Campsites represent a form of low-impact, minimally invasive ecotourism infrastructure that has grown in popularity alongside the development of national parks globally. Australia, an island nation with a long history of establishing marine national parks, boasts well-developed ecotourism facilities, including sophisticated camping site planning and management systems. This study focuses on the planning and management of camping sites within marine national parks on Australia's west coast, examining three distinct case studies. It identifies the key features of planning and management across different types of camping sites in Australian marine national parks and analyzes the various factors influencing their planning and management. The research highlights how the selection and planning of sites in marine national parks are predominantly affected by the need to balance the recreational use of marine resources with marine ecological conservation objectives. It posits that effective camping site planning and management are crucial for reconciling the dual goals of marine ecology protection and the enhancement of marine recreational opportunities within marine national parks. The study proposes a comprehensive framework for the construction and management of camping sites in marine national parks, ranging from site selection to layout management. This framework aims to serve as a guide and inspiration for the planning and management of marine-based national park campsites in China.
