Built on Country & Driven by Capability
Willimara brings together over two decades of Western Australian civil contracting expertise with Indigenous leadership and cultural responsibility.
A Powerful Synergy
Established in 2026, Willimara is a strategic joint venture between the Karlayura Group and the HAS Family of Companies (HAS Earthmoving and Retco Holdings).
We combine Karlayura’s authentic Indigenous knowledge and connection to Country with the operational power of industry veterans. This is not a startup; it is a partnership of proven companies. We provide Tier 1 mining and resource clients with a highly capable, socially responsible contracting partner, bridging the gap between decades of on-the-ground expertise and a profound commitment to Indigenous empowerment.
