Output and sales moved in different directions
Whitehaven Coal’s September 2026 quarterly production report, published on 23 October, recorded managed run-of-mine production of 11.0 million tonnes. That was 3% above the June quarter and 22% above the same period a year earlier. Equity sales of produced coal were 6.0 million tonnes, down 5% on the June quarter. The company attributed the lower sales figure to reduced vessel throughput following export-terminal disruptions at Queensland’s RG Tanna terminal and at PWCS in New South Wales. The release says the slippage is expected to unwind in the December quarter; that is a company expectation, not a completed recovery.
Costs and achieved prices
The company put its September-quarter unit cost at the low end of its FY27 guidance range of A$132–147 per tonne. Its average achieved price was A$226 per tonne, 2% higher than in the June quarter and 20% higher than a year earlier. Net debt stood at about A$1.4 billion at 30 September. Whitehaven said sales slippage and elevated inventories had a temporary effect on that position and were expected to unwind during the December quarter. These figures describe the company’s managed production, sales and financial position; they do not measure Australia-wide coal output or export performance.
Queensland and New South Wales detail
Queensland operations produced 5.5 million tonnes of managed run-of-mine coal, 4% below the June quarter. Equity sales were 2.8 million tonnes, down 12%, which Whitehaven linked to poor terminal performance at RG Tanna. The average achieved Queensland price was A$257 per tonne. New South Wales operations also produced 5.5 million tonnes, up 10% from the preceding quarter, while equity sales rose 2% to 3.2 million tonnes. The company reported an average achieved price of A$198 per tonne in New South Wales. Regional results therefore differed: terminal constraints were especially visible in Queensland sales, while NSW output and sales both increased.
Analysis and limits
The quarter illustrates how mine output and export sales can diverge when port or vessel capacity is disrupted. Producing coal does not create revenue at the same moment if it cannot be loaded and shipped, so the quarterly timing of sales can affect inventories, cash conversion and reported debt. Whitehaven’s forecast that deferred sales will recover is prospective and depends on subsequent terminal throughput; the October report cannot establish whether that happened. Nor does one producer’s experience prove a system-wide Australian port bottleneck. For power and materials planners, the practical signal is to track mine production alongside loading and shipping data rather than treating production tonnage as equivalent to delivered supply.
