NSW Minerals Council CEO Stephen Galilee said that the demand for the region’s coal has increased by 8% in Korea while exports have surged up to 21% to Taiwan.

Exports from the state have more than doubled to 15.6 million tons over the last nine months in Asian markets, outside Japan and China, especially in India.

NSW coal exports to India have doubled so far over this financial year from 3.2 million tonnes to 7.7 million tonnes.

Galilee said: "Currently, around 80% of coal imported by India is sourced from Indonesia and is predominantly low-grade, high ash coal.

"The move to cleaner coal imports puts NSW in a prime position to benefit from this growing demand for the type of clean thermal coal our state produces.

"This was reflected in a recent speech by India’s head of the Department of Industrial Policy and Promotion, who said that India wanted international miners to send their coal to India, including ‘Australian players, who would bring and receive huge benefits."
