Cyclone-ravaged Australia like 'a war zone'

Sydney : Towns remained cut off in northern Australia Wednesday after being pummelled by a powerful cyclone that washed battered yachts ashore and ripped roofs off houses in scenes compared to "a war zone".

The category four storm slammed into the coast of Queensland state between Bowen and Airlie Beach on Tuesday afternoon, packing destructive winds and devastating some of the region's tourist hotspots.

It has since been downgraded to a tropical low but the Bureau of Meteorology still warned of damaging wind gusts with "intense" rain, sparking flooding fears as river levels rise.

"This rainfall is likely to lead to major river flooding over a broad area this week," it said.

Some areas have been drenched in "a phenomenal" 1,000 millimetres (39 inches) of rain in just 48 hours -- the equivalent of half a year's worth, according to the weather bureau.

Roads to the towns of Bowen, Airlie Beach and Proserpine were inaccessible, with more than 60,000 homes without power and communications down in many areas. But no deaths were reported and only one significant injury -- a man crushed by a collapsing wall.

Queensland Premier Annastacia Palaszczuk flew by helicopter to Bowen, which bore much of the brunt, and said mass evacuations helped save lives.

Tens of thousands of people moved to higher ground or cyclone shelters or left the region before Cyclone Debbie made landfall.

"Thankfully the extent of the damage here is not as widespread as we first anticipated, but of course there are lots of trees down... we've seen the impact of roofs being blown off people's houses," she said.

The premier was due to head to the town of Proserpine where "we expect there to be some more widespread damage".

Dawn broke on scenes of devastation.

Pictures posted on social media showed a light plane flipped upside down, yachts washed ashore, power poles down and trees fallen on houses.

Whitsunday Regional Council mayor Andrew Willcox described cyclone-ravaged Bowen as "like a war zone".

"This beautiful seaside town is now half-wrecked, but we will rebuild," he told Channel Nine television.

In the mining town of Collinsville, residents said the storm was emotionally draining, with winds raging for hours as they cowered inside.
