Find a Trusted Arborist
in Perth's Western Suburbs

Twelve suburbs, seven local governments, and the answer to "can I take this tree down?" changes when you cross the street. Six of them sit together in the Western Suburbs Regional Organisation of Councils, a voluntary partnership, with the Town of Cambridge attending as an observer. Four of them now want a development application before a big tree comes off private land: Cambridge, Nedlands, Mosman Park and Peppermint Grove. No two of them define a big tree quite the same way.

The borer has drawn the second line. All seven councils are named in the Management Zone schedule of the polyphagous shot-hole borer quarantine notice without qualification, where Swan, Kalamunda, Armadale, Wanneroo, Rockingham and Mundaring are each written in only for named localities. Being inside that zone decides who pays when a tree gets hit, and it decides how the wood leaves your street. The arborists listed below quote against those rules every week. Browsing and contacting them is free.

We could not find a first-party or industry-body price survey for Western Australia, so these are published trade figures rather than measured averages. The removal, stump and report bands come from a Perth cost guide and its companion arborist page, which cannot agree with itself on an average removal: $1,290 on one, $1,100 on the other. The spread is the honest answer; neither number is. That publisher also says the trade here prices whole jobs, not hours, which is why no hourly cell appears above. Palm bands are a Perth operator's own guide, set by height and access rather than by species. One local cost most quotes forget: green waste from this corridor has to leave in sealed transport, so ask whether cartage and disposal are inside the number.

Advice

Six things worth checking before you book

Four of the seven can say no

Cambridge's LPP 3.25 (in effect 11 December 2024), Nedlands' LPP 3.3 and 3.4, Mosman Park's LPP 43 and Peppermint Grove's LPP 7 all require approval for "tree damaging activity" to a regulated tree: killing, removing, severing limbs, ringbarking, topping or lopping. Height of 8m or a canopy near 6m triggers all four. The trunk figure is where they part, at 1m circumference in Cambridge and 1.5m in the other three.

The overhanging branch rule flips in Cambridge

Everywhere else in the state, an unprotected branch reaching across the boundary is yours to trim at the line and nowhere past it. Cambridge spells out what its policy does to that right: where the tree is regulated, pruning the overhang needs approval unless it is maintenance pruning, meaning dead or diseased wood, limbs under 100mm, or under a tenth of the canopy in 12 months. In Peppermint Grove, by contrast, a branch encroaching into common property may be lopped without approval.

Inside the Management Zone, the borer job is yours to book

DPIRD now points its own pruning and removal program at the outer metropolitan area and says every other landowner in Perth is responsible for managing borer-affected trees. So you engage the crew. Untreated, unseasoned wood also cannot simply be driven out of the zone: chipping it to 2.5cm or smaller is one lawful route out, and delivering it to a council waste facility, sealed and covered for the trip, is another.

There is $150 back on what you plant next

Two state rebates run through the ServiceWA app. Treebate pays up to $150 for a native tree whose canopy will reach at least three metres at maturity. The WA Tree Recovery Program pays up to $150 per replacement where the original came out under departmental authority because of the borer, and it will not fund a box elder maple, coral tree or robinia. Keep the tax invoice and photograph the plant label.

Diagnosing the tree is on you, not the council

Peppermint Grove states flatly that it does not engage arborists to assess the health of private trees, or engineers to assess risk to buildings. Mosman Park puts dieback testing on private land onto the resident. Claremont will recommend an arborist and says the consultancy is paid for by the resident. Budget the assessment as its own line, separate from the works.

A tree lopper cannot write your report

If an application needs an arborist report, the qualification is not a detail. Nedlands defines the report as the work of an arboriculturist holding at least a Diploma of Horticulture (Arboriculture) at AQF 5, and states that a tree lopper without those qualifications does not meet the definition. Worth pairing with the insurance floor: $5m of public liability is the minimum for registration with Arboriculture Australia, plus $2m of professional indemnity for the grades that write reports. Three grades exist, not two, and none of it is a licence, because the trade is unregulated.

FAQ

Frequently asked questions

Do I need council approval to remove a tree on my own property in Perth's western suburbs? +
Four of the seven now say yes, and they do not agree on where the line sits. Cambridge, Nedlands, Mosman Park and Peppermint Grove each require development approval for tree-damaging activity to a regulated tree on private land. All four are triggered by a height of 8m or a canopy around 6m. The trunk measurement is where they split: Cambridge counts a single trunk of 1m circumference at 1.4m above the ground, while the other three use 1.5m, and Peppermint Grove alone requires a tree to satisfy two of its three qualifiers rather than any one of them. Cambridge and Nedlands add a separate test for multi-trunk trees, and Nedlands splits its rules by density code, so the policy that applies to you depends on your zoning. Two exemptions are worth knowing: all four exclude species on a weed register, and Nedlands and Mosman Park both state that palms fall outside the definition of a tree altogether. Claremont's adopted tree policy reaches only trees the Town owns or manages, though it advertised a tree-retention policy of its own in 2025 which had not reached its published policy register when we checked. We could not get the Subiaco or Cottesloe planning-policy registers to load, so treat those two as unconfirmed rather than clear, and ring the council before you book a crew.
How much does tree removal cost in Perth's western suburbs? +
The bands in the grid above are Perth-wide, and that is deliberate: the cost guide behind those bands says your location inside the metropolitan area moves the needle only slightly. A Peppermint Grove quote should not open above a Perth average on the postcode alone. Access is what genuinely moves the number here. Older lots run narrow and deep, several streets are served by rear laneways, the ground falls away toward the river on the Dalkeith and Mosman Park side, and overhead power still runs through a lot of canopy. Whether a chipper can park beside the tree or the timber has to be carried out by hand is worth more to the price than the suburb name.
Can I cut back a branch that overhangs my fence? +
In most of Western Australia the answer is a straightforward yes, and Legal Aid WA sets out the limits: trim at the line, never past it, and hand the offcuts back. This corridor carries an exception. In the Town of Cambridge, where the tree next door meets the definition of a regulated tree, development approval is needed to prune even the part hanging over your side, unless the work counts as maintenance pruning: dead or diseased wood, limbs under 100mm, or no more than 10 per cent of the canopy in any 12 months. Peppermint Grove reads the other way and lets an encroachment onto common property be lopped without approval. Speak to the neighbour first, then check the tree's status with the council, because the cost of getting this wrong is not the pruning bill.
My tree has shot-hole borer. Who is responsible for dealing with it? +
You are. All seven councils here sit inside the borer's Management Zone, and the department has said its own pruning and removal program now concentrates on the outer metropolitan area, with every other landowner and manager in Perth responsible for managing borer-affected trees themselves. So the removal is a private job, booked and paid for like any other. Disposal changes too. Untreated, unseasoned wood only crosses out of the Management Zone once it has been chipped down to 2.5cm or smaller, and a load headed for a council waste facility travels sealed and covered. That is a real line in a quote, not a formality, so ask who is carrying it and where to. If a tree does come out under the department's authority, the state's replanting rebate is worth up to $150 per replacement tree.
Can I prune or remove the tree on my verge? +
No, and each council says so in its own words. Subiaco requires written approval before pruning, damaging or removing a tree on council property and warns that without it you may be committing an offence. Mosman Park does not permit residents to prune or remove street or park trees at all, and will not take one out unless it is dead, dying or diseased. Peppermint Grove owns its entire stock of street trees, plants the peppermint tree as its standard species, and makes the applicant carry the cost of any removal or replacement it agrees to. Nedlands looks after roughly 18,000 street trees and wants removal requests in writing. If a verge tree is the problem, the request goes to the council, not to a contractor.
How do I find a good arborist near me in the western suburbs? +
Ask the four questions the rules here have made expensive to get wrong. Which of the seven local governments is the property in, and is the tree regulated where you are? Who is carting the timber away, and to which waste facility? Is the stump in the price or extra? And is the crew set up for sealed green-waste transport and for work near power lines? Someone who works this corridor answers all four without looking anything up. Two or three tree removal quotes written against the same scope will tell you more than any single number will.
