The principal smoke alarm laws in Western Australia consist of;

– the W.A Building Regulations 2012 (division 3) and;

– the Building Code of Australia.

In 1997 hard wired 240v smoke alarms became compulsory in Western Australia for all newly constructed residential buildings (or residential building extensions). From 2009 onwards this was extended to also include all existing residential buildings, prior to their transfer of ownership, rent or hire.

In W.A smoke alarms must;

  • be positioned according to the requirements of the Building Code of Australia
  • comply with Australian Standard 3786:2014
  • be permanently connected to consumer mains power
  • be interconnected, if your home was newly built after the 1 May 2015.
  • be less than 10 years from the date of manufacture

The W.A Building Regulations 2012 does allow the use of non-replaceable lithium battery powered smoke alarms in certain situations however. This may include where mains power is not connected to the building, there is no hidden space to run the necessary wiring for mains powered alarms, and there is no appropriate alternative location – for example, where there is a concrete ceiling. Formal approval must be obtained by the local council to use lithium battery powered alarms in these situations.

Landlords who rent or hire out their property to tenants are required by law to maintain the smoke alarms. This includes ensuring the smoke alarm is;

  • in good working order;
  • permanently connected to mains power (i.e. 240 volt hard wired);
  • less than 10 years old from manufacture date;
  • if the use of a battery powered smoke alarm has been approved by the local council, the alarm has a non-removeable 10-year life lithium battery (i.e. not a 9 volt replaceable battery).

According to W.A legislation both ionisation and photoelectric smoke alarms are permissible, however the W.A Department of Fire and Emergency Services (DFES) recommend interconnected photoelectric smoke alarms as the preferred type.

Just like most other Australian states and Territories, South Australia also requires working smoke alarms to be fitted into every property. Fines up to $750 can be imposed if smoke alarms are not installed, and for rental properties the onus is on landlords to ensure the smoke alarms are working.

The two main pieces of legislation for smoke alarms in South Australia are;

Regulation 76B of the Development Regulations 2008 and Regulation 95 of the Planning and Development Infrastructure (General) Regulations 2017 specify requirements for smoke alarms in dwellings.

In summary, they mention that;

Existing homes or residential properties built prior to 1 January 1995

A replaceable battery powered smoke alarm may be installed in these premises subject to any future change of ownership conditions.

When an existing house built prior to 1995 is sold, then the owner has 6 months from the date of title transfer to install smoke alarms which are either 240 volt mains powered or have a 10 year life non-removeable lithium battery.

Regulation 76B of the Development Regulations 2008 does not require multiple smoke alarms to be interconnected, unless required by the Building Code of Australia for new additions or extensions to existing dwellings – see also here for guidance.

New houses or residential properties built after 1 January 1995

The Building Code of Australia requires a 240 volt, mains powered smoke alarm that is interconnected.

Further advise on the interconnection of smoke alarms in South Australia is available here.

Legislation in South Australia does not specifically stipulate between ionisation or photoelectric smoke alarms, although the South Australian Metropolitan Fire Service state that interconnected photoelectric smoke alarms provide the best protection across a range of fires.

The governing piece of smoke alarm legislation in the Northern Territory is called the Northern Territory Fire and Emergency Regulations 1996 (as in force 1 October 2019).

Part 2A of this regulation details requirements relating to smoke alarms, notably to do with the type of alarm, installation, maintenance and testing. A summary is provided below;

All owners of residential property must have working smoke alarms installed and tested annually.
Any existing ionization alarms must be replaced with the photoelectric type when they no longer work, the property is sold, or premises are rented out or a lease is renewed.
The responsibility for testing the alarm in a tenanted property lies with the tenant. The tenant must advise the owner or agent if the alarm does not work.
Section 13A (3) of the regulation states that an approved smoke alarm means a photoelectric type that:

(a) complies with Australian Standard 3786 and;

(b) is hard wired or is a sealed 10 year lithium battery unit.

A copy of the Northern Territory Fire and Emergency Regulations 1996 is available for download at the link below if you would like to read it.

Smoke alarm rules and regulations in Victoria are derived primarily from the Victorian Building Regulations 2018 (which requires smoke alarms to be installed in accordance with the Building Code of Australia). Amendments are also being made to the Victorian Residential Tenancies Act which will place extra duties on the landlord.

240v mains powered hard-wired smoke alarms with a battery back-up must be installed in all Victorian buildings constructed after 1 August 1997, like these Red brand 240 volt lithium battery back-up smoke alarms.

Buildings constructed before 1st August 1997 can have a battery-powered smoke alarm, like these wireless interconnected photoelectric smoke alarms with a 10 year long life lithium battery.

As a legal minimum the state requires at least one smoke alarm on each floor of a dwelling, positioned to detect to smoke before it reaches the sleeping occupants of a building.

The Victorian Country Fire Authority (CFA) recommend smoke alarm best practice above and beyond minimum legal Victorian requirements – refer to the direct link below.

On 1 May 2006, the NSW Government introduced new legislation following a series of fatal house fires. Division 7A of the ‘Environmental Planning and Assessment Regulation 2000’ calls out the minimum requirements for smoke alarm installation in existing buildings and says that;

– Smoke alarms must comply to Australian Standard 3786:2014 and can be either battery operated or hard wired to mains power.

– A minimum of one working smoke alarm should be installed on each level of a dwelling (even if there are no bedrooms on that level).

Note that whilst this is the minimum required by NSW law, Fire and Rescue NSW recommends installing smoke alarms in all bedrooms and living spaces (including hallways and stairways).

A new section (64A) relating to smoke alarms has also been added to the NSW Residential Tenancies Act 2010. This new section came into effect on March 2020 and placed extra obligations for smoke alarms on landlords in accordance with the Rental Tenancies Regulation 2019. It states that landlords must replace a smoke alarm within 10 years of manufacture and ensure the smoke alarm is tested at least annually.

Fire and Rescue NSW recommend smoke alarm best practice above and beyond minimum legal NSW requirements – refer to the direct link below.

These new laws were introduced in Queensland due to several house fires which resulted in multiple fatalities.

Had the dwellings in each instance been fitted with functioning wireless interconnected photoelectric smoke alarms the victims may have stood a chance of surviving.

Early detection = early alarm = early escape from a burning building. When the fire occurred, it was not only the flames themselves which presented as a hazard – most victims were first overcome by breathing in fumes and thick smoke.

Palace Backpackers Fire – Childers

In June 2000 a resident of the Childers Palace Backpackers Hostel maliciously lit a fire inside. The fire quickly spread throughout the timber building. Unfortunately the hostel did not have working smoke detectors or alarms and fifteen young people died as a result. The after effects of this tragic event are still evident on the local township to this day.

The arsonist was captured by police and sentenced to life imprisonment.

Slacks Creek House Fire – Brisbane

A few minutes before midnight on 23rd August 2011, a  fire tore through a house in the suburb of Slacks Creek, South Brisbane.

This fire caused the greatest loss of life in a domestic house fire in Australian history, with eleven people (including many children) dying due to inhaling toxic smoke.

A finding from the 2014 Coronial Inquest stated that;
‘Once this particular fire started, it is likely that some or all of the deaths would have been prevented if the sleeping occupants had been quickly awoken and had realised that they needed to leave the house as quickly as possible … smoke alarms were either not present in the dwelling or were not maintained’.

Many prescriptive requirements and recommendations from the Coronial Inquest were subsequently incorporated into the QLD Building Fire Safety (Domestic Smoke Alarms) Legislation Amendment Regulation 2016.

The legislation can be read here;

The two key pieces of legislation in QLD are called the Fire and Emergency Services Act 1990 and the Building Fire Safety Regulation 2008.

The goals of the legislation are to ensure that all fire safety installations (including smoke alarms) within a building are maintained.

Part 5A of the Building Fire Safety Regulation deals with interconnected smoke alarm requirements for domestic dwellings and says smoke alarms must;

  • Comply with the Australian Standard AS 3786:2014
  • Contain a photoelectric sensor, and not also contain an ionization sensor
  • Be hardwired into a building’s power supply or powered by a non-removable minimum 10-year lifespan battery

The QLD Fire and Emergency Services Act says that from 1st January 2022 all rental properties in QLD must have smoke alarms which;

  • Are less than 10 years old
  • Be interconnected with every other smoke alarm in the building so that all activate together
  • Operate when function tested

Additionally, these requirements will become mandatory for ALL dwellings in Queensland by 1st January 2027.

There are three important differences between our wireless interconnected photoelectric smoke alarms and conventional smoke alarms.

1) Our smoke alarms are photoelectric (not ionisation). Older conventional smoke alarms use radioactive ionisation as the process by which they detect smoke particles in the air. Ionisation smoke alarms are good at detecting smoke from flaming fires, but are less adept at detecting smoke from smouldering flames which is common of most house fires. Ionisation alarms have also been known to cause frustrating nuisance alarms, which might condition people to switch them off, putting themselves at risk. For these reasons the older style ionisation smoke alarms are being phased out both in Australia and internationally.

2) Older smoke alarms typically operated as stand-alone units. If a smoke alarm sensed smoke on the ground floor of a building – yes it may activate, but any other smoke alarms on the upper floors would not activate until smoke had entered the same air space – by this time it could be too late to initiate an effective response (or escape).
Our smoke alarms are wirelessly ‘interconnected’ together – so if one alarm detects smoke anywhere within a building, then all smoke alarms paired within the same network will simultaneously initiate their alarm. This can provide increased early warning and response time for residents.

3) Our smoke alarms have a sealed 10 year life lithium battery. Conventional smoke alarms are usually powered by a 9v replaceable battery. When the battery life becomes drained over time the smoke alarm begins to emit a loud intermittent ‘chirp’ noise. The chirp serves as a noisy (and annoying) reminder to replace the battery, and continues until the battery is replaced. As seen in the past, residents can remove the battery, disabling the chirping noise and the alarm itself, often with tragic consequences.
Because our smoke alarms are powered by a long life 10-year lithium  battery which is sealed inside the unit, the battery cannot be deliberately removed. At the end of the 10-year battery life span, the entire smoke alarm unit is simply replaced with a new one!
Don’t risk your life or that of your loved ones – whatever smoke alarm you have in your home please check to ensure it is; interconnectable, photoelectric and contains a sealed 10 year long life battery (or hard wired).

On 1st January 2022 new laws outlined in the Queensland Fire and Emergency Services Act 1990 came into effect. These new laws place extra duties upon Queensland property sellers to ensure that;

– interconnected photoelectric smoke alarms have been installed on every level and in every bedroom and interconnecting hallways outside the bedrooms

– be powered by either hardwired 240-volt or 10-year lithium batteries

– comply with Australian Standard 3786:2014 and be less than 10 years old

Disclosure obligations and smoke alarm compliance

If you are selling a residential property in QLD you are required by law to disclose certain information to the buyer before they enter into a contract – the two main documents where this information is captured are;

  • the contract of sale
  • the ‘Form 24’ (Transfer of Title)

Contract of Sale

The standard contract of sale in Queensland contains a section that the seller is required to complete prior to the buyer signing the contract, stating whether the property is fitted with compliant smoke alarms. When preparing a property for sale, these smoke alarm requirements must be met before a property can settle.

As a seller you cannot contract out of this obligation and must comply with the minimum smoke alarm requirements. Failure to install compliant smoke alarms is an offence (even if it has been disclosed) and the seller may be subject to a fine (a seller can still be fined for committing an offence after the property has been sold). As such, it is recommended that QLD sellers ensure compliant interconnected photoelectric smoke alarms are installed at their cost prior to settlement.

Form 24

When a property is sold, the vendor must also lodge a Form 24 (Transfer of Title) with the Queensland Land Registry Office, stating that the above requirements of the smoke alarm legislation have been met, and that the purchaser is aware of the fact. The Queensland Fire and Emergency Services (QFES) can subsequently access the property specific smoke alarm information contained within the Form 24.
