BUMA Australia Pty Ltd, a wholly owned subsidiary of PT Bukit Makmur Mandiri Utama (BUMA), under PT BUMA Internasional Grup Tbk, has announced a multi-year contract extension valued at approximately A$740 million with Blackwater Operations Pty Ltd, a subsidiary of Whitehaven Coal Mining Ltd.
The extension secures BUMA Australia’s operations at the Blackwater Mine in Central Queensland’s Bowen Basin, one of Australia’s largest open-cut metallurgical coal operations, through to June 2030, cementing BUMA Australia’s role as a long-term partner delivering extensive pre-strip operations at the site.
Johan Ballot, CEO of BUMA Australia, stated: “This extension underscores Whitehaven’s confidence in BUMA Australia to deliver safely and efficiently at scale across one of Queensland’s largest metallurgical-coal operations. Our understanding of site conditions, strong local team, and consistent results enable us to sustain productivity while contributing to the long-term success of the Blackwater Mine.”
Located 20 kilometres south of the township of Blackwater, the mine spans an 80-kilometre strike length across multiple pits and remains a key economic driver in Central Queensland. BUMA Australia, together with its predecessor operations, has delivered mining services at Blackwater since 2012, employing approximately 390 permanent personnel and drawing on experience with the site’s complex geology. The company upholds industry-leading safety performance and says it leverages advanced monitoring systems, both third party and in-house for predictive maintenance and real-time fleet optimisation.
“This renewed partnership with Whitehaven strengthens our portfolio of Tier-1 operations and reinforces BUMA’s reputation for delivering sustainable, world-class performance,” said Iwan Fuad Salim, Director of BUMA International Group. “It enhances the Group’s earnings visibility and cash-flow stability through long-term partnerships with high-quality clients, while supporting our broader growth and diversification strategy.”
Beyond operations, BUMA Australia continues to generate local and social value across Central Queensland. At Blackwater, the company actively supports local initiatives through job creation, skills training, and its dedicated First Nations employment program. Its sponsorship of regional sporting teams and community events continues to foster local connections and contributes to long-term resilience.
The BUMA fleet at Blackwater it lists as having one Hitachi EX8000 and one EX3600 excavator; three Caterpillar 6060 excavators; 13 Komatsu 930E haul trucks; 15 Caterpillar 789 haul trucks; one Caterpillar 16M and three 18M graders; four Caterpillar D10 and five D11 dozers; and four Caterpillar 785 water trucks.
