Severe flooding in New South Wales, Australia
In May 2025, three days of extreme rainfall prompted major flooding in the Hunter and Mid North Coast regions of New South Wales, Australia’s most populous state. The state’s emergency services agency estimated that the flooding impacted at least 10,000 properties and led to at least five casualties. The flooding further isolated around 50,000 people, with 52 flood rescues carried out in one night.
