Dealing with a problem tree is stressful enough without discovering (too late!) that removing it without approval carries a serious fine. A large gum tree dropping limbs on your roof, a pine lifting the driveway, roots undermining a retaining wall. The instinct is to generally get it sorted quickly, but in Adelaide, tree removal is regulated under South Australian planning law, and the consequences of getting it wrong can far outweigh the cost of doing it right the first time.
This guide covers what you need to know before you act.
Trees in Adelaide are protected based on size, not age or species alone. Under the Planning, Development and Infrastructure Act 2016 (SA) and the associated Planning and Design Code, the SA Government defines two categories of protected tree:
Both categories are protected and cannot be removed or heavily pruned without approval.
If your tree meets either threshold, you’ll need to lodge a development application through your local council. While applications are managed locally, the rules are set at state level so the process is broadly consistent across Adelaide.
Approval isn’t granted simply because a tree is inconvenient and in most cases, you’ll need to demonstrate that the tree is structurally unsafe, diseased or dying or actively causing damage to buildings, foundations or infrastructure.
This is where a professional arborist report becomes essential as councils require technical evidence to support an application, and a thorough assessment from a qualified arborist is typically the deciding factor in whether an application succeeds.
There are exemptions but this is where many Adelaide homeowners run into trouble.
A tree within 10 metres of a dwelling or in-ground swimming pool may be exempt from the approval process. However, this exemption does not apply across all species. Many native trees, including certain Eucalyptus species, remain protected regardless of proximity. Zoning and overlays can also affect whether the exemption applies to your property.
This is one of the most commonly misunderstood aspects of tree law in Adelaide. We regularly hear from homeowners who assumed the 10-metre rule covered their situation — and found out otherwise after the fact. Always verify before proceeding.
A tree that is completely dead can generally be removed without approval, given the safety risk it poses, although councils may still require evidence that the tree is dead rather than simply dormant which isn’t always obvious to an untrained eye.
Some trees classified as environmental weeds or declared pest species can be removed without a permit. Each council maintains its own list, so it’s worth confirming your tree’s status before taking any action.
Even with approval, conditions often apply. To protect Adelaide’s urban canopy, councils frequently require:
Where the property can’t accommodate new plantings, a contribution to the council’s tree fund may be required instead.
Some homeowners attempt removal themselves to sidestep the process. Beyond the physical dangers of working at height with heavy equipment, the legal exposure is significant.
Unauthorised removal of a protected tree can result in fines running into the tens of thousands of dollars, along with formal enforcement action from council. In our experience, the cost of getting caught (both financially and in terms of time) consistently exceeds what proper approval and professional removal would have cost.
The work itself carries real risks with the potential of structural failure during removal, damage to fences, roofing, vehicles and neighbouring properties. These aren’t edge cases and they happen when tree removal is approached without the right training and equipment.
Start with these basics before making any decisions:
If the circumference exceeds 2 metres at 1 metre above ground, it’s likely regulated.
Some trees carry additional protections regardless of size.
Don’t assume the 10 metre rule applies to your situation.
This is the step that most often saves people from costly mistakes.
Navigating council requirements, preparing a compliant arborist report and carrying out safe removal… this is work that benefits from experience and at Adelaide Arborists we can provide detailed reports for council applications, handle tree removal to the required standard and know how local councils assess these applications. If you’re unsure about your tree, contact us before you make any decisions and we’ll give you a clear, honest assessment of where you stand and what your options are.
