Australia is the world's third largest LNG exporter.[1] This page shows, in real time, what the public actually collects in Petroleum Resource Rent Tax[2] against what a flat 25 percent export tax on gas would raise instead.

The industry warns a tax would crush investment. Move the slider to see just how much profit is left to flow into shareholders' pockets. In the 2024/25 financial year, Australia's gas extraction sector earned an estimated $35 billion in profit before tax[8] on $65 billion in gas exports.[1] Even with a 25 percent export tax, the industry walks away with a massive $19 billion in gas profit.
The 2024/25 financial year is the most recent year we have complete revenue and profit data for. The ABS has not yet published industry profit figures for 2025/26. That said, gas exports fell to $60 billion in calendar 2025, and profits will likely have fallen too.
According to DFAT, gas export revenue for the 2025/26 financial year fell to $55.4 billion.[1] Assuming the same profit margin as in 2024/25, we estimate gas export profits of approximately $29.9 billion. A 25% export tax would bring about $13.9 billion in tax revenue back to the Australian people, leaving around $16.1 billion in gas company profit.[8]
Revenue is the money coming in. Add up every dollar made from selling gas overseas for an entire year, and you get total export revenue, which was about $60 billion in 2025, down from $67 billion in 2024.[1]
But revenue is not money in the bank. The companies still have to pay for drilling rigs, ships, processing plants, wages, fuel, interest on loans, and so on. A 25% export tax would apply to the revenue, the same way GST applies to a coffee. It is calculated off the top, before any costs come out.
Profit is what is left over after every bill is paid. The drilling rigs, the ships, the processing plants, the staff, the equipment, the lot. Whatever remains is profit. It is the money the company gets to keep, and in the 2024/25 financial year, Australian gas extraction generated an estimated $35 billion in gas-attributable profit.[8]
Profit is how a company grows and rewards its shareholders. It funds reinvestment, research and development. Without it a business cannot remain operational. As we’ve seen, the proposed 25% export tax still leaves a lot of profit in the bank.
