City of Sydney Cultural Grants and Sponsorships funding program is open twice a year, with the first round now open.
There is no specific limit on how much you can apply for, however grants are generally between $5,000 and $20,000. For-profit venues, event promoters, record stores, labels etc. can now apply for funding for any project that is designed predominately to benefit the community. Head here for more information on the grants and how to apply.
The council have also recently introduced a small grant for local venues wanting to undertake acoustic audits on their premises. Funding of up to $5,000 is available, but it needs to be matched with either cash or in-kind support from the applicant. The acoustic audit grant is available for application anytime throughout the year. Head here for more information.
