There are government grants for startup small business needs in Australia provided at the national tier. There may be more at the state or local tiers as well depending on your area. Without fail, know what you need the funding for and how much you need before starting your search, as then you can use the intended uses of the programs to compare with your needs and help narrow down your options. Pay attention to the eligibility terms too, as they differ from program to program.
You can also take advantage of the Small Business Startup Assessment Tool below and see the tools and resources you need to succeed at launching your business. It takes just a minute and will also tell you if there may be any funding programs available.
