Develop
Our environmental specialists and operational teams use optimised designs as the foundation for progressive rehabilitation development and delivery.
Our team embraces technology and employs a range of innovations such as semi-autonomous dozers for bulk reshaping, HPGPS for machine guidance, real-time monitoring and conformance analysis, survey updates into our 3D GIS platform and drones for seeding and fertilisation.
Our capabilities include:
• Bulk profiling and shaping of mine spoil
• Construction of water management systems
• Erosion and sediment management systems

• Tailored revegetation programs
Deliver
Our delivery is underpinned by smart, rigorous processes that support environmental, social and governance excellence.
Our specialists accurately monitor rehabilitation success, reviewing vegetation health and diversity, and identifying erosion, using drones to capture footage of rehabilitated areas.
Technology cost-effectively provides a complete overview of large areas of land, delivering an accurate picture of rehabilitation performance. Clients gain a strong body of evidence of their rehabilitation outcomes, supporting progressive certification of rehabilitated land and reducing ongoing rehabilitation liabilities.

Case Study
Closing the loop at Muswellbrook
Thiess Rehabilitation completed 156 hectares of land restoration works at the Muswellbrook mine in 2025, completing a lifecycle of work after the Thiess Brothers were awarded the initial mining contract at the project in 1944.
The rehabilitation works included engineering, design, geotechnical control, bulk earthworks, civil works, and seeding with native species and improved pasture. By optimising the reference design and applying effective risk controls, the team reduced material movement by 20%, achieved cost savings, and met design tolerances using a quality control approach recognised by the New South Wales Resource Regulator as leading practice.
Sustainability is at the heart of our business
For Thiess this means integrating environmental, social and governance (ESG) considerations into our decision-making, every day.
