For years, Australia’s prosperity has been tightly linked to iron ore, a commodity that has powered export earnings, reshaped regions such as Western Australia and tied the country more closely to demand from China. Iron ore mining took off as China began rapidly urbanising around 2005 and that building boom needed massive volumes of steel. Australia happened to have vast, high quality deposits in the Pilbara and the capacity to ramp up supply quickly, transforming state budgets, company profits and the fortunes of local magnates. A relatively small shift in the iron ore price, even by about 10%, still ripples through the federal budget and GDP.
Now the dynamic inside the country’s biggest miner looks very different. Over the latest half year, copper delivered roughly 51% of about $7.9 billion in profit, overtaking iron ore’s contribution of roughly 49%. Five years ago, iron ore accounted for more than four fifths of that same company’s half year earnings. The gap has closed as iron ore prices eased, copper production volumes increased and copper prices jumped by more than 30% in just six months. Industry analysts see two intertwined stories. Iron ore looks past its peak era of super profits while copper is emerging as the new flagship metal driving strategy, investment and future growth.
The outlook for iron ore is clouded by both rising supply and softer demand. New projects in Africa, including a major high grade operation that could eventually equal around a tenth of Australia’s production, are set to push extra tonnes into the market. Brazilian miners are rebuilding output after earlier disruptions and Australian producers are still expanding. On the demand side, the Chinese property sector, once the main engine for steel consumption, has weakened. Growth expectations for China appear to be trending lower and that weighs on long term appetite for construction driven raw materials such as iron ore, even though steel exports from China have so far helped cushion the fall.
Copper, by contrast, sits at the centre of several powerful growth themes. Because it conducts heat and electricity so efficiently, it is essential in electric vehicles, renewable energy systems, power grids, data centres, defence technologies and everyday appliances. As economies electrify and digitise, most forecasters expect copper demand to rise strongly, possibly faster than new supply can be brought on. Many of the world’s largest copper mines are ageing, ore grades are declining and operators are digging deeper at higher cost. New deposits tend to be in geologically rich but politically or operationally complex regions, which adds risk and slows development. Those constraints make future shortages and higher prices look increasingly likely, reinforcing why a diversified resource giant wants more exposure to this metal.
Even so, copper is unlikely to replicate iron ore’s outsized role in Australia’s economy any time soon. Iron ore exports were worth around $120 billion in 2025 while copper exports were closer to $12 billion. Australia supplies about half of the world’s iron ore but only around 6% of global copper, far behind the leading copper producer in South America which controls roughly a quarter of the market. The biggest domestic growth potential lies in large, complex ore bodies in South Australia, including a huge deposit capable of operating for centuries at current extraction rates and containing both copper and significant uranium. Turning that kind of resource into a truly large scale operation has proven technically demanding and repeatedly delayed, which underlines that opportunity does not automatically translate into production.
Looking ahead, Australia still seems set to remain a global resources heavyweight, just with a more mixed portfolio. Iron ore is not disappearing but it may no longer be the unchallenged pillar of national income. The country has already shown it can move quickly when new minerals are in demand, as seen in the rapid rise to the top tier of global lithium suppliers. Government policy currently leans into this strength by backing smelters, refineries and critical minerals projects with concessional finance and other support. The strategy appears to be to evolve the existing resource base, such as iron ore, copper, lithium and rare earths, so it continues to anchor jobs, investment and export earnings through the energy transition even though the exact balance of winners and losers is still unfolding.
