WA resources sector decade-high investment: project workload signals for engineers
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Western Australia’s resources sector delivered $226 billion in mineral and petroleum sales in 2025, a decade-high investment year driven by record iron ore export volumes and all-time high gold revenue from operations such as the Super Pit. The sector supported more than 136,000 full-time equivalent on-site mining jobs, signalling sustained demand for mine development, brownfield expansions and associated infrastructure. Contractors can expect continued workload in pit optimisation, haul road upgrades and processing plant debottlenecking as operators push existing iron ore and gold assets harder.
Technical Brief
- Mineral and petroleum sales across WA totalled $226 billion in 2025, per state reporting.
- More than 136,000 full-time equivalent on-site mining roles were recorded across WA operations in 2025.
- Petroleum projects are included in the sales total, indicating concurrent offshore and onshore hydrocarbons activity.
- State-level reporting cadence enables year-on-year benchmarking of capex cycles for WA mining assets.
- For contractors, the quantified jobs base signals multi-year continuity of site-based construction and maintenance demand.
Our Take
Western Australia dominates our iron ore and gold coverage within the 1177 Mining stories, so decade‑high 2025 investment signals that existing hubs like the Super Pit are likely to compete harder with emerging gold targets in states such as Victoria, which is aiming for one million ounces annually by 2035 in the 22 May 2026 piece.
Sustained iron ore and gold revenues in Western Australia give the WA Government more fiscal room to back enabling infrastructure and approvals, which in turn supports the kind of remote-operations and automation ecosystem highlighted in our CSIRO-focused coverage from 20 April 2026.
