehealth services connected with overseas emergency coverage.

Impact of 2025 Premium Increases on Customer Retention and Profitability
The private health insurance industry in Australia, including Medibank Private, experienced premium increases averaging 3.73% in 2025 — the highest rise since 2018. This adjustment reflects inflationary pressures in healthcare, including rising wages for medical staff, increased costs of advanced treatments, and greater demand for mental health services.
Customer Retention Effects
- Price Sensitivity: Premium hikes often lead to greater price sensitivity among policyholders. Some members, especially those with limited discretionary income, may seek lower-cost alternatives or reduce coverage levels, increasing industry-wide churn rates. Research suggests that a 3-5% increase in premiums typically results in a 2-4% decrease in retention rates if not offset by perceived value.
- Competitive Pressure: Rising premiums put pressure on insurers to differentiate through enhanced member services, wellness programs, and transparent communication about price increases. Medibank’s initiatives like 24/7 nurse support and mental health access aim to sustain loyalty despite higher costs.
- Prepayment and Discounts: Many insurers offer incentives for prepaid annual premiums or direct debit, which can help mitigate short-term retention challenges by locking in customers before increases take effect.
Profitability Impact
- Revenue Growth: Premium increases translate directly into higher revenue streams, supporting insurers’ ability to cover rising claims costs and invest in new services and technology. For Medibank, despite pressures from costly hospital treatments and specialists, operating profit increased by nearly 9% in FY25.
- Margin Management: While rising costs can compress margins, insurers that manage claims efficiently and maintain strong memberships, like Medibank, can preserve or grow profitability. A well-aligned premium strategy balances affordability to retain customers against the need to cover increased healthcare expenses.
- Long-Term Sustainability: Sustainable premium increases, rigorously regulated by government agencies, are critical for maintaining insurer solvency and the long-term viability of the private health insurance system, which benefits consumers through improved service and access.
Conclusion
While premium increases in 2025 challenged customer retention efforts, they were essential to offset rising healthcare costs and maintain insurer financial health. Companies like Medibank Private leveraged value-added services and loyalty programs to minimize customer loss, enabling continued profit growth and investment in member health outcomes.
Summary
Medibank Private’s 2025 financial performance confirms its leadership in the Australian private health insurance industry, driven by strong revenue and profit growth, disciplined premium management, and sustained member engagement. Its market share advantage over Bupa and other competitors remains stable due to superior retention, innovation, and diversified health service delivery.
For Medibank and its peers, the 2025 industry landscape requires navigating healthcare inflation, regulatory shifts, and digital transformation while maintaining affordability and quality for members.
