Smoke alarm and safety compliance for rentals, state by state
Every Australian state and territory requires working smoke alarms in rental properties, but the detail varies a lot — whether alarms must be photoelectric, interconnected, or hard-wired, how often a landlord must test them, and what other safety checks (electrical safety switches, gas safety, pool fencing) apply. The summaries below cover the smoke alarm rules and the most important related safety obligations in each jurisdiction.

Common questions
Do landlords have to test smoke alarms in Australia?▾
Yes, in most states a landlord or their agent must test and maintain smoke alarms, typically at least every 12 months and before a new tenancy. Queensland and Victoria have the strictest regimes; some states rely on a general duty to keep alarms in working order rather than a fixed annual test.
What is a photoelectric smoke alarm and where is it required?▾
A photoelectric alarm detects smouldering smoke using a light sensor and is now the preferred or mandatory type. Queensland requires photoelectric alarms by law; other states require alarms that meet Australian Standard AS 3786 and generally recommend photoelectric over older ionisation models.
What other safety checks apply to rental properties?▾
Depending on the state, landlords may need electrical safety switches (RCDs), periodic gas and electrical safety checks, pool barrier compliance certificates, and minimum housing standards covering ventilation, locks, and heating. Victoria has the most extensive checks; Queensland and WA mandate safety switches.
