It’s easy to forget your smoke alarm’s there until it starts beeping or chirping. But while we take them for granted, they’re always keeping tabs on fire safety.

Our top pick Google Nest Protect is expensive, but all its extras make it worth the price. It offers remote notifications, a light, voice notifications, and more.

1. Google Nest Protect: Best smoke alarm overall

The Google Nest Protect keeps your home protected in more ways than one. Sure, it can detect smoke, but with its split-spectrum sensor, it detects smoldering fires as well as fires with active flames. It also detects carbon monoxide with an electrochemical sensor.

When a smoke or carbon monoxide detector is triggered, the Nest Protect will flash its built-in light, sound an alarm, and use voice alerts to let you know exactly what type of emergency it's detecting. It also sends alerts to your phone through the app.

Though we prefer the wired version, there is a battery-powered model if you don't mind changing the batteries from time to time.

The drawback is it's expensive for a fire alarm. Still, the benefits are worth the price, especially if you have a smaller home that doesn't need too many smoke detectors. If you're on a budget, it's better to opt for the next pick.

If you're looking for a bare-bones smoke detector that does what it says on the tin and nothing else, the budget-friendly Quell Photoelectric Smoke Alarm is for you.

It's good quality, affordable, and available from Woolies, so you can even pick one up during your weekly shop.

If you've got a larger home, you'll want to have more than just one smoke alarm. This three-pack from 24M offers a cost-effective solution for covering a few key areas.

It's got pretty basic features, much like our budget pick above, but we like that it's made of a fire-retardant material, meaning it should continue sounding in the event of a fire.

Pro Bullet Loud 85dB alarm
Pro Bullet Fire retardant material

In Queensland, all rental properties (and, by 2027, all dwellings) are legally required to have interconnected photoelectric smoke alarms. Even for non-Queenslanders, interconnected smoke alarms are the safest choice. This one from Clipsal is good quality, reliable, and can connect up to 40 other alarms for total coverage of your home.

On the downside, if you want to connect two or more alarms, an electrician is required.

Final word

Even though it's on the expensive side, we picked the Google Nest Protect as the best smoke detector because it's just so darn helpful. Beyond being able to detect carbon monoxide and different types of fires, the app removes the frustration that comes with typical fire alarms.
