What insurance does a South Australian business need?
Most South Australian businesses hold public liability, a business pack for their premises and stock, tools cover if they work on site, and professional indemnity if they give advice. Which ones apply depends on what you do, your contracts, your lease and your licence.
The ABS counted 174,310 actively trading businesses in South Australia at 30 June 2026, up 3.3% in a year, and about two thirds of Australian businesses have no employees. Most of the requests for a certificate of currency described below come from that base of small operators.
The compulsory ones are workers compensation through ReturnToWorkSA once you employ, CTP with your vehicle registration, and building indemnity insurance on domestic building work of $20,000 or more that needs development approval.
