Bowen Coking Coal Walks Away From Bluff Mine, Leaving Rehabilitation to Queensland Government

A mothballed coal mine in central Queensland has officially been abandoned, leaving the state government responsible for managing the site and its future rehabilitation.

The Bluff coal mine, located about 175 kilometres west of Rockhampton, was operated by Bowen Coking Coal before the company entered financial difficulties. The mine had been mothballed since late 2023 after coal prices and operating conditions made continued production uneconomic.

In July 2025, Bowen Coking Coal entered voluntary administration as the company faced financial pressure from falling coal prices, rising production costs and debts to major creditors. About 500 jobs connected to its broader Burton Coal Complex were put at risk at the time.

After efforts to sell the Bluff mine failed, liquidators recently disclaimed the mining lease, environmental authority and exploration permits associated with the 1,100-hectare site. As a result, responsibility for dealing with the abandoned mine has passed to the Queensland government’s Abandoned Mine Lands Program.

The situation has raised concerns about who will pay for the rehabilitation of the site.

Queensland introduced a financial provisioning scheme in 2019 requiring mining companies to provide financial security to help cover rehabilitation costs if a mine closes. According to The Guardian, a mine the size of Bluff would have been expected to provide approximately A$10 million in financial assurance, while the Queensland government has estimated the cost of rehabilitating the site at around A$12.3 million. The government has not disclosed the specific amount of financial assurance held for Bluff.

The abandoned mine has also affected the surrounding farmland.

Cattle farmer Patricia Goodwin, whose property overlaps the mining area, has raised concerns about damaged roads, erosion, watercourses and the condition of the land. She has also questioned who will address potential environmental problems associated with the abandoned open-cut mine.

Bluff’s history dates back several years. The mine began operating in 2019 under Chinese-owned miner Carabella Resources. It was subsequently placed into care and maintenance after low coal prices, before Bowen Coking Coal acquired the operation from receivers in 2021. Bowen later restarted the mine, but production was suspended again in November 2023.

The Queensland government is now reviewing aspects of its mining rehabilitation laws. The case has become part of a broader debate over how abandoned mines should be managed and how governments can ensure that rehabilitation costs do not ultimately fall on taxpayers when mining companies become insolvent.

For the Bluff community and nearby landholders, the immediate question is what happens to the mine site next — and whether the financial resources available will be sufficient to restore the land.
