That’s why we’ve put together this all-in-one guide on weed sprayers for Aussie homeowners and landowners. From basic hand-held units to heavy-duty tow-behind sprayers, we’ll break down the best options to help you tackle those weeds once and for all.
What Is a Weed Sprayer?
A weed sprayer is a device used to apply herbicides and other liquids across lawns, gardens, and large outdoor areas. It helps distribute the spray evenly, saving time, effort, and money compared to manual application.
Modern weed sprayers come in all shapes and sizes, from small backpack sprayers to large trailer-mounted tanks. Choosing the right one depends on your land size, power source, and how frequently you need to spray.
Types of Weed Sprayers
Let’s go through the most popular types of weed sprayers available for sale in Australia, including what they’re best suited for.
1. Battery Powered Weed Sprayer
Battery powered weed sprayers are one of the most convenient options around. With no need to pump manually or mess around with fuel, they’re perfect for small to medium-sized jobs.
Look for models listed as weed sprayer battery or weed sprayer battery powered. These typically run on rechargeable lithium-ion batteries, giving you consistent pressure with minimal effort.
Best for: Home gardens, small blocks, spot spraying
2. 12V Weed Sprayer
The weed sprayer 12V or weed sprayer 12 volt is a popular choice for ute, quad bike, or ATV mounting. These sprayers plug into your vehicle’s 12-volt battery and are perfect for larger properties where portability is key.
They usually come as part of a weed sprayer unit that includes the tank, pump, hose, and wand, and can often be fitted with a boom sprayer kit for even coverage over wider areas.
Best for: Acreage owners, hobby farmers, large gardens
3. Trailer Mounted Weed Sprayer
If you’ve got a lot of ground to cover, a trailer mounted weed sprayer is the way to go. These are heavy-duty units that can carry 100L or more in capacity. Simply hitch the weed sprayer with trailer to your ATV, quad bike, or ride-on mower and get to work.
Trailer weed sprayers are a godsend for spraying large lawns, driveways, paddocks, or firebreaks. They’re especially useful when fitted with a weed sprayer boom for wide coverage.
Best for: Larger properties, small farms, commercial applications
4. ATV and Quad Bike Weed Sprayers
Weed sprayer ATV models and weed sprayer for quad bike options are designed to fit securely to your vehicle’s rear tray or rack. They’re rugged, reliable, and a favourite among rural Aussies.
Some setups include a boom or wand, giving you flexibility whether you’re spot spraying or blanketing large areas.
Best for: Farms, bush blocks, roadside spraying
5. Weed Sprayer Tank and Trolley Systems
For those who prefer not to carry the load, a weed sprayer trolley is a compact, wheeled alternative that’s easy to push around your property. Meanwhile, a weed sprayer tank and pump setup gives you the power to mount it however you like—on a ute tray, in a trailer, or as part of a DIY kit.
Tanks range in size, with weed sprayer 100L being a common capacity for serious spraying jobs.
Best for: Versatility and custom setups
