The region is mostly rural, with Beaudesert and Boonah the main towns. It lies within the catchment areas of the Bremer River, the Logan River/Albert River and the Coomera River/Nerang River. The centre of the area is dominated by the Flinders Peak Group and broad sweep of mountainous terrain forming a southern boundary with the local government area on Queensland's southern border with New South Wales. Many high-altitude areas are covered by forests and protected in national parks (including World Heritage listings) at Tamborine Mountain, McPherson Range, Main Range National Park, Mount Barney National Park and landforms including Cunninghams Gap and Fassifern Valley. South East Queensland's highest mountain is Mount Barney, reaching above sea level. Wyaralong Dam is the region's newest reservoir.
