High-performance garden shredder
A garden shredder is a convenient power tool to help shred your garden waste. By passing leaves, sticks and other garden waste through a shredder, you can reduce your garden waste into a more manageable pile that you can use around the garden.
There are tons of garden shredders in the market. Electric models are the most popular because they are easy to use. Petrol-powered units, on the other hand, are more powerful and suitable for heavier-duty tasks. To find the right option for your needs, consider your budget, if you want an electric or petrol option and the shredder's cutting capacity.
Our team has evaluated numerous garden shredders on Amazon and Bunnings to help your buying decision. For this list, we picked models based on customer ratings and reviews. We also considered each shredder's product features when choosing options for each category.
Read more detail on our methodology below.
The Ryobi AC 2400W Crushing Shredder comes highly recommended as a top-tier choice for garden shredders. It scores a remarkable 4.6 out of 5 stars on Bunnings.
This powerful machine is equipped with a 45mm cutting capacity, capable of effortlessly shredding large dry branches and foliage. Users have praised it for its silent operation and durable design, confidently turning thick branches and even wet leaves into useful mulch.
However, while this shredder showcases many strengths, it does have a couple of areas where it could improve. First, despite being fitted with two wheels, it can present challenges when moving it around the garden. And it demands unclogging every so often, making the shredding process somewhat time-consuming.
We chose the Ozito 2400W Corded Rapid Garden Shredder as the best cheap option to get online. Despite its affordability, it boasts an impressive 4.2 out of 5-star rating on both Bunnings and eBay.
This shredder has a 35mm cutting capacity and steel reversible blades that enhance cutting performance while prolonging the service life. The debris collection bag provided is a handy addition, simplifying the disposal of shredded material, which can also be used for composting in the garden.
However, potential buyers should know this machine might not be suitable for heavy-duty shredding. Moreover, while its 10:1 mulching ratio is excellent for accelerating composting and providing nutritional value to plants and garden beds, it may not handle denser, harder waste as effectively.
The Michigan Raptor Series 6HP 212cc Petrol Wood Chipper Shredder Mulcher stands out as the high-performance option, earning a rating of 4.5 out of 5 stars on Edison.
Its innovative upright design, powered by a robust 6HP 212cc engine, offers maximum efficiency due to its DirectDrive design. This machine can accommodate branches up to 76mm in diameter thanks to its side chute, and its self-feeding design makes it convenient for bushy foliage.
Plus, the heavy-duty steel construction and all-terrain pneumatic wheels ensure durability and ease of movement, while the handy dual-foot brake system enhances safety. But two factors to keep in mind are its relatively high price tag of $1,299 and the somewhat bulky nature of the unit.
Despite these cons, the Michigan Raptor Series comes with a bonus of goggles, ear muffs, and a collection bag, making it a comprehensive package if you're looking for serious power and innovative design in a wood chipper shredder mulcher.

Our team has also chosen the Ryobi AC 2400W Crushing Shredder as the best electric garden shredder. With a rating of 4.6 out of 5 stars on Bunnings, this option offers plenty of power, allowing you to handle large-diameter dry branches and palm fronds easily. And, with a 45mm cut capacity, it can take on even the toughest jobs in your garden.
Plus, the shredder features a translucent collection bin that allows for easy monitoring of your progress. So you don't need to keep stopping and starting throughout the job. Customers have also praised the machine for its low noise and energy usage, thanks to sensors that detect when there is no load and reduce the motor's RPM accordingly.
However, it's worth noting that this model is not ideal for wet garden off-cuts, as it is designed specifically to handle dry materials. You may also need to invest in an additional battery pack if you plan to use the shredder for long periods.
We also chose the Michigan 6HP 212cc Petrol Wood Chipper Shredder Mulcher as the best petrol option. On Edison, it has a rating of 5 out of 5 stars.
The upright design is paired with a seriously robust 6HP 212cc engine that delivers unparalleled performance. The machine's DirectDrive design ensures maximum efficiency, allowing users to tackle even the toughest wood-chipping tasks with ease.
Further enhancing its durability, the Raptor Series boasts heavy-gauge steel construction, ensuring longevity and resilience against wear and tear.
For those concerned about maneuverability, the 12-inch All Terrain Pneumatic Wheels ensure smooth navigation across various landscapes. Safety and utility haven't been overlooked either. The machine sports a convenient dual-foot brake system and side chute for branches up to 76mm in diameter. Additionally, its self-feeding design, featuring a drop-in bowl for bushy foliage, enables effortless operation. Even the packaging is impressive, with a tough reinforced crate ensuring secure delivery.
However, no product is without its drawbacks, and this model is no exception. The owner's manual could be more comprehensive, leaving some initial setup procedures unclear. Additionally, the lack of an electric start option may pose a challenge for some users, especially those unfamiliar with petrol engine equipment.

The Ozito 2400W Corded Silent Garden Shredder is a fantastic option for composting duties. With a rating of 3.8 out of 5 stars on Bunnings, this shredder is appreciated for its performance, especially considering its price point.
Thanks to its two-wheeled design, it gains top marks for its ease of use, value for money, and portability. It can easily shred plants, sticks, and branches into nutrient-rich waste, courtesy of its 35mm cutting capacity and steel reversible blades.
However, this shredder may not be as durable as some of the higher-end models in the market. Additionally, some users have reported it to be a bit noisier compared to other shredders. Yet, its price and performance continue to make it a popular choice among composting enthusiasts.
With a rating of 4 out of 5 stars on Amazon, the Ducar 8HP Petrol Garden Wood Chipper Shredder is an exceptional option to efficiently manage garden waste.
This machine is powered by an 8HP OHV 4-stroke 208cc petrol engine. Its high-performance features include a powerful cutting mechanism and heavy-duty 2400rpm blades made of hardened steel. These features ensure it can easily handle tough materials, such as branches and leaves, shredding them down to a manageable size. Additionally, the large, sturdy wheels and handle make it highly portable, allowing effortless maneuvering around the garden.
But know that quality comes at a price, and this wood chipper is no exception. The cost may be a bit steep for some gardeners. Furthermore, despite its high power, the unit might struggle to shred branches thicker than its 76mm (3 in) chipping capacity.
The Sun Joe Shredder Joe SDJ616 Electric Leaf Mulcher/Shredder certainly stands out as the best choice for handling leaf waste, bearing a strong Amazon rating of 4.2 out of 5 stars.
Its 13-amp motor combined with a bladeless mulching system proves to be a powerhouse, reducing yard waste to 1/16th of its original size. The device is also environmentally conscious, opting for electric power over gas, thus eliminating harmful emissions.
However, the unit's impressive processing rate of 55 gallons per minute may lead to frequent emptying of the collection bag, which could disrupt workflow. And despite its lightweight and compact design, the Shredder Joe's 19-inch hopper might pose a storage challenge for those with limited space.
The Michigan 2500W Electric Mulcher Crushing Garden Shredder Chipper is our choice for the best rotary option, earning a rating of 5 out of 5 stars on Edison.
The Michigan 2500W Electric Mulcher Crushing Garden Shredder Chipper is a remarkable powerhouse when it comes to outdoor maintenance. With its innovative upright design and a whopping 6HP 212cc engine, this machine makes quick work of garden waste. Its DirectDrive design ensures maximum efficiency, while heavy-gauge steel construction promises durability. The unit features 12" All Terrain Pneumatic Wheels and a convenient dual-foot brake system for enhanced mobility and safety.
Its capabilities are further amplified by a side chute for branches up to 76mm in diameter - perfect for those chunkier pieces of foliage. The self-feeding design comes with a drop-in bowl for bushy foliage. All these come in a tough, reinforced crate, and as a bonus, the package includes goggles, ear muffs, and a collection bag - everything needed for a safe and efficient gardening experience.
However, it requires relatively frequent maintenance to maintain optimal working conditions. This may not be a deal-breaker for everyone, but it does add to the overall time investment. Secondly, the machine requires regular oil changes. The specific oil type needed is 10W-30, and outdoor temperatures will determine the proper oil viscosity for the engine. This might be a bit more hands-on than what some users are accustomed to.
We recommend the GREATBULL 6.5HP Japanese Engine Chipper Shredder/Mulcher as the best high-end model.
This petrol shredder and mulcher is ideal for home or small acreage, providing a powerful motor for all your shredding needs. It features a Briggs & Stratton OHV 6.5HP engine and a dual function design for convenience. Additionally, it has a 75mm cutting capacity and an adjustable discharge chute. You'll also get a 3-year warranty for the engine and a 1-year warranty for the chipper.
While there are tons of more affordable options on the market, this machine offers superb power and cutting ability that lets you turn your garden waste into fine and rich mulch that you can use as fertiliser. It features carbon steel chipping knives and 20 flail hammers as well as a 3.8L fuel capacity. It also has 2 durable wheels for portability. But since the machine is quite heavy, moving it around can be a bit of a challenge.
We examined numerous garden shredders listed on Amazon and Bunnings for this list. We looked into models from the following brands:
We narrowed down our choices based on customer ratings and reviews (as of September 2023). We also considered each model's key product features, such as price, ease of use, and cutting capacity. We came up with what we believe are the 9 best garden shredders you can get in Australia right now.
There are a couple of ways to distinguish between the different types of garden shredders available. First, you can choose either an electric or a petrol-powered shredder:
Next, consider how the machine shreds garden waste:
Before you start shopping for a garden shredder, take some time to think about how you will use the machine. For example, how big is your yard? What's the maximum thickness of the branches you'll need to cut? How often will you be shredding? What's your budget?
Here are the key factors you'll need to take into account when comparing your options:
Petrol models are significantly more expensive than electric garden shredders. Electric models are generally priced between $150 and $500, but can be as much as $800. Heavy-duty petrol-powered shredders start at around the $800 mark and commonly cost more than $1,000.
Head in-store to take a closer look at how practical the shredder will be to use in the real world. Is the feed chute at a convenient height? Are all the controls easy to reach and understand? Will you be able to operate them while wearing gloves? Can you safely access the blades to clear any blockages? Is the opening wide enough for you to easily feed in garden material? How long is the power cord – will you need an outdoor extension lead?
Cutting capacity refers to the maximum branch diameter a machine is capable of shredding. This will typically be 40mm or 45mm for electric machines, but a little more for petrol models.
Another spec worth checking is the machine's noise rating, measured in decibels. Impact shredders are louder than roller shredders and may not be the best choice if your neighbours are particularly sensitive to noise.
Safety is an essential consideration when using any garden power tool. Garden shredders can be quite dangerous if used incorrectly, so make sure you follow the manufacturer's instructions for proper and safe use.
You'll also need to wear basic safety gear (goggles, ear muffs and gloves) when using one of these machines, and ensure that there are no kids, other people or pets in the immediate area. And if you ever need to clear a blockage, make sure you fully switch off and unplug the unit before you start work.
