Gojeerah Takaichi Cometh to Destroy Gas Tax

Key Takeaways

• Japan holds ~$40 bn equity in 13 Australian LNG projects.
• 56% of Australian LNG exports are royalty‑free.
• Gas firms earned $74 bn USD windfall profits since Ukraine war.
• Proposed 25% export tax may raise domestic gas prices similarly.
• Japan could supply up to 0.5 mb/d diesel to offset shortages.

Pulse Analysis

Japan’s energy strategy has increasingly leaned on Australian liquefied natural gas, with roughly 40% of its electricity generated from Aussie LNG. The upcoming visit by Prime Minister Sanae Takaichi underscores the interdependence: Japan controls about $39 bn USD in equity stakes across 13 Australian projects, and its strategic oil reserve of 470 million barrels could be tapped to support Australian fuel needs if global supply routes, such as the Straits of Hormuz, remain constrained. This diplomatic overture arrives as Australia wrestles with a proposed 25% gas rentier tax, a policy championed by the Australia Institute to capture revenue from an industry that currently enjoys extensive tax breaks.

The tax debate is fueled by stark data: more than half of Australia’s LNG exports are royalty‑free, and major producers like Santos and INPEX have paid negligible corporate tax despite generating $31 bn and $53 bn USD in sales respectively over the past decade. Since Russia’s invasion of Ukraine, gas exporters have amassed roughly $74 bn USD in windfall profits, yet the proposed levy could push domestic gas prices up by a comparable margin, eroding the competitive advantage that Australian consumers have enjoyed. Comparisons to Qatar, which extracts five times more revenue from similar export volumes, highlight the fiscal gap Australia seeks to close.

If the tax proceeds as drafted, it could trigger higher local gas prices, dampen downstream industries, and strain the political consensus that has kept the sector buoyant. Conversely, delaying or reshaping the levy—perhaps into a fixed‑price export levy—could preserve domestic affordability while still delivering revenue. Japan’s willingness to supply diesel in a potential shortage scenario gives it leverage to negotiate a more nuanced tax structure, turning a fiscal challenge into a strategic partnership that secures energy supplies for both nations.
