Australia: Coal production in New South Wales falls sharply, supply constraints loom

• NSW coal production down 8% y-o-y in Jan to 16.7 mnt
• Port stocks down 16% y-o-y despite monthly gain

Coal production in the Australian state of New South Wales (NSW) fell sharply in January, according to latest data. Output stood at 16.7 million tonnes (mnt), down 14.8% month-on-month and 8% year-on-year. NSW is a key supplier of high-calorific value coal to Asian markets, including Japan, South Korea and Taiwan.

In January 2026, New South Wales (NSW) recorded a decline in key coal supply indicators on a year-on-year basis. Coal production stood at 16.7 mnt, reflecting an 8% contraction compared to the same period last year.

Mine inventories witnessed a sharper reduction, falling by 28% y-o-y to 9 mnt, indicating tighter stock availability at the pithead level. Similarly, port inventories, including those at Newcastle, declined by 16.3% y-o-y to 3.5 mnt, suggesting moderated stockpiles across the supply chain.

Inventories deplete across the board

Stocks at NSW mines fell to 9 million tonnes in January, down 27.8% month-on-month and 28% year-on-year. The sharp decline suggests that production is not keeping pace with drawdown rates.

Inventories at NSW ports, including the Port of Newcastle – the world’s largest coal export terminal – stood at 3.5 mnt. While this represented a 43.7% increase month-on-month, it was still 16.3% lower y-o-y.

Implications for Asian buyers

Australia is a critical supplier of high-CV coal to Northeast Asian utilities. Falling production and depleted inventories could tighten supply for Japanese, South Korean, and Taiwanese buyers, supporting prices for Newcastle coal.

The drawdown in mine stocks is particularly concerning, as it indicates limited buffer even before reaching export terminals. Any further production disruptions or rise in demand from key buyers could quickly translate into higher FOB prices.

Outlook

The NSW production data for January points to underlying supply tightness. If this trend continues through the first half of 2026, Asian buyers may need to compete more aggressively for available Australian cargoes.

Traders should monitor monthly production updates from NSW and Queensland, as well as inventory levels at Newcastle and other major ports.
