Torrential rain in Australia's south-east has caused severe flash flooding, leading to evacuation orders and warnings for 50,000 residents in New South Wales to prepare for isolation. One death has been confirmed, and three people are missing. Over 100 schools are closed, and thousands are without power as the region experiences widespread destruction to farms, homes, roads, and bridges. Authorities are conducting numerous rescue operations, with more heavy rainfall expected before the system moves south.
