In the wake of the recent federal budget, the debate has intensified over how everyday Australians build wealth and how the nation manages its vast natural resources.
While citizens shoulder a significant share of the structural tax burden, Australia’s dual revenue system of state royalties and the federal Petroleum Resource Rent Tax (PRRT) faces ongoing scrutiny over its efficiency in capturing public revenue.
Australia is blessed with an abundance of iron ore, coal, liquefied natural gas (LNG), and the critical minerals desperately needed for the global energy transition. However, allowing multinational energy giants to offset massive development costs and carry forward losses has meant that some of the largest LNG exporters pay little to no resource rent tax, even during periods of record global prices. This is despite recent federal reforms capping PRRT deductions at 90% of a project’s assessable income, ensuring these projects pay some tax sooner.
State royalties do the heavy fiscal lifting but are primarily tied to bulk export volumes rather than capturing “super profits” during commodity booms. Queensland altered this dynamic in 2022 by introducing progressive coal royalties scaling up to 40% during price spikes. This proactive approach is not without its friction. The Queensland tax hike led mining giants like BHP to publicly pause regional investments, underscoring the real-world tension between capturing sovereign wealth and navigating industry blowback.
To add to the economic complexity, these same extraction industries benefit from billions of dollars in public subsidies, namely the highly contested fuel tax rebate, which critics argue results in taxpayers supporting the export of national assets.
Look north to Norway, and a radically different philosophy emerges. Norway recognised decades ago that oil and gas are non-renewable. That is, once extracted, they are gone forever. To ensure this temporary windfall translated into permanent national prosperity, they capture resource value through a 78% total tax rate on petroleum extraction and mandated state co-investment in projects. This approach has cultivated a sovereign wealth fund valued at roughly US$2.2 trillion, alleviating pressure on other domestic tax areas.
But it’s not just about taxation, it’s also about industrial strategy. Consider Indonesia, a nation that took a decisive approach to its own resource endowment. Recognising its critical role in the electric vehicle supply chain, Indonesia did not just ask for more tax on its raw nickel; in 2020 it banned export altogether.
The message to foreign multinationals was hard-nosed and uncompromising. If you want our nickel, you must build your smelters and processing plants here. This protectionist gamble forced a massive influx of foreign capital, transitioning Indonesia from a mere exporter of dirt to a downstream battery manufacturing player.
While Indonesia’s strategy demonstrated immense ambition to climb the value chain, it introduced significant sovereign risk that can frighten off foreign capital, alongside complex environmental trade-offs. Furthermore, its success relied heavily on cheap labour and less stringent environmental standards, advantages Australia cannot and should not replicate. Instead, an Australian downstream strategy must compete on advanced, automated manufacturing rather than blunt processing.
In an increasingly fractured global landscape, minerals are no longer just commodities, they are strategic geopolitical leverage. China has masterfully demonstrated this by tightly controlling export licences for rare earths and critical minerals such as gallium and antimony to protect domestic high-tech manufacturing and maintain leverage over global defence and semiconductor supply chains.
Australia boasts some of the world’s largest reserves of these exact critical minerals, however, the domestic strategy remains largely centred on a high-volume, low-margin “dig and ship” mentality, exporting assets in their rawest form and passing value-add leverage to offshore processors.
As the global energy transition accelerates, Australia stands at a pivotal crossroads. We hold the lithium, copper, cobalt, and rare earths the 21st century needs. The nation faces a mature, necessary conversation regarding how it manages its finite inheritance. Striking a delicate balance between a stable investment climate and a robust public return is vital to ensure future generations are not left with empty mines and an unsustainable tax burden.
