Worried your shiny new generator might vanish faster than a free sausage sizzle at Bunnings? The short answer: you can't make generators completely theft-proof, but you can make them very hard to pinch. With the right mix of locks, barriers, and smart tech, you'll turn your generator into more trouble than it's worth for any thief. Stick around—this guide unpacks practical ways to keep your investment safe.
Not sure which generator is right for you?
Take the quiz!
Generators fetch a tidy price on the resale market, which makes them an easy win for crooks. Add to that their portability—many are portable generators with compact frames and wheels designed for convenience—and you've basically got an item that can be carted off in minutes.
Leave a generator sitting around without locks, barriers, or markings, and it might as well have a sign saying "take me." Unlike larger machinery, they're quick to move, and many people don't secure them properly, which only fuels the problem.
Picture this: you run into town for supplies, leave your generator in the backyard or at a campsite with a camping generator, and come back to find it gone. That's opportunistic theft in action—fast, unplanned, and taking advantage of carelessness.
Some thieves aren't just lucky chancers. They keep an eye out for high-value models, scope out properties, and come back with the right gear to move them. If they think a certain model is worth the effort, they'll plan ahead.
One of the cheapest ways to make life hard for thieves is to anchor your generator. Heavy-duty chains connected to a fixed post or even concrete anchors turn a quick grab into a noisy, time-consuming job.
A simple timber or steel enclosure adds a barrier that most thieves won't bother with. A padlocked access door gives you usability while making it a nightmare for anyone trying to get in without permission.
Anti-theft brackets are made for one job—keeping your generator bolted down. They're designed so thieves can't just slide it free, forcing them to either give up or make a racket trying.
If your generator stays in one place, a permanent installation is worth it. Not only does it lock the unit down, but any attempt to remove it usually leaves signs of tampering that hurt its resale value.
A properly built cage made of steel makes your generator look more like a safe than a target. Strong welds and tamper-resistant locks give you an edge, especially in areas where theft is common.
Don't forget airflow—cages need ventilation to stop overheating. A good design also makes sure you can refuel and maintain your generator without having to dismantle half the structure.

At campsites, a generator is as tempting as leaving an esky of cold beers unguarded. Lock it to something that can't be moved—a tree, vehicle, or solid post—and you'll make it far less appealing.
In remote spots, use layers. A chain and padlock, a cover to keep it out of sight, and a secondary lock or alarm. Each barrier adds more hassle for thieves.
The classic chain and padlock combo still works when you choose quality gear. Hardened steel chains and closed-shackle locks resist bolt cutters, buying you precious time.
Sometimes the best trick is keeping it out of sight. A generator stored behind a shed, under a cover, or away from road view avoids drawing the wrong kind of attention.
Attach a motion-triggered alarm and you'll know the second someone fiddles with your generator. The noise alone is enough to scare off most thieves.
A hidden GPS tracker is your insurance policy. If someone does manage to get away with your generator, you can track it in real-time and hand the details to police.
A well-lit, camera-covered spot makes thieves nervous. Motion lights expose them instantly, and CCTV footage gives you evidence if the worst happens.

On Reddit and similar forums, you'll find Aussies sharing what's worked for them—everything from burying anchor bolts in concrete to disguising a generator as a rusty old box. These little hacks are often cheap and clever.
The biggest mistakes? Relying on flimsy locks, leaving generators visible from the street, and failing to register serial numbers. Communities often stress the basics that owners overlook.
Engraving your name, using UV pens, or registering the serial number gives police something to work with if your generator is stolen. It also makes resale harder for the thief.
Don't forget the fuel. Lockable fuel caps and keeping spare cans secured reduces losses from petty theft and saves you from frustrating surprises.
The real secret is layering. A cage, plus a lock, plus lighting, plus marking—none of these alone is perfect, but together they make your generator far too much hassle for most thieves.
No generator is 100% theft-proof, but with the right mix of strategies, you can tip the scales heavily in your favour. Anchor it, cage it, watch it, and mark it. Combine these tactics, and you'll make stealing your generator so inconvenient that most thieves won't bother. Peace of mind comes from knowing your backup power is where it belongs—safe, secure, and ready when you need it.
