We have gained a reputation for technical innovation, reliability, quality workmanship and professional services across our companies.



KRSP is an equal joint venture between GJ Johnson & Co. and the Marra Worra Worra Aboriginal Corporation. We provide a range of quality services, including repairs and maintenance to essential service infrastructure, fuel management, municipal services and capital works projects. KRSP’s services are for the improvement and sustainability of the lives of Indigenous peoples from the Kimberley Region of Western Australia.
We have the resources and infrastructure to provide state-of-the-art services and a commitment to promoting opportunities for Aboriginal participation at all levels in our business. Since our inception in 1998, we have successfully provided services to remote communities throughout the Kimberley under various contracts to the state and federal governments. We are currently contracted to the Department of Communities – Housing Authority under the Remote Essential and Municipal Services Programme.
46% of KRSP’s workforce is indigenous, both in communities and in our head office in Broome. The continual focus on those employment outcomes, providing community members with rewarding jobs within their own communities, is a key factor in the continued success of KRSP as a joint venture. KRSP has gained a reputation for technical innovation, reliability, quality of workmanship and professional service.
