Find a Trusted Arborist
in Perth's Northern Suburbs
The kerb decides more here than the tape measure does. The street tree out the front is local government property, and the City of Joondalup treats interfering with one as an offence — damaging, injuring, pruning, removing or killing it. Step across the boundary and almost none of that follows: the same council says there is no specific limit to the height a tree may grow on private property, and the register it keeps of significant trees reaches only land the City owns or manages. Nothing about the size of the thing standing in your back garden starts a council process.
What is on that register still tells you what the corridor grows. Tuart appears on it more often than any other species, including specimens recorded at 31 metres in Craigie and 32 metres in Edgewater. Sycamore Drive in Duncraig carries listed Hill's weeping figs and London planes, and both fig and plane are genera the shot-hole borer breeds in. The suburbs below span three local governments — Stirling at Scarborough, Trigg, Karrinyup and Balcatta, Joondalup across Hillarys and Duncraig, and Wanneroo from Clarkson north to Butler. Crews listed further down cover the corridor; a listing will tell you which of them treats stumps, palms and green waste as part of the job rather than as a second invoice.
Typical arborist pricing in Perth's northern suburbs
Indicative, GST included, and worth reading with the source open. The height bands come from a published Perth cost guide, whose own companion page on Perth arborists reports a different average again and a working floor of $350, well under the $500 its own removal page opens a small job at. The lower figure sets the first cell here, and a single publisher carrying both is the reason nothing on this grid should be read as a rate. The fourth cell is there for a reason: it prices the 20-to-50-metre band, and the trees this corridor's councils have thought worth listing include a 31-metre and a 32-metre tuart. Disposal is the other lever, because the borer quarantine notice restricts what can leave the site at all. An arborist report for a council application sits outside the grid, at $300 to $450 for a single tree.

How to choose an arborist in Perth's northern suburbs
Whose pile is it, once it is on the ground?
Cut a neighbour's overhanging limb back to the fence and you have not acquired it. Joondalup says any branch or root you cut back, and any flower or fruit on it, still belongs to the tree's owner and should be returned; Wanneroo puts it as returned or disposed of with their consent. Settle that before a crew books a tip run you may not be entitled to make.
The reasons the council has already ruled out
Wanneroo's City Tree Policy lists what will not get a City tree removed, and the list is long: views obscured by anything other than a traffic or pedestrian sight line, a disliked variety, dropped leaf, flower, fruit or bark, allergies, shade over a garden or solar panels, a non-essential crossover, a variety that is too large in size other than where it is causing significant damage to infrastructure, and — the one people never expect — that the tree attracts birdlife or other fauna. Unsubstantiated potential damage, if the tree fails or from growth, is ruled out as well.
Blaming the roots is the easy part
Wanneroo's own position on cracked paving and moving footings is that multiple factors usually contribute to foundation movement and it is seldom roots alone, that leaking pipes create an environment encouraging the root growth that then benefits from the moisture, and that it will not remove trees for unfounded claims of damage from tree root activity. Removal is considered only where there is no practical arboricultural solution. An arborist who reaches for the saw before the plumber has looked is skipping a step.
In Wanneroo the wires are the pruning calendar
Wanneroo prunes street trees under power lines annually for community safety and does not prune them to reduce their size, or for any other reason; its policy has Administration or its contractor pruning all City managed trees affected by powerlines on a programmed basis. Behind that sits the state rule: vegetation must be kept at least two metres clear to the side and below the conductors of distribution power lines, and in suburban areas anything rooted inside your property is yours to keep clear, planted or naturally occurring alike.
Ask what is in the spray bottle
A chainsaw is a way for the borer to travel. DPIRD says any tool that comes into contact with infected wood, chainsaws and woodchippers included, should be sanitised before being used on uninfected trees, and names 70% ethanol as the preferred disinfectant. It is the one question on this page a crew can answer in a sentence, and a crew that cannot say what it wipes down with, or at what point in the day, is bringing the last job into your garden.
One word, three registrations
Arborist is a job description, not a licence. Arboriculture Australia says as much when it calls this an unregulated industry, and registers members into three grades instead — practising, consulting, and both at once. Every one of them sits behind $5m of public liability; the two consulting grades add $2m of professional indemnity behind whatever they sign. The qualification is where they part. Climbing and removal work sits at AQF Level 3; anything written down wants the Level 5 diploma. Work out which the job needs before you ring anyone.
