(Re)in Summary
- IAG and RAC WA have asked the Australian Competition Tribunal to overturn the ACCC’s decision blocking IAG’s A$1.35 billion (US$940m) acquisition of RAC Insurance.
- The ACCC twice opposed the deal, estimating a combined IAG-RACI would hold 55–65% of WA’s motor market and 50–60% of home and contents, with rivals unable to provide enough competitive constraint.
- The parties argue the regulator wrongly assessed the share purchase in isolation rather than as part of the wider strategic alliance, under which RAC keeps distribution while IAG takes on underwriting, pricing and claims.
- IAG is also lodging a public benefit application with the ACCC, which has 50 business days to decide whether the deal’s broader benefits outweigh any loss of competition.
Insurance Australia Group (IAG) and the Royal Automobile Club of Western Australia (RAC) have asked the Australian Competition Tribunal to overturn the competition regulator’s decision to block IAG’s acquisition of RAC Insurance (RACI).
The Tribunal is the appeal body for Australian Competition and Consumer Commission (ACCC) merger decisions. In separate applications lodged on 1 and 5 October, IAG and RACWA Holdings argue the ACCC erred in finding the deal would substantially lessen competition. Both want the ACCC’s 22 September final (Phase 2) determination set aside and replaced with clearance for the deal to proceed.
Apart from the tribunal challenge, IAG is also pursuing another route: a public benefit application, asking the ACCC to approve the deal on the basis that its broader benefits outweigh any loss of competition. The regulator has 50 business days to decide.
Announced in May 2025, the transaction has two parts: A$400m (US$278m) for 100% of RACI’s shares, and an A$950m upfront payment for a 20-year exclusive distribution and brand licence agreement. Under that arrangement, RAC would continue to distribute RAC-branded home, motor and speciality products to its members, while IAG would take on underwriting, pricing and claims.
IAG has said the portfolio would add roughly A$1.5bn in gross written premium (GWP) and deliver about A$100m in pre-tax annual synergies, including reinsurance savings.
The ACCC first opposed the deal in December 2025 under the old informal clearance process. It estimated a combined IAG-RACI would hold 55–65% of Western Australia’s motor market and 50–60% of home and contents, and found that rivals Suncorp, Allianz, QBE, Auto & General, Youi and Hollard would not provide enough competitive constraint.
IAG re-notified in March 2026 under the new mandatory regime, which requires deals above certain thresholds to be formally notified and cleared before completion. The ACCC reached the same conclusion.
The challenge is the first serious test of how Australia’s new merger rules, in force since 1 January, will apply to insurers.
IAG and RAC’s case is as much about how the ACCC assessed the deal as about the competition facts. They argue the regulator should have looked at the acquisition as part of the wider “strategic alliance” between the two companies, rather than the share purchase in isolation, which they say s 51ABZH(3) of the Competition and Consumer Act allows.
That alliance includes the distribution agreement, brand licence, transitional services and a buyback deed giving RAC an option to reacquire the portfolios. RACWA Holdings also stresses that IAG is not acquiring RAC’s distribution business. It has asked the Tribunal to hear both applications together and to charge only one filing fee.
