The statistics showed that demand for NSW coal in Japan, Korea, Taiwan and China increased by 1.7%, 8.7%, 14% and 22% respectively over the last financial year.

China has been the second largest market for the state’s coal exports.

NSW Minerals Council CEO Stephen Galilee said: "Coal is our State’s most valuable export commodity so it’s good news for the NSW economy that demand for coal is growing steadily across all our main export markets.

"NSW coal mining has been doing it tough with over 4,000 job losses in the last two years and a broken NSW planning system.

"It is therefore encouraging to see demand for NSW coal rising significantly across our major and emerging markets."

The NSW government has recently announced plans to cut down planning assessment timeframes for major mining projects, to attract investment and create jobs in the state.
