Diesel Fuel Tax Credit scheme: operating cost impacts for Australian mines
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Mining industry bodies including the Minerals Council of Australia are pushing back against a proposed cut to the federal Diesel Fuel Tax Credit scheme, which currently rebates most of the 48.8c/L fuel excise for off‑road uses such as haul trucks and mine power generation. They argue removing or reducing the credit would sharply increase operating costs for remote open‑cut and underground sites reliant on high‑horsepower diesel fleets and off‑grid generators. Industry groups warn this could accelerate mine closures, defer brownfield expansions and undermine investment in new projects.
Technical Brief
- Industry bodies stress that diesel remains the only practical energy source for many heavy‑haul applications.
- They also argue grid connection or large‑scale renewables plus storage are not yet technically or commercially substitutable.
- Debate is framed as directly affecting project feasibility assessments and bankability for new and expansion mines.
Our Take
Within our 116 Policy stories, relatively few focus on New South Wales specifically, so any change to diesel fuel tax credits there would be watched closely by project developers using NSW as a benchmark for east-coast operating costs.
For Australia-based Projects coverage in our database, diesel is still the dominant energy input for mobile fleets and remote power, so adjustments to fuel tax credits would likely flow straight into feasibility assumptions and cut-off grade calculations for new mines.
Because this piece sits in the Projects-tagged Policy stream rather than pure fiscal commentary, it signals that operators in Australia are treating diesel tax settings as a material project risk alongside approvals and heritage conditions, not just a background cost item.
