Floodwater rose across a vast area in Australia’s northeast on Friday, inundating 22 towns, forcing 200,000 residents out of their homes, and closing a major sugar export port.
Flooding has already shut coal mines in Queensland state and its biggest coal export port, forcing miners such as Anglo American and Rio Tinto to slow or halt operations.
The worst flooding in about 50 years has been caused by a “La Nina” weather pattern, which cools waters in the eastern Pacific and has produced torrential rain over the past two weeks across northeast Australia.
In the southern states of Victoria and South Australia, meanwhile, soaring temperatures and tinder dry conditions have sparked bushfires.
Authorities warned of possible “catastrophic” fires if conditions worsened and holiday travelers were asked to prepare evacuation plans.
“We’re asking people to have a plan, how they’re going to get to where they’re going…a plan to get away…if a bushfire happens to threaten,” said South Australia rural fire chief Andrew Lawson.
Firefighters, helped by cooler temperatures, contained small fires late on Friday, but meteorologists said readings could soar again above 40 degrees Celsius (104 degrees Fahrenheit) in the next few days.
In Queensland, authorities warned of rising health risks from floodwaters, along with the danger of crocodiles and snakes in flooded homes.
“This disaster is a long way from over,” Queensland state Premier Anna Bligh told reporters.
“We now have 22 towns or cities that are either substantially flooded or isolated. That represents some 200,000 people spanning an area that’s bigger than the size of France and Germany combined.”
Prime Minister Julia Gillard toured the sugar city of Bundaberg, which closed its port on Friday after flood debris was washed downstream into shipping channels and damaged navigation beacons.
“This is a natural disaster across Queensland,” Gillard said, announcing a A$1 million ($1 million) government contribution to a flood aid appeal which now totals A$6 million.
The closure of Bundaberg has disrupted shipments of sugar from Australia, a leading world exporter. The port normally ships about 400,000 tonnes of raw sugar annually, with three 30,000-tonne vessels due to arrive in the next few days.
“If the port is closed for only a few days it won’t be a big issue but any extended delay would cause some concern,” said Brian Mahoney, an executive with Marybrough Sugar Factory Ltd.
