How it works in South Australia
South Australia requires at least one working smoke alarm meeting AS 3786 on every storey, positioned outside sleeping areas. Landlords must keep alarms in working order, and any alarm that is replaced must be either mains-powered or fitted with a 10-year sealed battery. SA does not impose a fixed annual rental-specific test like Queensland, relying instead on the ongoing duty to keep alarms functional, alongside minimum housing standards that apply to rentals from 1 July 2024.
