Australia is now describing it as its costliest natural disaster ever.
The government estimates that floods that have devastated parts of the country will end up costing the equivalent of 7.5 billion euros.
Authorities have announced a judicial inquiry ino the tragedy.
Queensland State Premier Anna Bligh said: “We need to know where mistakes might have been made and if there are big lessons here. We need to learn them as quickly as possible because one thing we know for absolute certain: there will be other major weather events causing flooding in Brisbane, in Queensland and in our regions.”
Flooding has hit four Australian states since December and the current death toll of 30 is expected to continue rising.
The southern state of Victoria is bracing for what officials are warning could be a “one in 200-year flood.”
This after suffering from drought for much of the past 13 years.
