Find a Trusted Arborist
in the Perth Hills
Twenty-four kilometres east of Perth the ground tips up into the Darling Range and the gardens change with it. The City of Kalamunda describes its own patch as old growth jarrah and marri forest split three ways — a foothills strip, an Escarpment holding Kalamunda, Lesmurdie and Gooseberry Hill, and an Eastern Rural District taking in Bickley, Walliston and Pickering Brook — and says the escarpment and rural east are wetter than Perth, pulling over 1,000 millimetres of rain a year. Over the boundary the Shire of Mundaring calls the jarrah–marri forest its main native vegetation type and part of an internationally recognised biodiversity hotspot, with wandoo, yarri, sheoak and banksia in localised woodlands through it. Hardwood, slope and rainfall are what make a tree job up here different from one on the plain.
They are also separate rulebooks, and the differences are not small. Mundaring requires Shire approval to take out any native vegetation on a private block — trees, shrubs, herbs and grasses — with carve-outs for perimeter firebreaks and for lots too small to keep bushland on. Kalamunda went the other way and now lists Local Planning Policy 33: Tree Retention among its revoked policies. Different again for Roleystone, where the City of Armadale's yearly Bush Fires Act notice is the document that actually orders the cutting, and suggests the Roleystone green-waste facility as one place the vegetation can go — a fire instrument, not a tree one. Which side of a line your driveway is on changes the answer more than the tree does.
Typical pricing in the Perth Hills
Nothing published prices the Hills separately, so the figures above are city-wide. One quoting service averages a Perth removal at $1,290 and steps its sizes at 5m, 9m, 20m and 50m; a second page on the same site averages $1,100, opens at $350, and puts a one-tree report for a council application between $300 and $450. One publisher, two answers — treat the grid as a shape, not a price. Asked outright whether the Hills costs more than the flat suburbs, that publisher says geography barely moves it and a local crew is the cheaper bet. The column that actually matters up here is the 20m-plus one: mature marri and jarrah on a sloping acre, a long carry back to the truck, and a quarantine that decides what happens to the timber afterwards. The shot-hole borer notice, in force until 11.59pm on 31 December 2026, draws its Management Zone through the Shire of Mundaring by locality — Bellevue, Boya, Darlington, Glen Forrest, Greenmount, Helena Valley, Hovea, Mahogany Creek, Midvale and Swan View, and no others — while taking in Kalamunda apart from parts of Pickering Brook and Reservoir east of Ashendon Road. Untreated wood moves freely inside the Management Zone but cannot leave it unless it is chipped under 2.5cm, so put your address into the department's zone map before you accept a green-waste line on a quote.

How to choose an arborist in the Perth Hills
A Mundaring block is not a Kalamunda block
Mundaring protects creeklines, native vegetation and habitat trees through Local Planning Scheme No.4, and warns that clearing without approval may be an offence under the Planning and Development Act 2005. Kalamunda's nearest equivalent sits on its revoked list. A crew that works both shires should be able to say which one you are in without looking it up.
The dead one may be the protected one
Mundaring counts a habitat tree as a native tree, dead or alive, with a hollow or substantial trunk diameter, flags 30–50cm as possibly protected under state and federal law for species such as black cockatoos, and maps anything from 80cm up. Say so on the phone if the tree you want gone is a big hollow-bearing stag.
Ask where the timber goes
The borer quarantine's inner zone covers ten named Mundaring localities only, and cuts Pickering Brook and Reservoir east of Ashendon Road out of Kalamunda. Two neighbours on either side of that line get different rules for the same load of wood, so a vague answer about green waste is a real cost risk.
Boots, tyres and dieback
Mundaring reports that a 2020 assessment confirmed Phytophthora dieback in parts of its reserves, that infected soil travels on muddy shoes, vehicles and equipment, and that once soil is infected the disease can be treated but not cured. Ask what a crew does between properties. Chippers and utes move more than woodchip.
Firebreaks are tree work
Both notices are explicit that pruning and felling sit inside the job. Mundaring wants a 3m-wide, 4m-high trafficable strip immediately inside every external boundary, in place before 1 November and held to 31 March; Armadale requires the same dimensions on anything over 5,000m², set no more than 10m in from the boundary, with a 17.5m-radius turning area wherever a break dead-ends, and a penalty of up to $5,000. Book it early.
Registration, and what it actually guarantees
Two things get an arborist registered with Arboriculture Australia: a qualification and a policy. The practising grade turns on an AQF Level 3 in arboriculture and $5 million of public liability as its stated minimum; the consulting grade lifts the qualification to AQF Level 5 and adds $2 million of professional indemnity. Both figures are entry floors for a membership, not a description of what the ute in your driveway is carrying today.
