June 21, 2022 - Australia's Queensland government has introduced new upper tiers to its coal royalty regime to earn additional revenue from higher prices from 1 July, adding to costs for metallurgical and thermal coal sales at current prices.

Queensland's coal mining firms pay 7pc royalty on the first A$100/t ($69/t) earned, 12.5pc on coal earnings at A$100-150/t and 15pc on earnings beyond A$150/t. From 1 July, mining firms will pay 20pc royalty on prices exceeding A$175/t, 30pc over A$225/t and 40pc over A$300/t. The new rates are progressive, so coal sold at A$310/t will attract a royalty of 40pc on just the top A$10/t, with 30pc on A$75/t, 20pc on A$50/t, 15pc on A$25/t, 12.5pc on A$50/t and 7pc on the remaining A$100/t.

The higher royalty tiers will mostly impact Queensland's metallurgical coal sales. The average hard coking coal export prices have been above A$175/t for five of the last 10 years, according to the Queensland government. Queensland's average thermal coal export prices have only been above A$175/t around 2.5pc of the time in the past decade, with those prices seen only in the past few months, Queensland's budget papers show.

The Queensland treasury has revised its volume forecast down by 10mn t/yr for the 2022-23 financial year ending 30 June to 196mn t/yr from its last forecast released in December because of lower demand and supply associated with a wetter-than-average year. But the treasury expects an increase in revenue next year based on the new upper royalty tiers across hard coking coal, semi-soft coking coal and thermal coal.

Meanwhile, neighbouring New South Wales kept its royalties unchanged at 8.2pc of the value of open-cut mined coal, 7.2pc of underground coal and 6.2pc of deep underground coal.
