If electronic music is your thing (as a metalhead I can definitely appreciate some electronic music from time to time), Resident Advisor has a big list of artists who are raising money to help.
The Amity Affliction* are from Australia, and donating money via their label and their own webstore:
We’ll be donating $1 from worldwide pre-orders thanks to @purenoiserecs and $5 from orders through our Australian Webstore @24HundredNet to the Australian Bushfire Appeals. Pre-order here: https://t.co/PUMOHOO8rz

I’m definitely missing a bunch of others, so if you know of anyone else donating money via their music, art, or anything else, please let me know!
