Australian Prime Minister Anthony Albanese on Sunday toured flood-hit parts of Victoria state, including the city of Melbourne, as three states continued to grapple with a flood crisis sparked by days of heavy rain.

Warnings were current for flood-impacted parts of Victoria, southern New South Wales and northern regions of Tasmania after a weather system dumped more than a month's worth of rain on the southeast.

The crisis comes after Australia's eastern states were hit by severe flooding in early 2022 as the country endures a third consecutive La Nina weather event, bringing heavy rains.
