The Australian Greens are pushing for a fundamental shift in how the nation’s natural gas wealth is taxed, arguing that the current fiscal framework allows multinational energy giants to pay a lower effective tax rate than essential workers. The proposal centers on a significant revenue-sharing model designed to redirect profits from the extraction of fossil fuels toward public services and climate transition initiatives.
At the heart of the debate is a proposal for a 50 percent tax on all gas export revenue. This policy shift aims to address what the party describes as a systemic imbalance in the tax code, where the marginal tax rates for high-earning individuals—such as nurses or teachers—can exceed the effective rates paid by corporations extracting billions of dollars in value from Australian soil.
The push comes amid ongoing volatility in global energy markets and a domestic cost-of-living crisis. By targeting the top line of export revenue rather than just net profits, the Greens intend to close loopholes that allow companies to use complex accounting and depreciation schedules to reduce their taxable income, a practice often referred to as “profit shifting.”
The Economic Logic of a Revenue Tax
For those of us who have spent years analyzing market structures, the distinction between a profit tax and a revenue tax is critical. Most corporate taxes are levied on profits—what remains after expenses are deducted. However, the Greens’ proposal targets the gross revenue generated from exports, ensuring a fixed percentage of every dollar earned from gas sales enters the public treasury regardless of the company’s reported internal costs.
This approach is designed to capture “windfall profits,” which occur when global price spikes—often driven by geopolitical instability—drive revenues far beyond the cost of production. The party argues that since these resources are national assets, the public should be the primary beneficiary of price surges rather than private shareholders.
The disparity in tax burdens has become a central talking point for the party. By contrasting the tax obligations of a nurse with those of a gas corporation, the proposal frames the issue not just as an environmental necessity, but as a matter of basic fiscal fairness and social equity.
Projected Impact and Public Funding
Research from the Greens’ think tank suggests that the current tax regime significantly under-represents the true value of the resources being exported. By implementing a 50 percent revenue tax, the government could potentially generate billions in additional annual funding. These funds are earmarked for a “Green Transition” fund, aimed at accelerating the rollout of renewable energy and providing a safety net for workers in the fossil fuel industry.
The stakeholders affected by this proposal are diverse and their interests often clash:
- Energy Corporations: Likely to argue that such a high tax rate would discourage foreign investment and craft Australian projects uncompetitive compared to other global LNG hubs.
- Public Sector Workers: Seen as the primary beneficiaries of the redirected funds, which the Greens argue should be used to bolster healthcare and education.
- The Federal Treasury: Tasked with balancing the immediate gain of increased revenue against the potential risk of reduced capital expenditure in the resource sector.
To understand the scale of the proposed shift, consider the current landscape of resource taxation in Australia. While the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) provides data on the economic contribution of the gas sector, the actual “effective” tax rate—the amount paid relative to total revenue—is often much lower than the statutory corporate rate of 30 percent.
Comparative Tax Pressure
| Feature | Current System | Greens’ Proposal |
|---|---|---|
| Tax Basis | Net Profit (after deductions) | Gross Export Revenue |
| Primary Goal | Corporate Income Tax | Resource Rent Capture |
| Impact of Costs | Reduces tax liability | No effect on tax liability |
| Target Rate | Variable (Effective rate) | 50% of Revenue |
Challenges to Implementation
Implementing a revenue-based tax is not without significant legal and economic hurdles. Many gas projects are governed by long-term Production Sharing Agreements (PSAs) or stability clauses that protect investors from sudden changes in fiscal regimes. A sudden shift to a 50 percent revenue tax could trigger international arbitration or claims of “indirect expropriation” under bilateral investment treaties.
critics argue that a revenue tax ignores the massive upfront capital expenditure required to build LNG plants and pipelines. If a company is taxed 50 percent of its revenue before it recovers its multi-billion dollar investment, the internal rate of return (IRR) for new projects could drop below the threshold required to attract global capital.
Despite these challenges, the proposal reflects a growing global trend toward “windfall taxes.” Similar measures have been debated or implemented in the United Kingdom and the European Union to curb the excess profits of energy companies during the energy crisis following the invasion of Ukraine.

The next critical step for this proposal will be its introduction and debate during the upcoming parliamentary budget reviews, where the Greens are expected to use their balance of power in the Senate to push for these reforms as a condition for supporting government legislation.
