Stump Grinding Cost in Australia 2026 — Per Stump and Per Metre
Once a tree is down, the stump is often left behind — and it's more than an eyesore. Stumps can harbour termites, fungal disease, and trip hazards, and many councils won't sign off on a landscaping project until they're gone. Stump grinding is the fastest, cleanest removal method, with most Australian arborists charging $80–$800 per stump depending on diameter, species, grinding depth, and site access.
A stump grinder — either a drum-type or disc-type machine — uses a rotating cutting wheel to shred the stump and surface roots into wood chip. The process leaves a shallow crater of mulch that you can backfill with soil, spread in garden beds, or leave to decompose. Most residential jobs take under an hour per stump once the machine is on-site.
This guide breaks down Australian stump grinding costs by diameter, explains the difference between surface and full-depth grinding, covers the hardwood premium, and helps you navigate access surcharges and multi-stump discounts.
Last updated: May 2026.
Key takeaways
- Small stumps under 30cm cost $80–$150; very large stumps over 90cm run $400–$800+.
- Hardwood species (ironbark, spotted gum, tallowwood) add 20–30% — denser timber dulls cutting teeth faster.
- Grinding depth: surface grind (5–10cm) suits lawn reinstatement; 20cm suits turf or garden beds; 30cm+ is needed for replanting.
- Access surcharges of $50–$150 apply for narrow gates, slopes, or tight spaces.
- Multiple stumps in one visit attract 15–25% discounts — the machine is already mobilised.
- Always use a qualified contractor carrying public liability insurance.

Stump grinding cost by diameter — price table {#price-table}
Diameter is the single biggest driver of stump grinding cost in Australia. It determines how long the machine runs and how much cutting wear the contractor absorbs. These estimates are drawn from rates modelled through Leadkit's stump removal cost calculator using current contractor pricing across Australian capital cities and regional markets.
| Stump diameter | Typical trees | Price range (inc. GST) | With access surcharge |
|---|---|---|---|
| Small — under 30cm | Ornamentals, young natives, fruit trees | $80–$150 | $130–$300 |
| Medium — 30–60cm | Mature garden trees, mid-size gums | $150–$300 | $200–$450 |
| Large — 60–90cm | Large eucalypts, Brush Box, Camphor Laurel | $250–$500 | $300–$650 |
| Very large — 90cm+ | Old-growth gums, Moreton Bay Figs, ironbark | $400–$800+ | $450–$950+ |
| Call-out / minimum fee | Per visit (applies to single small stumps) | $80–$150 | — |
| Access surcharge | Narrow gate, slope, tight space | $50–$150 | — |
| Chip/mulch removal | Take away (vs leave on site) | $50–$150 | — |
| Hardwood premium | Ironbark, spotted gum, tallowwood | Add 20–30% | — |

Grinding depth options and cost {#grinding-depth}
Grinding depth depends on how you plan to use the area afterwards. Deeper work takes more time and tool wear — and costs accordingly.
Surface grind (5–10cm below grade)
Removes the visible stump to just below lawn level. Suits lawn reinstatement or bark mulch beds. Root systems are left to decay naturally over one to five years. Cost impact: Included in base price.
Partial grind (20cm below grade)
Sufficient for turf, pavers, or garden beds planted with shrubs. Cost impact: Add $20–$80 depending on stump size.
Full replanting depth (30cm+ below grade)
Required if you plan to replant a tree in the same spot. Generates a larger chip volume and takes significantly longer per stump. Cost impact: Add $50–$150 depending on diameter and hardness.
This is a price indication only. Your tradie will confirm the final price after assessing the job.
Hardwood vs softwood stump cost difference {#hardwood-softwood}
One of the most consistent cost variables in Australian stump grinding is timber density. Hardwood stumps cost 20–30% more to grind than softwood stumps of the same diameter, and the reason comes down to machine wear and cutting time.
Why hardwood costs more
Hardwood species like ironbark, spotted gum, tallowwood, and Brush Box have extremely dense, interlocking grain that resists cutting. A drum-style stump grinder's carbide teeth dull significantly faster on hardwood, and operators often need to swap teeth mid-job or slow the machine's feed rate. Disc-style grinders (common on commercial Husqvarna and Vermeer models) handle hardwood better but still require more time per centimetre of depth.
A disc-type stump grinder uses a horizontal cutting disc mounted on an arm, allowing the operator to sweep the grinding head back and forth across the stump. A drum-type grinder uses a vertical drum with cutting teeth arranged in rows — it's faster on softwood but can bog down on dense hardwoods.
Common Australian hardwood trees
Species consistently attracting a hardwood premium include: ironbark (Grey and Red), spotted gum, tallowwood, jarrah and Karri (prevalent in WA), and Brush Box (common in eastern urban plantings). Soft-timbered species — jacaranda, golden robinia, ornamentals, and most fruit trees — grind quickly and sit at the lower end of each price band.
Access and site factors {#access-factors}
After stump diameter, site access is the factor most likely to push your quote above the base rate. Stump grinding machines range from compact walk-behind units (which can fit through a standard 900mm gate) to large self-propelled machines that need a 1.2m+ opening. If the machine can't reach the stump directly, costs increase.
Narrow gate or fenced backyard
Gates under 900mm wide require the contractor to hand-carry a compact grinder through the house or over the fence. Access surcharges of $50–$150 are typical in this scenario.
Slopes and uneven ground
Steep or uneven terrain affects machine stability. Contractors working under Safe Work Australia guidelines must assess equipment use on slopes before commencing. Sloped sites typically add 15–25% to the base price.
Proximity to structures and utility lines
Stumps within 1–2 metres of a foundation, retaining wall, or pool require a more controlled approach. Underground services must also be verified via a dial-before-you-dig check before grinding commences.
Chip/mulch disposal
Grinding produces 3–5 times the visible stump volume in wood chip. Most contractors leave the chip on-site to mulch and decompose over 2–3 years. Carting it away typically adds $50–$150 depending on volume.
Multiple stumps discount {#multiple-stumps}
If you have more than one stump to grind, booking them together on the same visit almost always saves money. Once the machine is on-site and set up, each additional stump costs the contractor less time and overhead than a separate call-out.
Most Australian contractors apply a 15–25% discount on per-stump pricing for three or more stumps in one visit, with the call-out minimum either waived or absorbed into the bundle. The first stump attracts the call-out fee; each additional stump is priced at a lower incremental rate.
Leadkit's stump removal cost calculator accounts for multi-stump volumes. If you've recently had trees felled, bundle the grinding job rather than booking each stump separately.
Stump grinding vs chemical removal vs manual extraction {#comparison}
Three main methods exist, each with a different cost, timeframe, and use case.
| Method | Cost range | Timeframe | Best suited to |
|---|---|---|---|
| Stump grinding | $80–$800+ | 1–4 hours | Most residential and commercial stumps |
| Chemical removal | $20–$80 DIY; $50–$150 pro | 6–18 months | Remote locations, non-urgent removal |
| Manual extraction | $200–$600 labour | Half–full day | Small stumps in friable soil |
Stump grinding is the fastest and cleanest method for most residential situations. Wood chip mulch remains on-site and the root system below grinding depth decays naturally.
Chemical removal is low-cost but slow — typically 6–18 months before the stump softens enough to break apart. Not suitable if you need to replant or build over the area. The International Society of Arboriculture (ISA) notes that chemical accelerants work best on freshly cut stumps.
Manual extraction is labour-intensive and only practical for small stumps in friable soil — large root systems extend well beyond the drip line and are extremely difficult to remove without machinery.
DIY stump grinder hire vs professional {#diy-vs-pro}
Stump grinder hire costs $200–$450 per day for a self-propelled walk-behind unit from most equipment hire companies. On paper this looks cheaper than a professional — in practice, the comparison is less straightforward.
DIY hire — what it actually involves
Walk-behind rental grinders weigh 200–400kg and require experience to manoeuvre safely. Safety equipment (face shield, hearing protection, heavy gloves) is mandatory — the grinding head throws debris at high velocity. Cutting teeth dull quickly on hardwood and may need replacing mid-job at an additional hire cost. You're also responsible for underground service damage and chip disposal (add skip bin or trailer hire).
When DIY makes sense
DIY hire suits two or more soft-timbered stumps on an accessible flat site with no nearby structures or utilities. Arboriculture Australia recommends consulting a qualified arborist first to assess root depth relative to underground services before any DIY stump removal.
When to use a professional
For hardwood stumps, stumps near structures or utilities, access limitations, or any stump over 60cm diameter, professional grinding is almost always better value once you factor in hire cost, time, and risk. Professionals using commercial Husqvarna or Vermeer grinders complete jobs significantly faster than hire equipment allows.
FAQs {#faqs}
How much does stump grinding cost per stump in Australia?
Stump grinding costs $80–$150 for small stumps under 30cm diameter, $150–$300 for medium stumps (30–60cm), $250–$500 for large stumps (60–90cm), and $400–$800+ for very large stumps over 90cm. A call-out minimum of $80–$150 typically applies to single-stump jobs. This is a price indication only. Your tradie will confirm the final price after assessing the job.
Does stump grinding remove the roots?
Grinding removes the stump and surface root system to the selected depth (5–30cm). Deeper roots are left in the ground and decay naturally over one to ten years. Request 30cm+ depth if you plan to replant a tree in the same spot.
How long does stump grinding take?
Most stumps take 20–60 minutes once the machine is positioned. A large hardwood stump may take 2–3 hours. A contractor typically handles 8–15 stumps in a full day depending on size and access.
Is stump grinding messy?
It generates wood chip roughly 3–5 times the visible stump volume. Chip can be left on-site as mulch or carted away. The grinding head also throws debris, so clear the immediate area and protect nearby glazing before work starts.
Do I need council approval to grind a stump?
In most councils, grinding a lawfully removed tree's stump doesn't require separate approval. However, if the original removal was under a council permit, check whether the permit conditions address stump treatment. Always verify with your local authority.
What's the difference between a drum and disc stump grinder?
A drum-type grinder uses a vertical cylindrical drum with carbide teeth — fast on softwood but can bog on dense hardwood. A disc-type grinder (common on commercial Husqvarna and Vermeer models) uses a horizontal cutting disc on an articulating arm, allowing a wide sweep and better hardwood performance.
Conclusion {#conclusion}
Diameter, species, depth, and access are the four variables that put your job in the $80–$800+ range. Hardwood premiums and access surcharges push costs up; multi-stump discounts pull them back down.
