The 19th National Congress of the Communist Party of China clearly stated that China will establish a natural protected land system with national parks as the core part. The national park system pilot reform has been carried out smoothly, but there is still a long way to go in terms of institutional mechanisms. This paper analyzes the characteristics of Australian national parks management in management system, financial guarantee mechanism, and key fields and came up with the suggestions on the national park management system in China, in order to provide references for China's national park system pilot. The analysis shows that the national park management model in Australia is diverse, which is generally composed of two categories:the joint management by the park bureau and the local stakeholders and the independent management by the park bureau. Three-level management structure of the director/director assistant-department-division is adopted. The fund guarantee mechanism is sound, and the funding mainly come from fund donations, financial appropriations and ticket income. The key fields to work are well identified, i.e., strengthening ecosystem resilience, promoting the participation of traditional owners in the management, and increasing the attractiveness of parks to tourists. Other points that are worthwhile to learn include high attention to resource monitoring, correct dealing with the relationship with local communities, a highlight to the innovational application of high-tech and social media, timely conclusion and reporting, and development plans development.
