The Mary River catchment is the southern-most of the Great Barrier Reef (GBR). The catchment is also a priority for sediment discharge into the southern GBR due to the high sediment delivery ratio. Grazing land constitutes approximately 70% of the land-use in the catchment. Consequently engaging with the grazing sector is extremely important to address downstream water quality improvements. Since the inception of the initial Reef Plan in 2005 the Mary River Catchment Coordinating Committee (MRCCC) has been working in partnership with the grazing sector to address these concerns. At this time the MRCCC developed a working partnership with the local grazing group, the Gympie District Beef Liaison Group which prospers today. Since 2015 the MRCCC has been working with the grazing sector in priority catchments of the Mary River catchment to address gully erosion concerns with an Australian Government Reef Trust funded project. This gully erosion project has predominantly targeted early intervention of gullies in known hot-spot catchments, working in partnership with technical advisors provided by Reef Trust. Using CSIRO Atlas of Australian Soils Landscape unit information from the 1960's priority landscape units are identified, providing direction for engagement activities. Within these priority landscape units preemptive actions on drainage lines predicted to gully, or showing early signs of gullying are targeted for low-cost activities such as fencing. The MRCCC has produced a number of extension 'tools' used in these projects for awareness raising and capacity building of participating landholders. These user friendly tools provide landholders with succinct information to make informed decisions on management actions required to address grazing land condition, gully condition and riparian zone condition. A monitoring program developed in partnership with Reef Trust has been established to objectively measure changes to the treatment gullies.
