Infrastructure Projects

Railways
	Queensland Rail was the first to adopt the VS in Australia for large scale infrastructure protection. For the stabilisation of steep batters of a service road built along the steep section of the rail line between Murphy Creek and Toowoomba (32km), VS was used extensively with other conventional engineering methods, at a much lower cost. Vetiver was also used to stabilise batters along the new Brisbane Gold Coast line.
Queensland Water Resources
	VS was used extensively with other conventional engineering methods for soil erosion and sediment control on road batters and other earthworks associated with the construction of the Teemburra Dam project, north Queensland.

Flooded structure and streambank stabilisation
	The South Johnstone sugar mill near Innisfail built a water-cooling cascade on the bed of the South Johnstone River, which is often flooded during the wet season. VS was used very effectively to protect the sides of the cascade in the last 7 years with flood velocity often reached up to 3.5m/sec.

Queensland Main Roads
	Following the successful trial at Split Rock on the Lakeland-Laura road in Cape York Peninsula, where the soil is extremely erodible and unstable, VS is being used as the main method of stabilisation for steep road batters, culvert inlets and outlets and table drains protection on the Cooktown Lakeland road. Furthermore the Peninsula District of Queensland Main Roads has adopted VS as the main bio-engineering techniques for erosion and sediment control on the highly erodible soil and extreme climatic conditions of the region. When VS was used, the cost saving for this project was between 60-75% as compared to conventional structures. Vetiver was also used to stabilise the abutment of Sandy Creek Bridge on the new duplication of the Gatton bypass in south east Queensland.
