Re: need advice from aussie drummers!
For what it's worth, I'll give you my (slightly biased) opinion...
I've been to Sydney (it's alright :P), I live in Melbourne. My understanding is that the majority of the record labels are in Sydney, while the majority of the live music scene is in Melbourne.
That being said, I chatted to a bass player the other day who told me theres a thriving Jazz Scene in Perth.
I don't know anything at all about Brisbane, but my bro lived there for 6 months, and he reckoned it was fairly quiet.
My opinion. Shoot for Melbourne, but if you're willing to work hard, you can survive anywhere. (bigger is better, if Melbourne's not an option, I'd say Sydney)
On the other hand... Savage Garden came from Brisbane... Ooh.
(i realize you said Sydney or Brisbane, I added Melbourne in myself)
