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 Melbourne
A smoke alarm install in Melbourne is priced on the count of alarms the home needs and whether they are hardwired and interconnected instead of standalone battery units, since the work is in running mains power and an interconnect link to each position. The alarm count follows the plan: one per storey and in or near the bedrooms, so a larger period home with several bedrooms needs more alarms than a compact flat, and interconnection makes every alarm sound together when one detects smoke.
A licensed electrician fits hardwired, interconnected photoelectric alarms as the standard, because hardwiring connects each alarm to the mains with a battery backup and interconnection links them so a fire at one end of the home wakes a sleeper at the other. Threading the interconnect wiring through the ceilings and lath-and-plaster of an older Victorian or Edwardian home adds labour where access is awkward, so wireless-interconnected alarms, dearer per unit, are often used to avoid chasing link wire. A battery-only alarm a homeowner can fit, but the hardwired and mains work is licensed. Competitive trade labour just below Sydney's keeps the install reasonable, and a cold-climate home sealed up in winter still needs alarms sited clear of heating.
Hardwiring and interconnecting smoke alarms is licensed electrical work that must be done by a licensed electrician in Victoria under the Victorian Building Authority, and the install must meet the Victorian smoke alarm requirements for placement and type. For a Melbourne home, the clearest way to price a smoke alarm install is by the number of alarms and whether they are hardwired and interconnected, with retrofit wiring through a period home's ceilings the main labour driver.
