Hundreds of thousands of people in Australia's Queensland state were without power on Sunday after Alfred, a downgraded tropical cyclone, brought damaging winds and heavy rains, sparking flood warnings.

Significant damage and power outages are possible in the densely populated region of Queensland, where tropical cyclones impacts are not uncommon but direct landfalls are.

Cyclone Alfred - which has been downgraded from a cyclone to a tropical low - has caused flooding, damage to buildings and left thousands without power across the eastern coast of Australia. Millions of people across Queensland and north New South Wales have been affected.

The Australian prime minister has warned there is "worse to come" after a low tropical weather system brought heavy rain, strong winds and flooding to the country's east coast. Anthony Albanese said the impacts of ex-Tropical Cyclone Alfred are already being felt across parts of Queensland and New South Wales,
