Top Insurance Companies in Australia

Int’l desk: Australia’s insurance industry has shown remarkable resilience in a challenging environment marked by natural disasters, regulatory oversight and digital transformation. The general insurance market reached approximately AUD 68–71 billion in gross written premiums (GWP) in 2025, driven by rate hardening, claims inflation and improved underwriting profits.

Major players in the market are heavily investing in data analytics, artificial intelligence for claims processing and climate resilience modeling, while consolidation continues to reshape the landscape. A notable move in 2025 was IAG’s strategic acquisition of RACQ, which significantly boosted its market share and expanded its customer base.

Insurance Australia Group (IAG) remains Australia’s largest general insurer, commanding around 29% market share (adjusted after the RACQ acquisition). It operates several well-known brands, including NRMA Insurance, RACV (a joint venture), CGU, WFI and State Insurance. In FY25, IAG reported robust financial performance, with a net profit after tax of AUD 1.36 billion (up 51%) and GWP growth of 4.3%. The company is particularly recognised for its dominant retail and commercial presence, strong customer trust and digital transformation initiatives, although it faces challenges related to climate-driven events such as storms, floods and bushfires. Rising premiums continue to put pressure on affordability.

Suncorp Group, with a market share of approximately 25–27%, holds a significant position in the Australian insurance landscape through its brands, including AAMI, GIO, Vero and Apia. After selling its banking arm, Suncorp refocused on its insurance business, leading to strong profitability improvements in FY25. Despite natural hazard costs remaining a variable factor, Suncorp continues to lead in segments such as Queensland’s compulsory third-party (CTP) insurance. The group benefits from a simplified business model post-bank divestment and has seen solid growth in personal lines and compulsory insurance.

QBE Insurance Group, with approximately 10% of the Australian market, excels in commercial, specialty and niche areas like lenders mortgage insurance (LMI). The group also has strong international diversification, providing resilience to economic fluctuations. In FY25, QBE’s Australian Pacific division saw premium growth and improved claims ratios. The company is recognized for its specialty underwriting expertise, global reinsurance capabilities and innovation in emerging risks, such as cyber insurance.

Allianz Australia, part of the global Allianz Group, remains a significant player in the local insurance market, particularly in home, motor and business insurance. Following key acquisitions, including elements from RAA, Allianz has continued to expand its market presence. The Australian arm made substantial contributions to Allianz Group’s record performances, focusing on customer value and risk management. Allianz’s global brand backing and diversified product offerings have positioned it as a key challenger in regional markets, particularly after its acquisitions.

TAL, which leads the Australian life insurance market with a share of around 33–34%, is a major player in this segment, covering millions of Australians with strong positions in death, total and permanent disability (TPD), trauma and income protection. TAL continues to lead the life insurance space while being backed by Dai-ichi Life.

This ranking is based on 2025 data from APRA, company reports, IBISWorld, KPMG and market analyses, though it may shift with further mergers, acquisitions, or upcoming full-year results.
