Rapid creek rises and dangerous flash-flooding is impacting parts of South East Queensland and Northern New South Wales.

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.

Ice Cube has found himself caught in the chaos of Cyclone Alfred, with the rap icon stranded at his Gold Coast hotel as the storm barrels toward Australia’s southeastern coast.

Tropical Cyclone Alfred is forecast to cross the coast between the Queensland state capital Brisbane and the tourist city of Gold Coast to the south late Thursday or early Friday.

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,
