Digital Rain Dance
while much of the country is still burning there isn't much that normal people can do, apart from donating to your local fire service, or volunteer to help out (don't be out-manned by Tony Abbott!)
TAS I can't find a dedicated page so please contact your local TFS branch
WA No dedicated page but many small groups take donations and I'm not going to fact check them all, contact your local Fire Service branch
In the meantime, and it seems a bit hippytrippy I'll admit, I've joined in the #digitalraindance movement. #prayforrain The rational part of my brain acknowledges that VIC and SA both have long, dry summers and rain isn't forecast until March.... but hey, hoping, wishing and praying can't hurt.
