Griggs Haulage Contractors are the sole contractor for the transport and application of Liquid Biodunder in the Burdekin Region.We operate a large fleet of B-Double Tankers to transport the liquid fertilizer from the Mackay Region up to the Burdekin Cane Farms where our applicators use a liquid one shot system to inject a stream of fertilizer directly over the stool to minimise the impacts of run off and to stay in line with Reef Rescue Regulations.
