Australia spent nearly four years without a single critical minerals project reaching a final investment decision. Then five got the go-ahead between March and June 2026. That cluster, identified in PwC Australia's Can we get serious now? Securing Australia's critical minerals future, could be the most important number on a mining broker's desk this year. It means the pipeline has stopped stalling and started converting and every one of those projects is now making design decisions that will determine what a loss costs for the next twenty years.
Michael Beaumont (pictured), account engineering group manager and senior advisor at global commercial property insurer FM in Australia, has spent more than three decades in mining risk engineering. He watched several Australian booms arrive and has a specific warning about the point in a project's life when risk gets locked in.
"History suggests that resilience is often easiest to justify before construction starts and hardest to retrofit after commissioning," Beaumont said.
The window he described is open now, and not for long. PwC found 907 critical minerals projects nationwide, of which 117 sat in what it calls the investable universe at April 30 2026. Only 13 had reached definitive feasibility study stage. Around 90% of investable projects remain three to six years from a final investment decision and more complex operations - those needing bespoke hydrometallurgical or solvent extraction processing - may take a decade.
For brokers, that spread is the opportunity. A handful of clients are building now. A much larger group is still in study phase, which is precisely where Beaumont's argument bites.
PwC Australia partner Lachy Haynes framed the commercial pressure driving the sector. "Allies are placing a premium on speed to production," Haynes said. "Australia is still a partner of choice, but that only holds if we can bring projects to market faster."
Speed is what makes this a risk conversation rather than a market one. Pressure to reach first production is exactly what pushes resilience decisions down the priority list, and those decisions are the expensive ones to reverse.
The engineering case rests on loss data rather than argument. Beaumont's team analysed more than US$2 billion of mining losses over two decades and found fire remains the largest single source of loss value in the industry, currently sitting at 32% of total gross loss.
What matters for a broker is when the severity of those losses gets decided. Once a plant is built, relocating critical transformers, redesigning conveyor systems, increasing separation between high-value assets or replacing combustible construction materials becomes extremely difficult and expensive.
The questions that determine all of it are unglamorous and practical. Where are critical transformers located? How much separation exists between high-value assets? Is the design introducing unnecessary combustible loading? How will batteries, charging infrastructure and electrical systems be protected? Is there sufficient access for firefighting and maintenance? And if one critical asset is lost, what does recovery actually look like?
Beaumont argued the industry's risk analysis routinely stops short of that last question.
"In my experience, too many projects focus on what might fail and the likelihood of that happening, but not enough time is spent understanding the consequences and what recovery would actually look like if that period of interruption was realised," he said.
Once that discussion is worked through, on his account, the value of engineering, redundancy, strategic spares, fire protection and contingency planning becomes far clearer. Insurance is one part of resilience, not the whole of it.
Beaumont's most practical observation for brokers concerns who is in the room.
Insurance decisions at a mining company frequently sit well away from the people who own operational risk on site. A mine manager or a site engineering manager rarely gets intimately involved in insurance contracts, which means the design questions that determine loss severity are being answered by people who never see the policy and the policy is being bought by people who never see the drawings.
"This is especially important if a lot of the risk/insurance decision making is isolated from the operational risk owners," Beaumont said.
His view is that a broker does not have to run the engineering conversation to be useful. Asking the questions and confirming the mining company has considered them is enough to move the issue in front of the people who can act on it.
There is one further point worth carrying into those conversations. Beaumont noted the risks are broadly similar whether a mineral is classified as critical or not and that ordinary disciplines matter as much as strategic ones. As he put it, more mundane day-to-day management issues, like managing hot work, are just as important in operations whether the product has been deemed critical or not.
Much of the Australian build-out is midstream rather than open pit - refineries, separation circuits, processing plants. PwC identified only eight processing facility projects across the entire pool of 907, and Export Finance Australia has committed an AU$1.65 billion non-recourse facility to Iluka Resources' Eneabba rare earths refinery. In a chain that thin, a single plant outage is not a site problem.
For the five projects that reached a final investment decision this year, some of those decisions are already made. For the 117 in the investable universe, they are not.
