Smoke alarm laws differ by state and are tightening, most now require photoelectric, interconnected alarms in every bedroom, hallway and level. Rental and sale compliance rules are stricter again.
Ways to save
- In an older home, wireless-interconnected lithium alarms avoid costly new wiring while still meeting the rules.
- Do all alarms in one visit, the electrician's call-out fee is a fixed cost spread across the job.
- Check your state's exact requirement before buying, fitting the wrong type means doing it twice.
How we estimate this
Installing smoke alarms in Australia typically costs around $150 to $250 per hardwired, interconnected alarm installed in 2026 when replacing existing units, so a typical home of four alarms often lands around $600 to $1,200. New wiring runs add more.

What a smoke alarm installation costs in Brisbane
A smoke alarm install in Brisbane is priced by how many alarms the home needs and whether they are hardwired and interconnected, and Queensland has the strictest smoke alarm law in the country, requiring interconnected photoelectric alarms in every bedroom, in hallways linking bedrooms, and on each storey. That raises the alarm count well above other states, so a Brisbane home typically needs more alarms than the same house would elsewhere, which is the dominant cost driver.
A licensed electrician fits the hardwired, interconnected photoelectric alarms the law demands, because hardwiring ties each to the mains with a battery backup and interconnection links them so every alarm sounds at once. The high count in a Queenslander with several bedrooms means more units and more interconnect wiring than a southern home, and threading link wire through an older Queenslander's ceilings adds labour, so wireless-interconnected alarms are often used to avoid it. The subtropical humidity and dust make photoelectric alarms, which the law mandates, more reliable than old ionisation types. Service labour near the national baseline keeps the per-unit install a touch below the southern capitals, though the higher alarm count lifts the total.
Hardwiring and interconnecting smoke alarms is licensed electrical work that must be done by a licensed electrician in Queensland, with licensing under the state regulator, and the install must meet Queensland's smoke alarm legislation. For a Brisbane home, the clearest way to price a smoke alarm install is by the number of alarms, which the state's strict interconnected-photoelectric-in-every-bedroom law pushes higher than elsewhere.
