North Stradbroke Island is a large sand mass of ecological and economic value and is a unique geological and hydrological feature. The island has evolved through a variety of marine- and wind-driven processes involving movement and deposition of sands. These processes have resulted in characteristic geomorphology and physical properties. An essential part of the development and function of the island is the regional groundwater body and in particular its relation to environmentally significant wetlands and lakes. Many of these surface features are perched above the regional watertable, but others can be connected. Here we utilise 3D visualisation of the island morphology to display these features. We use a scheme where surface water bodies or features, are categorised as Type A (high elevation discharge features), Type B (low elevation discharge features) and Type C (coastal seepage discharge features) and discuss the relationship to the groundwater system.
