If anyone is interested in practical assistance, there is a Queensland Government Flood appeal where you can donate. ATM money is the main thing needed as people are going to need assistance with rebuilding their lives and homes. Over here home insurance rarely covers floods, particularly if you live in a known flood zone so some of these people will not be able to afford to rebuild or repair their homes on their own.
