Increasing female representation in assets and maintenance

The Thiess Group is advancing female representation across its global maintenance and mining operations through targeted development pathways and employee-led initiatives.

Women in Maintenance and Assets (WiMA)

The Women in Maintenance and Assets (WiMA) Employee Resource Group (ERG) was established in 2023 in Australia as a grassroots, employee-led network dedicated to connecting, supporting and empowering women within Thiess’ maintenance and asset management workforce in Australia.

Aligned with the Group’s Diversity, Equity and Inclusion Strategy, WiMA delivered engagement initiatives in 2025, including three regional workshops across Western Australia, New South Wales and Queensland, and two virtual sessions. More than 100 participants took part, with attendance increasing 27% in New South Wales compared to 2024, and the first
workshop held in Western Australia with both Thiess and MACA participants.

Workshop feedback remained consistently strong in 2025 with participants reporting increased confidence, stronger peer networks, and greater clarity about career development pathways. Leaders also observed improved team engagement and more frequent discussions about inclusion and development.

As one participant shared: “I thoroughly enjoyed connecting with other women and learning valuable skills I can take back to site. It made me feel part of something
bigger.”

In 2026, WiMA plans to continue to expand its reach and grow Australian participation across Thiess, MACA, PYBAR and RTL, through a mix of centrally organised headline events and supporting regional members organise local events.

Championing female talent in Chile

In South America, Thiess is also investing in the skills pipeline for women in maintenance. At the Innovation, Training, and Technology Centre (ITTEC) in Antofagasta, Thiess hosted Chile’s Minister of Mining, Ms Aurora Williams, to showcase the Mechanical Maintenance Apprentices program – a dedicated pathway for women seeking to enter the mining industry.

Ten participants commenced training in August 2025 at CEFOMIN Antofagasta, a mining and industrial training centre, before joining Thiess’ ITTEC in December for hands-on technical development. Their participation highlights Thiess’ commitment to developing local talent and increasing female representation in mining roles in the region.
