MusicNSW is an important voice in the NSW music scene, and their website has info regarding grant applications, a huge directory of important music people in Sydney & the surrounds, and legal info so you don’t find yourself in a dispute over royalties or copyright disputes.
Information + Cultural Exchange is a Parramatta-based organisation that works with the community to create developmental pathways and opportunities through several workshops and programs that happen year round. (New Age Noise started as an ICE program!) They are dedicated to giving opportunities to people from vulnerable and disenfranchised communities.
APRA AMCOS is arguably the most important resource for musicians in Australia. They distribute royalties to musicians, and it’s incredibly easy to sign up and get paid. Sign up, put your track details, and if you get played anywhere on the radio, in ads, over the speaker at a retail store they’ll put money into your account.
