The contract extension secures BUMA Australia's mining operations at the Blackwater Mine in Queensland's Bowen Basin through June 2030.

The site is one of Australia's largest open-cut metallurgical coal operations. The company will continue to deliver extensive pre-strip mining services at the Blackwater Mine.
The company said that Blackwater Mine remains a key economic driver in Central Queensland, with the company employing about 390 permanent personnel at the site and supporting local communities through job creation, skills training, and First Nations employment initiatives.
