Dryland social-ecological systems in Australia are characterized by a water-limited climate, vulnerable terrestrial ecosystems, advanced ecosystem management, and the highest average wealth. Dryland social-ecological systems in Australia have been facing the accelerated warming and rapid socioeconomic developments since the twenty-first century, including GDP increases and urban development, but with great diversity. Ecosystem structures and ecosystem services are highly influenced by extreme climate events. According to the number of extreme high daily precipitation events, droughts and floods have increased rapidly since the 1970s. Australia has achieved successful grazing, fire, biodiversity, and water resource management; climate change mitigation; and ecosystem manage-ment methods of community engagement. Non-indigenous population ageing is a social threat of dryland social-ecological systems in Australia in recent decades. The integration of policy makers, funding agencies, and the general public is essential for Australia’s dryland social-ecological systems.
