Do I Need a Dash Cam? A First-Timer's Guide for Aussie Drivers
You have been thinking about a dash cam, but a little voice keeps asking, do I need a dash cam at all? Your car already has a reversing camera, you are a careful driver, and nothing bad has ever happened. Fair enough. Those are the exact thoughts nearly every first-time buyer has, and they are worth answering properly.
So let us clear up the most common myths in plain English, with no sales pressure. By the end, you will know whether a dash cam is right for you.
First things first: what is a dash cam?
A dash cam is a small camera that mounts to your windscreen and records the road while you drive. It starts on its own when you turn the car on, and it records in a loop, which just means it keeps filming and writes over the oldest footage once the memory card is full. You never have to press a button. If something happens, you have a clear video of it.
That is the key word here: proof. A dash cam is your quiet witness on the road.
Do I need a dash cam if my car already has cameras?
This is the big one, and it is easy to get mixed up. The camera built into your car is a reversing camera, sometimes called a backup or 360 camera. Its only job is to show you a live picture on your dashboard screen while you park or reverse at low speed. The moment you shift into drive, it switches off. It does not record anything, and it does not save footage.
A dash cam does the opposite. It faces the road, it runs the whole time you are driving, and it saves everything. So even with a factory reversing camera, you still have no recording of the road in front of you. Same word, camera, but completely different jobs.
I'm a careful driver, so why do I need a dash cam?
This is the most common reason people give for skipping one, and it makes sense. But a dash cam was never meant to stop accidents. It is there to record what happened when one does. You might be a great driver, but you cannot control the other people on the road.
If someone runs a red light and hits you, it can quickly become your word against theirs. That is the he-said, she-said blame game, and it is stressful. A dash cam settles it. Insurers and police are happy to look at clear footage, because it shows exactly what happened. It protects careful drivers most of all.
My car just sits parked, do I still need one?
Plenty of damage happens when you are nowhere near the car. Trolley dents in the shopping centre car park, someone reversing into your bumper and driving off, or a key scratch down the side. You come back, find the damage, and have no idea who did it.
Many dash cams have a parking mode, which means the camera keeps watching over the car after you switch the engine off. If something bumps or moves the car, it records the moment. So your dash cam earns its keep even while you are inside doing the groceries.
Won't my phone or GoPro do the job?
You can point a phone or a GoPro at the road, but they are not built for it. You have to remember to start them every single trip, and it only takes one forgotten drive to miss the moment that mattered. They also hate heat. Left on a windscreen through an Aussie summer, they overheat and shut down. A dash cam is designed to start and stop on its own and to keep recording in the heat. We go deeper on this in our GoPro versus dash cam guide.
Isn't a dash cam just for Uber and taxi drivers?
Rideshare drivers do love them, and for good reason, but they are far from the only ones. New P-platers, families sharing one car, tradies and everyday commuters all get the same benefit: a clear record if something goes wrong. If you have just handed the keys to a teenager, a dash cam is peace of mind for the whole family. Rideshare drivers can see our rideshare dash cam guide for cabin-camera options.
Pro Tip: If you only remember one thing, make it this. A dash cam is not about expecting a crash. It is about having proof if one ever finds you. That single video can save you months of stress and a lot of money.
So, do I need a dash cam?
If you drive on Australian roads, share the road with people you cannot control, or ever leave your car parked in public, then yes, a dash cam is one of the smartest and cheapest bits of protection you can add. It quietly does its job and stays out of the way until the day you really need it.

Last reviewed: 19 August 2026. We do not sell GoPro, and anything said here about how a GoPro behaves as a dash cam is based on GoPro's own published specifications and on what owners have told us, not on our own testing. GoPro change that behaviour with firmware, so check their current specifications before you buy one for this purpose. If a specification, a feature or a price on this page is wrong or has gone out of date, tell us and we will correct it.
