WA mining windfall and budget surplus: royalty and infrastructure signals for miners
Reviewed by Tom Sullivan

30 Second Briefing
Mining royalties of $10.8 billion in 2025–26 have driven Western Australia to forecast a $3.2 billion budget surplus, with iron ore, lithium and gold remaining the dominant revenue sources. The budget papers show iron ore alone still contributes the bulk of royalty income, supported by sustained prices above long‑run assumptions and export volumes near record Pilbara output. For miners, the figures signal continued state reliance on royalty streams, with implications for future changes to royalty rates, approvals resourcing and investment in enabling infrastructure such as ports and heavy‑haul rail.
Technical Brief
- Royalty dependence increases sensitivity to any production disruptions from cyclones, port outages or major pit wall failures.
Our Take
Mining royalties of A$10.8 billion in 2025–26 give Western Australia unusual fiscal headroom compared with other Australian states, which typically rely more heavily on GST and payroll tax, suggesting WA can continue to fund infrastructure that directly supports gold and bulk commodity projects without immediate new imposts on operators.
Gold is one of the more frequently covered commodities in our mining database, and in WA this tends to correlate with sustained brownfields expansion rather than greenfields megaprojects, meaning royalty growth is likely to come from incremental throughput and life extensions at existing operations rather than a wave of new mines.
The stronger WA budget position underpinned by mining royalties aligns with recent coverage of contractors expanding into larger EPC-style packages, signalling that state-backed infrastructure and rehabilitation spending could further deepen the local services ecosystem that gold and other miners in WA depend on for cost and schedule certainty.
