For now, giant insurer IAG’s bid to purchase The Royal Automobile Club of Western Australia’s (RAC WA’s) insurance business is blocked. But the story is far from over.
The ACCC’s decision to oppose the $1.35 billion acquisition has drawn a line under one of the most contentious proposed deals in Australia’s personal motor insurance market. It has also set up an important test of the new merger regime that comes into play on January 1 and how far consolidation in state-based motor books can go before regulators say “enough”.
IAG has already announced its intention to lodge another application with the ACCC in the hope that, under the new rules, the regulator might see things differently. In the meantime, some brokers in WA see the block as a win for competition – and for their clients.
“This is great news for us Western Australians,” said Alex Cox (main picture), Bellrock’s practice leader in Perth. The WA broker said he fully supports a free-market economy but competition needs to be fair.
“I am all for a free-market economy but this move would have tipped the scales to the detriment of 3 million Westerns Australians,” said Cox.
He applauded the regulator’s decision as fulfilling its role to protect the business environment and consumers.
“The role of the ACCC is to protect competition, improve consumer welfare and stop conduct that is anti-competitive or harmful to consumers – and they have done just that,” said Cox.
For brokers, the blocked deal halts a rapid concentration of personal motor insurance under a handful of east-coast based giants. Had the acquisition proceeded, IAG’s share of WA’s private motor insurance market would have risen, said the ACCC, to between 55 and 65 per cent. This would have significantly narrowed the range of genuine pricing and product alternatives, likely also impacting those brokers could present to clients. That is a particular concern in a state where repair costs are already elevated by geography and supply-chain constraints, and where fewer major players can quickly translate into upward pressure on premiums and tougher negotiations at renewal.
In the context of a year that’s already seen two major acquisitions approved – IAG’s takeover of RACQ Insurance in Queensland and Allianz’s purchase of RAA Insurance in South Australia – the MTAA said the block on IAG’s WA move was “a critical step in protecting competition, consumers and the viability of Australia’s automotive repair industry.”
For industry observers, the key question is why the ACCC drew the line in Western Australia after waving through similar club-insurer deals in Queensland and South Australia.
The answer appears to lie in market structure and concentration. In WA, the combination of IAG and RAC’s insurance arm would have left one group with control of a majority of private motor, underpinned by a powerful motoring club brand and deep links into the repair ecosystem. That raised red flags not only about pricing and product choice, but also about bargaining power over repairers and the long-term viability of independent shops – issues the MTAA has campaigned on for years.

By contrast, the RACQ and RAA transactions were struck in markets where the club-owned insurers were smaller, the competitive field more fragmented, and the resulting combined shares stayed further away from the sort of 60–65% watermark that alarms competition lawyers.
In other words, the WA decision looks less like an about-face on insurer consolidation and more like the ACCC signalling that there is a hard upper bound on how concentrated a state’s motor market can become – particularly where there is vertical integration across distribution and repairs.
For brokers, the immediate impact is that one more serious retail motor market remains in play. Placement strategies and renewal negotiations can still leverage a wider bench of carriers rather than dealing with an even more dominant IAG–RAC combination.
Over the medium term, the block may embolden smaller and niche players – including challengers in usage-based, EV, and fleet products – to invest in WA, confident that regulators are prepared to step in before the market tilts too far towards a single dominant insurer. That could support more innovative wordings, delegated authorities and mid-market schemes backed by more than one or two majors.
On the flip side, some in the industry will argue that scale brings its own efficiencies: better claims technology, larger catastrophe pools and potentially sharper pricing in benign loss years. The ACCC has effectively judged that, in WA motor, the downside risk to competition and repair-sector viability outweighed those scale benefits.
However, IAG will ask the competition regulator to reassess its $1.35 billion RAC WA purchase proposla under new merger rules taking effect in January.
Those rules are not simply a change of process; they represent a fundamental shift in who holds the pen on big deals.
Under the current system, notification has been largely voluntary and “informal” reviews common, with the courts ultimately deciding contested mergers. Under the new merger control regime, Australia is moving “from the current judicial enforcement model to a primarily administrative model”, with the ACCC as the central decision‑maker. For acquisitions above certain monetary and control thresholds, notification to the ACCC will be mandatory and suspensory – businesses “must notify the ACCC and wait for approval before their proposed acquisition can proceed.”
For IAG, there is still the critical threshold question – does this deal substantially lessen competition in WA motor? The ACCC has already signalled its concern.
To have any chance under the new regime, insiders say IAG would need to come back with a meaningfully different proposal: potentially tougher undertakings around pricing, firewalls on data sharing between RAC membership and insurance, and guarantees on the independence and access of repair networks. Even then, with the new rules “designed to strengthen Australia’s merger control and provide more certainty and transparency” around high‑impact deals, a simple re‑run of the original structure appears unlikely to clear.
In a statement responding to the ACCC’s decision last week, the giant insurer said both IAG and RAC are committed to delivering competitive and accessible insurance products.
“As part of the alliance we have committed to staying local, investing in enhancements to the RAC member experience and continuing to deliver high quality and competitive insurance products and services,” said IAG in a statement released on the ASX.
For now, brokers in WA will continue to place motor into a market that remains more competitive than it might have been. The bigger question is whether this marks the high‑water mark for consolidation between motoring clubs and major insurers – at least in states where a single alliance would dominate private motor.
With a tougher, more transparent merger regime on the way, any future mergers will likely have to be structured with competition risk front and centre. For brokers and their clients, that should mean fewer surprises – and more opportunities to have their say – before the next mega‑merger reshapes their local market.
