As global demand for transition-critical metals accelerates, experts remain divided over whether the energy transition signals the start of a mining supercycle for Australia.
The definition of when a boom becomes a supercycle is contentious. Like the boiling frog metaphor, the shift occurs so gradually that industry participants often realise they are in a supercycle only after it has begun.
The worldwide move toward electrification is driving rapid demand growth for metals essential to batteries, power grids, and renewable energy infrastructure.
Copper, lithium, nickel, and rare earth elements are now central to low-carbon technologies.
For resource-rich Australia, this transition has ignited a familiar debate: does the current critical minerals boom mark the beginning of a new mining supercycle?
Supercycles typically align with major structural changes in the global economy.
Australia’s last mining supercycle stemmed from China’s massive infrastructure expansion in the early 2000s, which lifted Australian iron ore exports from 26 million tonnes in 1999 to 305 million tonnes by 2011.
Today, green infrastructure is the driver.
The International Energy Agency projects the global market for critical energy transition minerals could grow from US$320 billion in 2022 to US$770 billion by 2040.
These figures have led some analysts to argue the mining sector may already be entering the early stages of another prolonged commodities cycle, though the slippery definition of supercycle makes certainty difficult.
Allan Trench, a mineral economist and professor at the University of Western Australia, notes the phrase ‘stronger for longer’ but adds that it is hard to argue the world economy is currently overheating.
The core question is whether battery production, grid expansions, and renewables infrastructure can bolster Australia’s minerals exports enough, for long enough, to constitute a supercycle.
Michael Tamvakis, professor of commodity economics and finance at Bayes Business School, calls the timing the million-dollar question.
In his view, key indicators are scale and duration.
Year-on-year increases of 25 to 50 per cent that continue rising suggest a supercycle, though price spikes happen routinely.
Tamvakis says price levels need to stay high for at least three years, with five years being ideal.
Trench argues for something more sustained, suggesting a decade up and a decade down pattern.
The 2025 Critical Mineral Outlook from the International Energy Agency tracks a 28.9 per cent increase in copper demand between 2021 and 2024.
Lithium demand rose 357.1 per cent over the same period, while nickel increased 148.7 per cent, cobalt 91.8 per cent, graphite 209 per cent, and rare earths 72.7 per cent.
Forecasts indicate the trend will continue. Between 2024 and 2040, cleantech copper demand is expected to rise 57.19 per cent, compared with 15.78 per cent growth in other sectors.
Lithium demand from cleantech is projected to increase by 532 per cent, while nickel demand could rise by 323.7 per cent.
JP Morgan published an article last year stating the clean technology transition is igniting a new supercycle in critical commodities, with natural resource companies emerging as winners.
However, TS Lombard found that favourable supply dynamics, rather than demand alone, have been the primary driver of recent price strength, offering reason to lean against supercycle narratives at this stage.
Australia has begun positioning itself to benefit.
The government invested AU$6.6 billion in domestic mining projects between 2019 and 2024, while the Critical Minerals Strategy 2023–2030 aims to expand processing capacity.
GlobalData estimates Australian copper production could increase by 51 per cent between 2025 and 2030, with lithium rising 37.3 per cent and cobalt 110.5 per cent.
Australia’s lithium production increased 14 per cent in 2024 compared to 2023, securing its position as the world’s largest producer.
However, copper development and downstream manufacturing remain slower to scale. Australia ranked eighth globally in copper production in 2024 despite holding third-place reserves.
Whether the current demand surge develops into a sustained commodity supercycle will depend on how quickly the energy transition unfolds and how effectively Australia’s mining industry responds.
Time will tell definitively, though possibly not until the industry reaches the bust chapter of the sequence.
