In September 2025, the Australian Competition and Consumer Commission (ACCC) raised serious concerns over Insurance Australia Group’s (IAG) proposed A$1.35 billion acquisition of RAC Insurance in Western Australia. This move could reshape Australia’s car and home insurance market, but also poses risks of reduced competition. Here’s a breakdown of what consumers and businesses should know.
The deal has sparked national debate, from WA policyholders worried about premium hikes to financial analysts questioning whether the merger could distort the insurance landscape. Below, we explore what the ACCC’s investigation means for households, businesses, and the industry’s future.
IAG–RAC Insurance Deal Under the Microscope
Background: The IAG–RAC Agreement
In early September 2025, IAG confirmed its plan to buy RAC Insurance for A$1.35 billion (approx. US$877 million). The deal involves transferring RAC’s car and home insurance portfolio in WA under IAG’s umbrella, which already controls brands like NRMA, SGIO, and CGU. According to Reuters, the acquisition could create one of the most dominant insurance positions in the state.

While IAG argues that consolidation improves efficiency and customer service, regulators are cautious about the long-term effects on competition.
- Transaction value: A$1.35 billion
- Brands involved: NRMA, SGIO, CGU, plus RAC Insurance WA
- Primary concern: market concentration
Why the ACCC Is Concerned
The ACCC has highlighted that IAG already holds a significant share of the WA insurance market. By absorbing RAC Insurance, IAG could reduce consumer choice and potentially raise premiums. The regulator’s preliminary review notes the risk of “substantial lessening of competition.”
WA households are particularly vulnerable, as RAC Insurance currently provides a local alternative with strong brand trust. Removing that option could weaken competitive pressure on pricing and coverage.
Case example: Perth families with long-term RAC home insurance policies fear fewer competitive discounts in the future if IAG dominates the market.
- Market power consolidation
- Higher premiums possible
- Reduced consumer choice
💡 What Does This Mean for Policyholders?
For everyday Australians, the biggest worry is cost. If IAG proceeds, policyholders may see gradual increases in premiums or fewer promotional offers. This could add hundreds of dollars annually to household budgets, particularly for families with both car and home policies bundled together.
Consumer groups in WA have already begun lobbying for stricter conditions, such as price monitoring and transparent reporting. ACCC’s final decision, expected in late 2025, will determine how much protection is offered.
Personal story: A WA teacher paying A$2,100 annually for combined home and car cover fears a 10% hike post-merger—adding A$210 per year to living costs.
- Premium affordability at risk
- Bundled cover discounts under pressure
- Trust in RAC brand may diminish
Impact on Small Businesses
It’s not just households. Small businesses relying on RAC Insurance for commercial vehicle or property cover could face similar challenges. Reduced competition may shrink tailored product offerings, making it harder for SMEs to find affordable, flexible insurance solutions.
WA’s Chamber of Commerce has already flagged concerns that local small enterprises could face steeper operating costs. Higher premiums on delivery vehicles, for instance, could trickle down to consumer prices.

💡 Could This Deal Reshape the National Insurance Market?
Yes. Although centred in WA, the merger could have ripple effects nationwide. If approved, IAG would cement itself as the most dominant insurer in Australia, potentially setting benchmarks for pricing and service levels. Other insurers may respond with competitive strategies, but smaller providers could struggle.
For investors, this is a double-edged sword: while consolidation could drive efficiency and shareholder returns, it also raises reputational risks if premiums spike.
- National market concentration risk
- Possible domino effect in other states
- Investor interest vs. consumer costs
Regulatory Options and Possible Outcomes
The ACCC may either block the deal, approve it unconditionally, or allow it with enforceable undertakings. Likely measures could include caps on premium increases, mandatory policy transparency, or divestment of certain assets to preserve competition.
Similar cases in the past show that mergers of this scale often proceed only with strict oversight. If blocked, RAC could continue to operate independently, preserving market balance.
Consumers and businesses alike are advised to follow the ACCC consultation process closely. Public submissions remain open until late October 2025.

Key Takeaways for Consumers
This deal could redefine Australia’s insurance landscape, especially in WA. While efficiency gains are possible, risks of higher costs and fewer choices loom large. Policyholders should review existing contracts, explore alternative insurers, and stay informed about ACCC’s decision.
Practical tip: Compare at least three different providers before renewal. Even in a concentrated market, competition still exists, and switching could save hundreds annually.
