How long will WA's resources boom actually last? What the numbers say about job security

Anyone weighing up a long-term career in WA resources has, at some point, asked a version of the same question: is this an industry with decades left in it, or one that could wind down before a 20-year-old apprentice reaches retirement?

The CME's Unearthing Potential report doesn't answer that with a single number, deliberately so, but it gives a far more detailed basis for the question than most public commentary does. Here's what it actually says about the runway ahead.

The headline modelling runs to 2100, but that's the ceiling, not a promise

The report's central scenario models production out to 2100, a 75-year horizon. That's not because analysts expect every mine to still be operating in 75 years; it's because the "production horizon" for each commodity is defined as the lower of 75 years or the estimated number of years the identified saleable resource could support production at current rates. In other words, 75 years is a cap, not a forecast, some commodities will be depleted well before then under the modelling, others could theoretically run longer than 75 years but are capped at that figure for consistency.

Crucially, the resource base being measured is what's called Economic Demonstrated Resources (EDR) for minerals, and current reserve estimates for petroleum. EDR is a nationally recognised measure of resources that are known, sufficiently explored, and considered economically extractable under today's conditions. It deliberately excludes undiscovered deposits, resources that aren't yet commercially proven, and, the report specifically calls this out, unconventional oil and gas potential in the Canning Basin, including the Lower Goldwyer Shale. That means the 75-year figure is a floor built on what we already know is there, not a ceiling on what might eventually be found. Given WA's exploration history, that's a meaningful distinction: the identified resource base has grown for decades as exploration and technology have advanced, and there's no reason to assume that stops now, the report notes estimates could rise further with future discoveries or improved recovery technology.

Three scenarios, one common thread

The report tests three development scenarios, and all three assume most, not all, of the identified resource base gets developed:

Even in the low-case scenario, 60% of WA's currently identified resources are assumed to be developed, reinforcing that the debate isn't really "will this run out soon," it's "how much of what we already know is down there will actually get built into projects," which depends on investment, infrastructure, workforce capacity, approvals timelines and global commodity markets, all factors largely within Australia's and WA's control, unlike commodity prices and global demand, which aren't.

What a shorter time horizon looks like

The report also models results to 2050, a 25-year view, for anyone who wants a more career-relevant timeframe than "to 2100." Under that shorter horizon, the central scenario still produces:

• $5.5 trillion in saleable product value
• $1.3 trillion in cumulative economic activity
• $905 billion in government revenue
• $718 billion in total wages
• $305 billion in capital expenditure and $1.5 trillion in operating expenditure

Average annual employment, 165,000 construction FTEs and 158,000 operational FTEs, doesn't change between the 25-year and 75-year versions, because those are yearly averages, not cumulative totals. What that really tells a jobseeker is this: on the report's own numbers, the next 25 years alone look almost as strong, employment-wise, as the next 75.

Momentum, not a museum piece

It's also worth reading the modelling alongside what's actually happening on the ground. The WA Government's own project pipeline update, released the same week as the CME report, pointed to more than $50 billion in major projects currently under construction or committed, including Scarborough, Crux and Jansz-Io Compression in LNG, Western Ridge and Brockman Syncline 1 in iron ore, and the Eneabba Rare Earths Refinery and Mt Holland expansion in critical minerals. Industry investment hit $34 billion in 2025, a decade-high. That's not the profile of a sector running down the clock; it's one still committing fresh capital to new, multi-decade assets.

The caveat

None of this should be read as a guarantee. The report is explicit that its estimates are "indicative opportunity estimates, not forecasts," and that actual outcomes depend on commodity prices, global demand, technology, project economics, approvals and investment conditions, many of which are outside any one company's, or even WA's, control. The report also doesn't predict which specific projects will proceed or when.

But for someone asking "will there be a resources industry in WA worth building a 30- or 40-year career in?", the honest answer, on the best current evidence, is yes. The identified resource base alone, using only what's already been found and proven, supports multiple decades of production under every scenario modelled, before you even count what hasn't been discovered yet.
