Queensland has some of the most stringent smoke alarm requirements in Australia — and for good reason. House fires kill more than 50 people every year in Queensland. The new legislation, phased in from 2017 and now fully applicable to all dwellings, significantly improves early warning capability and gives occupants more time to escape.
What Changed Under the New Laws?
Queensland's Building and Other Legislation Amendment Act 2017 introduced a requirement for photoelectric, interconnected smoke alarms. The key differences from older ionisation alarms:
- Photoelectric technology: Responds faster to smouldering fires (the most common house fire type), unlike older ionisation alarms which respond better to fast-flaming fires.
- Interconnected: When one alarm activates, all alarms in the home sound simultaneously. This is critical for occupants in bedrooms away from the fire source — especially at night.
- Hardwired or 10-year lithium battery: Alarms must be powered by mains power (hardwired) or a non-removable 10-year lithium battery. No more replaceable 9V batteries that get removed when they beep.
Compliance Deadlines — Is Your Home Due?
| Dwelling Type | Deadline | Status |
|---|---|---|
| New builds & major renovations | January 2017 | Mandatory since 2017 |
| Rental properties (leased/sold) | January 2022 | OVERDUE — must comply |
| All other existing dwellings | January 2027 | Deadline approaching |
Where Must Alarms Be Installed?
Under the new laws, interconnected photoelectric alarms must be installed:
- In every bedroom
- In hallways that connect bedrooms to the rest of the home (or if there's no hallway, between the bedrooms and other parts of the home)
- On every storey of the dwelling — even if there are no bedrooms on that level
For a typical 3-bedroom, single-storey home, this usually means 5–7 alarms interconnected throughout the property.
Hardwired vs. Battery-Powered Alarms
Both types are acceptable under Queensland law, but there are important differences:
- Hardwired alarms connect to your home's mains power and must be installed by a licensed electrician. They're the most reliable option and can be interconnected via the home's wiring.
- 10-year lithium battery alarms can be installed by a homeowner (in existing dwellings), but must use the specific 10-year sealed lithium battery — standard 9V batteries are not compliant. Wireless interconnection technology allows these to communicate without hardwiring.
We recommend hardwired interconnected alarms where practical — they eliminate battery maintenance concerns and provide the most reliable protection.
Consequences of Non-Compliance
- Insurance invalidation: Many insurers now require compliant smoke alarms as a policy condition. A non-compliant home may face rejected claims after a fire.
- Selling or renting: Landlords must provide a Smoke Alarm Compliance Declaration before renting. Non-compliant rental properties face fines.
- Property sale: Sellers must ensure compliance before settlement or a buyer can claim compensation.
