Block slashing
Block slashing and firebreaks in Perth
When growth on a block is waist- or chest-high, it has stopped being a mowing job. Block slashing is the heavy-machinery version: we cut the whole lot down in one pass, from a single overgrown suburban lot through to acreage and large commercial sites.
It is also how firebreaks get cut. If you own land in Perth's southern corridor you almost certainly have a firebreak obligation from your local government each fire season, and the slots to get it done fill up. Book ahead of your council's deadline rather than after it.
What we slash
- Vacant and overgrown blocks
- Single suburban lots that have been sitting between builds or between owners, cut back to a flat, walkable, inspectable surface.
- Firebreaks
- Perimeter breaks cut to the width and position your local government requires. Tell us the requirement in your notice and we'll cut to it.
- Acreage and semi-rural
- Larger parcels where the job is measured in hours of machine time rather than square metres. Paddocks, house blocks on acreage, and the strips between.
- Commercial and development sites
- Sites needing to be presentable or accessible — before an inspection, a valuation, a sale, or the start of works.
- Pre-sale and pre-build clearing
- A block that can actually be walked photographs and sells very differently to one you can't get into.
Slashing cuts growth down. It is not a clean-up: rubbish, debris and dumped material need to come out before we can safely put a machine over a block.
When you need slashing done
The hard deadline is fire season. Local governments across the Perth metro area issue an annual firebreak and fuel-load notice, with a date by which breaks must be cut and maintained. The exact width, position and dates differ by council and by property size, so the notice you receive is the authority — not us. What we can tell you is that everyone gets the same notice at the same time, so the weeks before the deadline are the busiest of our year for this work. Book early and you get a choice of dates.
Outside fire season, the trigger is usually a transaction or an inspection. A block going to market. A settlement approaching. A council or insurer letter about fuel load or an unsightly-land notice. A builder needing a site they can actually set out on.
The third trigger is simply that it has got beyond a mower. If growth is above knee height across an open area, a slasher will do in one visit what a mower would struggle with all day, and the result is more even. Once the block is down, keeping it down is ordinary lawn mowing — and if the growth is really a garden gone feral rather than open ground, that's a garden clean-up.
How it works
- 01
Send the address, size and photos
The street address, the approximate block size, photos showing the height of the growth, and how a machine and trailer would get on. If you have a firebreak notice, send the requirement with it. Use the enquiry form.
- 02
We quote from size and access
Slashing is quoted upfront from the block size, growth height and access — that's the whole calculation. Larger or blind sites get a look first. No callout fee.
- 03
We cut it
Most suburban blocks are a single visit. You get finished photos, which is what you need anyway if you're demonstrating compliance to a council or an insurer.
Areas we cover
Block slashing runs across the southern corridor and out to its semi-rural edges — the parts of our patch where there is most vacant and acreage land. The service areas page has the full suburb list.
In practice the heaviest slashing demand is on the outer and newer edges of our area rather than the established inner suburbs: the Atwell, Success, Treeby, Banjup and Wandi belt, and the south edge around Bertram, Wellard, Mandogalup and Hope Valley, where blocks are bigger and more of them are still vacant. Around Cockburn Central it's typically lots between builds. In tightly built-out suburbs like Spearwood and Bibra Lake there is less vacant land, so it's usually a single lot rather than a run of them.
What slashing costs
Slashing is one of the more predictable things we quote, because the inputs are simple: how big the area is, how high and how thick the growth is, and whether a machine can get on and move around freely.
Height and density matter more than people expect. Knee-high grass is a fast single pass. Chest-high woody growth is slower, may need two passes, and is harder on the machine. Slope, soft sand and uneven ground all slow it down as well.
The things that genuinely add cost are obstacles and hazards: star pickets, wire, dumped rubbish, concrete, tree stumps and star droppers hidden in long grass. A hidden stump can wreck a slasher, which is why we ask what's under there — and why a block with known debris may need a hand-clear first. Access is the last piece: a block with a wide open frontage prices better than one behind a locked gate on a narrow verge.
Firebreaks are your legal obligation, not ours
Firebreak width, position, timing and penalties are set by your local government and stated in the notice they send you each year. Requirements vary between councils and by property size. We cut to the specification you give us. Check your own notice — or your council's website — and get in touch well before the deadline, because the last fortnight before it is when everyone calls at once.
Block slashing FAQs
Do you cut firebreaks and slash overgrown blocks?
Yes. We slash overgrown blocks and cut firebreaks across Perth's southern suburbs, from a single suburban block through to acreage, using heavy machinery. Jobs are quoted upfront from the block size and access. Fire-season slots fill up, so book ahead of your council's firebreak deadline rather than after it.
How wide does my firebreak need to be?
That's set by your local government, not by us, and it differs between councils and by property size. Your annual firebreak notice states the requirement — send it to us with your enquiry and we'll cut to it.
When should I book fire-season slashing?
As early as you can. Every landowner in a council area receives the same notice with the same deadline, so demand is concentrated into the weeks before it. Booking early is the difference between choosing your date and taking what's left.
Do you take the cut material away?
Slashing mulches growth down and leaves it on the ground — that's what makes it economic on a large area. If you need the material collected and carted off, say so in the enquiry: it's possible on smaller blocks but it's a different job and a different price.
What if there's rubbish or debris on the block?
Tell us before we quote. Hidden stumps, star pickets, wire and dumped rubbish are a genuine hazard to a slasher and to the operator, so a block with debris needs clearing first. We'd rather know from a photo than find out with a blade.
Can you slash a block I don't live near?
Yes — a lot of this work is for owners of vacant land who live elsewhere. You never need to attend. We work from the address, quote from photos and satellite, and send finished photos you can forward to a council or insurer.
