The trio is made up of Kimberley Smith Contracting, Winun Ngari Aboriginal Corporation and Walyarra Enterprises.

Kimberley Smith of Kimberley Smith Contracting provides on-site supervision of the workers. Winun Ngari Aboriginal Corporation provides up to 10 local Aboriginal labourers to assist with laying the matting, wire mattresses, and placement of stones within the wire structure. These labourers double as traffic controllers to ensure the traffic management plan is implemented while working on-site.

Walyarra Enterprises provides equipment such as a digger, operated by owner Trent Haewera, and a loader. Gabion works commenced in late 2024, with then site project engineer, Mr Zaghum Pervaz overseeing the works.

“I haven’t seen a more hard-working supervisor, than Kimberley. We had to slow him down a bit because it was too hot, and the other workers were getting drained,” Zaghum shared.

In 2025, twelve workers returned to site and all are local Aboriginal men except for the loader operator and the Main Roads’ site supervisor. This small roadworks crew consists of 85% Aboriginal workers and 100% work packages awarded to Aboriginal businesses. The benefits from these works will flow back into local Aboriginal families and into the town of Derby. Main Roads’ commitment to Aboriginal participation continues to meet the Region’s set targets.
