TL;DR: Bunnings and Kmart stock generic security hardware - motion sensors, entry chimes, cameras and sensor lights - but not a dedicated motion-triggered barking-dog alarm. Those detect and announce; a barking-dog alarm deters with a realistic dog sound. Buy the barking type from a specialist Australian seller with a warranty and local support.
Can you buy a dog barking alarm at Bunnings?
Not directly. Bunnings stocks plenty of home-security hardware, but its range is detection and recording, not a barking deterrent. Its security and safety category lists PIR motion sensors, wireless doorway and entry chime alarms, plug-in alarm-system components and security cameras - useful devices, but none that plays a realistic dog bark.
The distinction matters. A doorway chime or motion sensor tells you someone is there, usually with a beep or a notification. A barking-dog alarm is aimed at the person outside, using a sound that signals an occupied home before they reach the door. Both have a place, but they are not the same purchase, and swapping one for the other leaves a gap.
That gap is worth closing because approach is where deterrence works. In 2024-25 the ABS recorded 196,600 households (1.8%) experiencing a break-in and 217,500 (2.0%) an attempted break-in (ABS, Crime Victimisation 2024-25). A chime that sounds after entry does little for the attempts; a deterrent that reacts at the approach does more.
What about Kmart, Big W or online marketplaces?
Kmart is similar but tilted toward cameras. Its home safety and security range centres on smart indoor cameras, Wi-Fi doorbell cameras, motion-sensor lights and smoke alarms - handy and cheap, but again not a dedicated barking-dog alarm. Big W and similar general retailers follow the same pattern: personal alarms, sensor lights and the odd camera, rather than a deterrent sound unit.
Online marketplaces are where "fake dog" and "barking alarm" listings do appear, imported and inexpensive. The catch is variable quality and support. Many are the looping-novelty type that repeats one bark on a timer, which is the easiest kind to recognise as fake, and a marketplace listing rarely comes with an Australian warranty or anyone to call. If you do buy online, check the return policy, look for a real motion sensor rather than a timer, and read the critical reviews rather than the star average. Our fake dog barking devices review covers how to spot the weak ones.
Generic alarm vs dedicated barking-dog alarm
The quickest way to decide is to match the device to the job. Here is how the common in-store options compare with a dedicated barking-dog alarm on the things that matter for deterrence.
| Device | What it does | Sound | Deters at approach? |
|---|---|---|---|
| Entry / doorway chime | Alerts you when a door opens or someone passes | Beep or chime | Limited - mainly notifies |
| PIR motion sensor | Sends an alert or app notification on movement | Optional siren or silent | Only if paired with a siren |
| Security camera | Records footage for evidence | None or two-way audio | Weak - records, does not deter |
| Dedicated barking-dog alarm | Plays a realistic bark when motion is detected | Large-dog bark, adjustable | Yes - occupied-home cue on approach |
The reason the barking type earns its place is the deterrent it copies. Australian Institute of Criminology interviews with active burglars found a dog was named as a deterrent by 61.4% of them, ahead of working alarm systems at 49.1% (AIC, Understanding Residential Burglary). A camera or chime does not reproduce that cue; a realistic, motion-triggered bark does.
What is worth buying in-store to go with it
A trip to the hardware or department store is not wasted - several cheap items genuinely strengthen a barking-dog alarm. They are not the deterrent itself, but they are the supporting layers that make it work harder, and both Bunnings and Kmart stock them well.
- Sensor lights - a motion light on a dark approach removes the cover an intruder wants, and pairs naturally with a sound that reacts at the same point.
- Better locks and deadbolts - the physical layer a sound can never replace. If a door or window is easy to force, harden it first.
- Timer switches - cheap plug-in timers cycle lights while you are out, adding the occupied-home cue the barking alarm reinforces.
- A doorway chime - useful inside for your own awareness of comings and goings, as long as you treat it as an alert, not a deterrent.
Layered simply, that is a strong, low-cost setup: hardened entries, light on the approach, an occupied look, and a reactive bark at the door. Our secure your home for under $200 guide sequences these in priority order so you spend on the highest-impact steps first.
Where to buy a barking dog alarm in Australia
Buy a dedicated barking-dog alarm from a specialist Australian retailer rather than a big-box store or an anonymous marketplace seller. The difference is not just the device - it is the warranty, the returns window and having someone local to help if a sensor needs pairing. A specialist seller also tends to stock the motion-triggered type by default, rather than the looping novelty units that dominate cheap listings. Before you buy, from any source, check the same short list.
Check before you buy
- Motion-triggered, not looping - the bark should start on approach, so it reads as a reaction.
- Realistic, adjustable bark - a believable large-dog sound you can set for your door and neighbours.
- Separate wireless sensor and a remote - to cover the approach and arm or disarm it easily.
- No Wi-Fi or subscription needed - so it works in sheds, rentals and blackouts.
- Australian warranty and returns - a local business beats a marketplace listing with no support.

Does Bunnings sell dog barking alarms?
Bunnings stocks generic home-security hardware - PIR motion sensors, doorway and entry chime alarms, alarm-system components and cameras - but not a dedicated motion-triggered barking-dog alarm. Those play a beep or chime, not a realistic dog bark, so they detect and announce rather than deter with an occupied-home sound.
Can you buy a barking dog alarm at Kmart?
Kmart's security range centres on smart cameras, Wi-Fi doorbell cameras, motion-sensor lights and smoke alarms rather than deterrent sound devices. It is a good place for a cheap camera or sensor light, but not for a dedicated barking-dog alarm.
Where is the best place to buy a barking dog alarm in Australia?
A dedicated barking-dog alarm is usually bought from a specialist retailer that sells the motion-triggered type, rather than a big-box store. Buy from an Australian seller that offers a warranty, a returns window and local support, so you are not relying on a marketplace listing with none.
Are cheap barking dog alarms from online marketplaces any good?
Some are fine, but marketplace listings are often the looping-novelty type that repeats one bark on a timer, with variable quality and no local support. The trigger is what matters: a unit that barks only when its sensor detects approach is more convincing than one that loops regardless.
