Simplify's take

What believers are saying

  • July 2026 CIMIC buyback removed Elliott, simplifying strategy and boosting portfolio flexibility.
  • October 2026 Mongolia wins add five-year Oyu Tolgoi and Ukhaa Khudag work.
  • September 2026 Caravel MoU and August 2026 Mechatronix deal widen the 2027 pipeline.

What critics are saying

  • Prominent Hill ended in September 2026, proving Thiess loses large mature contracts.
  • Thermal coal revenue fell to 25.9% in 2025, pressuring margins if renewals slip.
  • A severe Oyu Tolgoi disruption would damage Thiess' global credibility and contract bid rates.

What makes Thiess unique

  • Full ownership under CIMIC gives Thiess stronger capital access and procurement leverage.
  • Thiess spans open-cut, underground, asset management, and rehabilitation across Australia, Asia, and the Americas.
  • Mongolia, Yilgarn, and Caravel show breadth across copper, iron ore, gold, and coal.

Phoebe Solon Updated November 6, 2026 - 3.08pm (AWST), first published at 2.00pm (AWST) AEMEE Winners - MDM Mining & Civil - Indigenous Business of the Year. Image: Tallulah Pfingst. Indigenous businesses, entrepreneurs and industry were recognised for their outstanding contributions to Australia's resources sector, as the 19th Annual Aboriginal Enterprises in Mining, Energy and Exploration (AEMEE) Conference came to a glamorous close in Rubibi (Broome). The two-day conference concluded on Thursday, November 5, with a night of celebrations at the 2026 AEMEE National Awards celebrating Indigenous leadership, business growth and partnerships creating economic opportunities for Aboriginal and Torres Strait Islander people. Held under the theme The Next Era: Leadership. Ownership. The Future., the conference brought together Traditional Owners, Indigenous businesses, industry leaders and government representatives to discuss the future of Indigenous economic participation across Australia's mining, energy and exploration sectors. AEMEE chief executive Jyi Lawton said the conference provided an important opportunity for Indigenous businesses and major resources companies to have meaningful conversations about the industry's future. "The past few days have been incredibly powerful. We've brought together Traditional Owners, Indigenous businesses and some of the country's largest resources companies to have meaningful conversations about where we are, where we're heading and what the next era of Indigenous business looks like," Mr Lawton said. "But tonight is about recognising the people and businesses who are already out there doing the work. "Across the country, Indigenous businesses are delivering major projects, employing our people, building new industries and demonstrating that we have the capability to operate at every level of the resources sector. "These awards are about recognising those achievements, but they're also about showing the next generation of Indigenous entrepreneurs and leaders what's possible." Held at Broome Civic Centre, the awards recognised businesses and individuals making significant contributions through employment, training, innovation and commercial partnerships. MDM Mining and Civil took home Indigenous Business of the Year for its growing mining and civil contracting operations across regional and remote Northern Australia. Evolution Mining and Civil was runner-up. Black and White Contracting, established in 2024, received New Indigenous Business of the Year, recognising its rapid growth and delivery of mechanical, electrical and construction services across Western Australia and the Northern Territory. Karlayura General Cranes was runner-up. The Powering Country Award went to Woollahra Group for its national industrial supply and manufacturing operations, while Indigenous Energy Australia and Partners received runner-up recognition. Wajarri-Nanda businessman and Mallard Contracting founder Robby Mallard was named Sector Champion of the Year (Male), recognising his commitment to Aboriginal employment, training and mentoring. Runners-up were Kernon Lalara and Kurt Jaragba, Aquaculture Technicians at Groote Aqua Aboriginal Corporation. Barada Barna Aboriginal Corporation Chairperson Luarna Dynevor received the female award for her leadership in strengthening Traditional Owner commercial opportunities and advocating for Barada Barna people. Nicky Tyson was runner-up. The Collaboration of the Year award recognised AMY Nominees and Thiess for their longstanding partnership supporting employment, workforce development and contracting opportunities for Antakirinja Matu-Yankunytjatjara people. The Judges' Choice Award was shared by Groote Aqua Aboriginal Corporation, recognised for developing an Anindilyakwa-led aquaculture industry on Groote Eylandt, and IMC PKKPE JV Pty Ltd for its mining and civil construction capabilities in the Pilbara and commercial outcomes for PKKP people. KCU also received a Judges' Special Commendation for its contribution to Indigenous business. Mr Lawton said the achievements reflected a broader shift in the role Indigenous businesses were playing across the resources industry. "We're seeing Indigenous businesses move beyond traditional subcontracting opportunities into larger contracts, new industries, more complex projects and stronger commercial relationships," he said. "The next era has to be about Indigenous people having a greater say in decisions, greater ownership of opportunities and a stronger position in the industries operating on our Country. "The businesses and leaders recognised tonight are showing what that future can look like. "And while there's still a lot of work to do, there's also a great deal to celebrate." The 19th Annual AEMEE Conference was held on November 4 and 5, supported by inaugural Legacy Partner Djarindjin Aboriginal Corporation and Djarindjin Airport, Gold Sponsor Rio Tinto and other industry partners.

SSG Indigenous Support Scholarship returns for a second year.

SSG Indigenous Support Scholarship returns for a second year. Jul 31, 2026 - Riley Finnan At Supply Solutions Group (SSG), Supply Solutions Group believe that investing in people creates lasting opportunities. That's why Supply Solutions Group is proud to celebrate the second year of its SSG Indigenous Support Scholarship, recognising exceptional academic achievement and supporting Indigenous Australians as they continue building successful careers in the mining industry. This year's scholarship has been awarded to Daniel, who was selected for his outstanding commitment and academic performance throughout his training with DreamPath, an Indigenous training program for mine haul truck operators. Since completing the program, Daniel has joined Thiess and is continuing to build his career with a clear vision for the future. With aspirations of becoming a supervisor in the mining industry, Daniel has chosen to further his education by undertaking a Work Health and Safety (WHS) course. Through the SSG Indigenous Support Scholarship, Supply Solutions Group is proud to fund his studies and support the next step in his professional journey. The scholarship continues to build on the success of last year's inaugural recipient, Tanayha, who also works with Thiess. Like Daniel, Tanayha Smurthwaite used the scholarship to complete the same qualification while working towards her own leadership goals within the industry. Seeing both recipients continue to advance their careers highlights what this initiative is all about - supporting education, creating opportunity, and helping develop the next generation of Indigenous leaders in mining and construction. Congratulations to Daniel on receiving the 2026 SSG Indigenous Support Scholarship. Supply Solutions Group look forward to following his journey and celebrating his future achievements.
