Ex-tropical cyclone Alfred lingered off the south-east Australian coast on Saturday and forecasters said Brisbane is likely to miss the worst of the storm, a relief for millions of residents in the region who have been staying indoors.

One man died in floodwaters, the authorities said, and over 330,000 customers were without power in South East Queensland.

Ex-Tropical Cyclone Alfred continues to unleash destructive weather across South East Queensland and northern New South Wales, with forecasters warning of flood risks and severe conditions persisting over the coming days.

Cyclone Alfred weakened into a tropical low Saturday as it neared the rain- and wind-lashed eastern coast of Australia where hundreds of thousands of properties were without power. The former tropical cyclone lay about 65 kilometers off the coast of the Queensland capital, Brisbane, government forecasters said in a final update.

Gusts and torrential rain have blacked out more than 300,000 properties and swamped parts of Australia's east coast, officials said Sunday, with one driver confirmed dead and a dozen troops

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.

A slow-moving tropical storm crossed islands off Australia’s heavily populated eastern coast late Friday, lashing coastal suburbs with destructive winds and dumping heavy rain across the region.

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.

Ex-tropical cyclone Alfred has officially reached the mainland in Queensland's south-east bringing with it intense winds and fears of flooding.
