Working Interests in Australia: A 2025 Investor’s Guide

A working interest is a form of direct investment in a resource project—most commonly in mining or oil and gas—where the investor not only shares in the revenue generated but also takes on a proportionate share of the costs and liabilities. Unlike royalty interests (where you simply collect a cut), working interests mean you’re ‘in the trenches’ alongside the operator, sharing profits, losses, and operational decisions.

• Revenue Participation: Investors receive a share of the output (e.g., gold, LNG) after expenses.

• Cost Exposure: You’re responsible for your share of exploration, extraction, and operating costs.

• Operational Influence: Depending on your agreement, you may have a say in key project decisions.

For example, an investor with a 15% working interest in a Queensland coal seam gas project will contribute 15% of the capital and operational expenses, and in return, receive 15% of net production proceeds.

This year, the Australian Taxation Office (ATO) and state regulators have introduced several changes that directly impact working interest holders. Staying compliant isn’t just smart—it’s essential for protecting your investment.

• ATO Rulings: In 2025, the ATO clarified that working interest income must be reported as business income, not passive income. This can impact how losses are offset and how GST applies to project expenses.

• Environmental Bonds: WA and QLD have updated requirements for environmental performance bonds. Working interest holders are now jointly liable for compliance breaches and rehabilitation costs, not just operators.

• Stricter Disclosure: ASIC now requires enhanced disclosure of working interest arrangements in prospectuses and ongoing investor reports, particularly for junior explorers raising capital.

One practical effect: If you’re part of a joint venture in the Pilbara, you’ll need to budget for your share of new environmental levies and ensure all compliance documentation is up to date to avoid penalties or project delays.

Working interests can be highly rewarding, but they’re not for the risk-averse. Unlike shares in listed mining firms, you’re exposed to operational hiccups, commodity price swings, and regulatory changes.

• Upside: When commodity prices surge—as seen with lithium and LNG in early 2025—working interest holders can see outsized returns compared to passive investors. For example, investors in a 2021 WA lithium project saw their distributions triple after a sharp price rally in Q1 2025.

• Downside: If a well comes up dry or a mine faces a shutdown due to environmental breaches, working interest holders still foot their share of the bill. In 2024, a group of private investors in a NSW gas JV faced unexpected remediation costs after new groundwater rules came into force.

It’s vital to conduct thorough due diligence, understand the terms of your joint operating agreement, and budget for contingencies—especially with Australia’s regulatory climate in flux.

If you’re considering a working interest in an Australian project, ask these questions before signing on the dotted line:

• What are the projected capital and operating costs, and how are overruns handled?

• Who is the project operator, and what is their track record?

• How are disputes resolved among joint venturers?

• What environmental and rehabilitation obligations are attached?

• How will 2025 policy updates affect my tax position and compliance responsibilities?

Professional advice is a must. And with increased regulatory scrutiny, transparency and documentation are more important than ever.

Working interests offer a direct—and potentially lucrative—way to participate in Australia’s resource sector, but they’re not for everyone. With 2025’s regulatory changes, investors must be proactive, informed, and ready to shoulder both the rewards and the risks. If you’re seeking exposure to the energy or mining sector beyond the stock market, now is the time to revisit how working interests might fit your strategy—and your risk appetite.
