Do You Need Council Approval to Lop a Tree in Sydney, Australia? A Homeowner’s Guide

In Sydney, where the urban landscape meets iconic bushland and verdant suburbs, trees are a cherished part of the city’s character. However, when a tree becomes a safety hazard, outgrows its space, or interferes with property, the question of removal or pruning—often colloquially called “lopping”—arises. For homeowners, the process is governed by a complex web of regulations, and the short answer, if you speak to any tree lopper or arborist who knows what they are doing is: Yes, you often need council approval, and “lopping” is frequently prohibited outright.

Navigating Sydney’s tree regulations is crucial to avoid hefty fines, which can exceed $10,000 for individuals and $20,000 for companies per offence. This article breaks down the key rules, definitions, and processes you need to understand.

Here’s how council approval works in the Hills District

1. Understanding the Terminology: “Lopping” vs. Pruning

First, it’s critical to understand the language used in regulations, as it dictates what is allowed.

Lopping (or Topping): This refers to the indiscriminate cutting of tree branches to stubs or lateral branches not large enough to assume the terminal role. It is considered harmful, damaging tree health, structure, and aesthetics, and often leads to dangerous regrowth and decay. Most Sydney councils explicitly forbid lopping in their Tree Management or Development Control Plans (DCPs).
Pruning: This is the selective, careful removal of specific branches following the Australian Standard for Pruning of Amenity Trees (AS 4373-2007). Proper pruning is done for health, safety, or clearance and must not compromise the tree’s stability. Even approved pruning often requires consent.

The rule of thumb: If a tree surgeon suggests “lopping,” seek a second opinion from a qualified arborist.

2. The Framework: State, Local, and Overarching Protections

Tree management in Sydney operates on three levels:

A. State-Level Protections: Significant Trees and Biodiversity
Certain trees are protected under State Environmental Planning Policies (SEPPs), like the SEPP (Biodiversity and Conservation) 2021, which protects native vegetation in non-rural areas. Trees listed on the NSW Heritage Register or within a critically endangered ecological community also have stringent protections.

B. Local Environmental Plans (LEPs)
Each council’s LEP may include clauses protecting specific “significant” or “heritage” trees, regardless of location or species. A tree can be listed due to its age, rarity, cultural value, or landscape contribution.

C. Council Tree Preservation Orders (TPOs) and DCPs
This is the most common layer of regulation homeowners encounter. Almost every Sydney council has a TPO within its DCP. These orders typically protect:

All trees above a specified size (e.g., with a trunk height over 3-4 metres, or a trunk circumference/diameter at breast height (DBH) exceeding a certain measurement, often 200mm DBH).
All native tree species, regardless of size, in some councils.
Trees within specific zones, like bushfire prone land, conservation areas, or scenic corridors.

Crucially, these protections apply even to trees on private property. You cannot automatically remove or prune a tree in your backyard just because you own the land.

3. When is Council Approval NOT Required? Common Exemptions

While rules vary, most councils provide exemptions for:

Immediate Danger: If a tree (or part of it) is posing an immediate risk to life or property, you can take action without prior approval. However, you must notify the council as soon as practicable and be prepared to provide evidence (e.g., a report from a Level 5 Qualified Arborist, photos) justifying the emergency.
Dead or Dying Trees: Removal is usually permitted, but councils often require an arborist’s report confirming the tree’s condition.
Invasive Species: Trees listed as noxious weeds (e.g., some species of Willow, Privet, Bamboo) can often be removed without approval.
Small Trees/Shrubs: Species below the prescribed size limits in your council’s DCP.
Approved Development: Trees approved for removal as part of a valid Development Application (DA) or Complying Development Certificate (CDC).
