What do I need to start a small business in Australia?

Starting a small business in Australia requires completing several foundational legal and administrative steps before launching operations. You must first establish an appropriate business structure—such as operating as a sole trader, partnership, or company—and register for an Australian Business Number (ABN) to operate legally. Additionally, registering a business name, setting up Goods and Services Tax (GST) if your annual revenue reaches regulatory thresholds, and securing all relevant local permits, industry licences, and business insurance are essential to protect your venture and remain compliant.
