The short answer
By 1 January 2027, existing private houses, townhouses, units and manufactured homes in Queensland must have interconnected photoelectric smoke alarms meeting the applicable requirements. Rental properties and homes being sold already have earlier obligations: 2027 is not an extension for them.

Does the deadline apply to your property?
For a Townsville owner-occupier, the first step is to check the existing installation rather than assume every alarm needs replacing. Some homes already meet the requirements; others need additional alarms, interconnection or replacement units.
Queensland rental dwellings already require interconnected photoelectric alarms. For property sales, contracts signed after 31 December 2021 trigger the seller’s obligation to upgrade before transfer. New homes and relevant major renovations have their own existing requirements. If you are renting, selling or renovating, do not wait for 2027.

What type of alarms and locations are required?
QFD specifies photoelectric alarms complying with AS 3786–2014, without an ionisation sensor, interconnected so that when one activates the others sound. Interconnection can be wired or wireless.
The required coverage includes each bedroom, connecting hallways or the area between bedrooms and the rest of the dwelling, and every storey. A level without bedrooms still needs appropriate coverage along the likely exit route. Exact positions depend on the layout; a generic room count is not an installation design.

Do you need hardwired or battery-powered alarms?
Wireless interconnection and battery power are different things. A hardwired alarm can communicate wirelessly with another alarm. QFD says an existing hardwired alarm must remain hardwired when replaced; 240-volt connections require a licensed electrician. Suitable non-removable 10-year battery alarms may be an option where the dwelling’s requirements allow them.
Ask about compatibility before buying individual alarms. Choosing a matching system and checking the existing power arrangements can prevent purchases that do not suit the property. Do not disconnect or alter wiring yourself.

What should you prepare before booking?
A little information helps turn a general enquiry into a useful conversation. You can send a simple floor plan and photographs taken from a safe position; there is no need to climb into a ceiling space or remove an alarm to expose its wiring.
- Tell us whether the home is owner-occupied, rented, being sold or under renovation.
- List bedrooms and levels, including any converted rooms or extensions.
- Note existing alarm locations and any model or manufacture information safely visible.
- Mention chirping, failed tests or alarms that do not sound together.
- Share your access arrangements and any sale, tenancy or renovation dates.
Does an upgrade replace regular maintenance?
No. Continue testing and cleaning to the manufacturer’s instructions. QFD advises replacing alarms that are over 10 years old or fail a test. Do not disable an alarm to stop unwanted activation.
Rental responsibilities also continue: owners or managers must test within 30 days before a tenancy begins or is renewed. During a tenancy, tenants must test and clean at least annually and report problems. An upgrade and day-to-day maintenance are separate jobs.
