DIY tree removal vs an arborist on the Central Coast - the honest numbers.
We are not going to pretend every tree needs a crew. Plenty of small work is fair DIY and we will tell you so on the phone rather than quote you for it. But the line between “save a few hundred dollars” and “spend six months arguing with an insurer” is narrower and closer to the ground than most people think. Here is exactly where it sits on a Coast block, and what DIY actually costs once the hire and tip fees land.
What you can legally cut yourself
On your own land, small work on an unregulated tree needs no licence. Hand-pruning, hedging, cutting a self-sown sapling, tidying a shrub off the path. Nobody is coming for you and you do not need us.
The first hard limit is legal. Central Coast Council regulates trees above roughly 5m in height or 3m in canopy spread on private land, and pruning or removal beyond minor maintenance needs a permit unless the tree is on the exemption schedule. The schedule is genuinely useful and worth checking before you assume the worst: declared weed species including camphor laurel, privet, willow and cotoneaster are exempt, trees close to an approved dwelling for fire-safety reasons are commonly exempt, and dead trees or trees assessed as imminently dangerous are exempt with an arborist’s assessment. Cutting a regulated tree without a permit carries penalty units that comfortably exceed the price of doing it properly, and the exposure attaches to the land - it follows you to settlement.
The second hard limit is physical, and it is the one that hurts people. DIY stops the moment you are at height, near a conductor, or standing under something with stored energy in it. A leaning trunk, a hung-up limb, a split union - those have tonnes of load waiting to release in a direction you cannot predict from the ground. Ground-level work on a small unregulated tree is fair DIY. A 15m spotted gum over a colorbond fence is not a Saturday.
Powerlines - the zone you cannot enter
This is the one we will not negotiate on. The exclusion zone around live low-voltage powerlines is a minimum of 3m for an untrained person, and no unqualified person may work inside it. That includes a pole saw in your hands and it includes a branch you are dropping that could swing into the zone. Only an accredited Electrical Powerline Clearance operator may work close to the conductors, and for anything near the network mains the correct call is Ausgrid, who manage clearance on their side of the point of attachment.
Every Central Coast summer we get calls from people who have taken an aluminium pole saw up to a limb resting on the service line running into their house. That line is live. From the point of attachment it is your responsibility, not the network’s, which is exactly why people think it is a DIY job. It will kill you. Aluminium conducts, wet spotted gum conducts, and the ground under a Coast block after a wet week conducts beautifully. That job is a phone call, not a Saturday.
What your insurer will actually wear
Read the policy before you start the saw. Home and contents policies typically cover damage from a tree falling on your house from natural causes - the East Coast Low that puts a limb through the roof. They typically exclude damage you cause yourself while carrying out work, particularly where that work needed a licence or a permit you did not have.
Drop a limb through your own roof and you may be arguing for months about whether it was storm damage or your chainsaw. Drop it through the neighbour’s roof and their insurer can come after you personally, and your liability cover may decline if the removal breached the Council’s tree controls. That is the actual downside case, and it is not theoretical - it is why a licensed contractor carries public liability in the first place. When we do the job, the risk sits with our insurer. When you do the job, it sits with you. If a limb has already come down, our insurance claim guide walks through what your insurer will want.
The real cost of a DIY weekend
Here is the arithmetic nobody does before hiring the chainsaw, in 2026 dollars. Chainsaw hire $80 to $140 a day. Chipper hire $180 to $350 a day plus a vehicle that can legally tow it. Green waste to the Central Coast Council waste facilities at $60 to $150 a tonne, and a mid-size gum is several tonnes. PPE you should not skip - chaps, helmet with face and hearing protection, gloves, boots - $150 to $300 if you do not own it. Two full days of your weekend.
Call it $600 to $900 and a very long weekend, before anything goes wrong. And at the end of it you still have a stump you cannot grind without hiring a fourth machine, and possibly a permit you never lodged. The professional quote on the same tree with reasonable access is $1,400 to $3,800 ex-GST, insured, chipped, stump ground and gone in a day. The gap is real. It is also a lot narrower than the headline suggests, and it does not include the value of your weekend or the tail risk of the roof.
Worked example, a job we quoted at Umina Beach last season. Owner planned to take out a 9m camphor laurel himself - exempt species, so no permit needed, and a genuinely reasonable DIY candidate on paper. Hire bill came to $470 for two days including the chipper and the trailer, tip fees $190, and he was three metres up a ladder with a running saw when his neighbour rang us instead. Our quote for the same tree, dropped in sections from a rope, chipped on the street, stump ground to 300mm: $1,650 ex-GST. His real saving was about $990 and a torn shoulder he still has. He took the quote. Sometimes the honest answer is still “do it yourself”, and on a 3m shrub it is. On a 9m tree over a fence it is not.
Four things to check before you hire anyone
If you do hire out, check these four and do not take a website badge as proof. First, AQF Level 3 arboriculture - the working-arborist trade qualification for climbing, pruning and removal. It is the certificate that says the person cutting your tree knows what a branch collar is and why flush cuts kill trees. AQF Level 5 is the consulting tier you engage for AS 4970 tree-protection plans and court-standard reports; see our tree protection page if you are building.
Second, a current public liability certificate of currency, $10m to $20m is standard, with the name on it matching the name on the quote. Third, SafeWork NSW compliance for the equipment in use. Fourth - and this is the fastest filter - make the quote name the standard. A real quote says AS 4373 and describes the cut type. “Prune tree, $900” is not a quote, it is a guess, and the crew that writes it is the crew that tops your gum and leaves you with epicormic regrowth that fails in the next storm.

FAQs - what you can cut, powerlines, insurance, cost, qualifications
What can I legally cut myself?
Small work on unregulated trees on your own land - hand-pruning, hedging, saplings. Council regulates above roughly 5m height or 3m canopy spread, so anything of consequence needs a permit unless it is on the exemption schedule (declared weeds, fire-safety proximity, dead or dangerous with an assessment). Ground-level work on a small unregulated tree is fair DIY. A 15m spotted gum is not.
How close to a powerline can I cut?
You cannot. The exclusion zone around live low-voltage lines is a minimum of 3m for an untrained person and no unqualified person may work inside it. Only an accredited Electrical Powerline Clearance operator works close to conductors, and Ausgrid manages the network side. The service line into your house is live and it is yours - that job is a phone call, not a Saturday.
Will my insurance cover DIY damage?
Often not. Policies typically cover a tree falling on the house from natural causes and exclude damage you cause carrying out work, especially without a required licence or permit. Through the neighbour’s roof, their insurer can come after you personally and your liability cover may decline if the removal was unlawful.
How much do I actually save?
Chainsaw hire $80 to $140/day, chipper $180 to $350/day plus a tow vehicle, tip fees $60 to $150 a tonne, PPE $150 to $300, two days of your weekend. Roughly $600 to $900 before anything goes wrong, with a stump left over. The professional quote with reasonable access is $1,400 to $3,800, insured and gone in a day.
What should I check before hiring an arborist?
AQF Level 3 for the climbing and cutting work (AQF Level 5 is the consulting tier for AS 4970 plans and reports), a current public liability certificate of currency at $10m to $20m with a matching name, SafeWork NSW compliance, and a quote that names AS 4373 and the cut type rather than saying “prune tree, $900”.
