Cullenswood Coal Mine is a small, open-cut mine owned by Cornwall Coal Company, which is a wholly owned subsidiary of Cement Australia, in north-east Tasmania, Australia.[1]

The Cullenswood coal mine began operating in 2002. Cornwall Coal Company owns two other mines in Fingal: Blackwood mine and Huntsman mine. All three coal mines send their product to be processed at Duncan Washery before it is passed along to Tasmanian industries, such as Cement Australia at Railton and Norske Skog at New Norfolk. All of the coal from Cornwall Coal’s mines stay on the island of Tasmania. Cornwall Coal as a whole produces about 500,000 tonnes of ROM coal per year.[2]

Cullenswood mine began as one open cut pit. But by 2010, only about 30,000 tonnes of coal remained at Cullenswood No 1, so Cornwall Coal proposed an addition of Cullenswood No. 2, a new open cut mine near the original. An Environmental Effects report for the proposed expansion wrote that the “planned level of production is likely to be 150,000 tonnes per annum over the life of the deposit, which is expected to be 5-10 years depending on actual production rates.”[3]

Along with that proposal, a study was conducted by Palaris Mining to determine the coal deposits in the newly proposed mine area. They estimated one coal seam within the lease held about 519,000 tonnes of coal and another held about 154,000 tonnes, for a total of about 673,000 tonnes of coal.[4]

Cullenswood No. 2 was approved, but it is unclear exactly when this occurred.[5]

Cornwall then proposed another open pit in 2015, Cullenswood No. 5, which would allow for extraction of 50,000 tonnes of coal per year.[6] The resource at the site is estimated to be approximately 150,000 tonnes, which would allow for a 3 year operation.[7] Though it is unclear when this was approved, it appears by looking at a satellite map that the operation was approved, as coal mine operations are clearly taking place here.


As of 2022, Cornwall has proposed yet another open pit--Cullenswood No. 6 to be located at 6870 Esk Main Road, in St Marys, Tasmania, Australia.[8] Similarly to Cullenswood 5, it would extract up to 50,000 tonnes of raw coal per annum over a 26-hectare area.[8]

If approved, this new mine pit will replace the currently active Cullenswood coal pits when they run out of coal in 2023. Cullenswood 6 is estimated to operate until 2026 or 2027.[9]
