How to Safely Clear Trees for Bushfire Attack Level Zones

Wollongong sits between the Illawarra escarpment and the Tasman Sea, and much of the city borders bushland, which makes bushfire preparation a practical necessity for many homeowners. Suburbs and localities such as Mount Keira, Mount Ousley, Figtree, Keiraville, Helensburgh, Stanwell Park, Bulli, Russell Vale, Corrimal, Dapto and Haywards Bay all include land mapped as bushfire prone. Clearing trees in these areas requires care, because the work is physically hazardous and is also regulated. This guide explains how Bushfire Attack Level (BAL) ratings work, what tree clearing is permitted, and how to carry out the work safely and legally.

Understanding Bushfire Attack Levels

A Bushfire Attack Level is a measure of a building site's potential exposure to ember attack, radiant heat and direct flame contact. It is determined under Australian Standard AS 3959 (Construction of buildings in bushfire-prone areas) and is used to set construction requirements for new homes, extensions and some renovations. The ratings are:

BAL-LOW: Very low risk, with no special construction requirements. BAL-12.5: Risk of ember attack, with radiant heat up to 12.5 kW/m². BAL-19: Moderate risk from embers and burning debris, with radiant heat up to 19 kW/m². BAL-29: High risk, with increased ember attack and radiant heat up to 29 kW/m². BAL-40: Very high risk, with the likelihood of flame contact and radiant heat up to 40 kW/m². BAL-FZ (Flame Zone): Extreme risk, with direct flame contact and radiant heat above 40 kW/m².

The rating depends on vegetation type, distance from the building to that vegetation, and the slope of the land beneath it. This is why steep, vegetated blocks on the escarpment often receive higher ratings than flat suburban lots. Removing or modifying vegetation can influence a site's assessment, but a BAL rating is not changed https://treeremovalwollongong.com.au/palm-tree-removal/ simply by cutting down a few trees. Any reassessment must be carried out by an accredited bushfire consultant or the relevant authority.

Check the Rules Before Any Tree Is Cut

In New South Wales, the rules for clearing vegetation around homes depend on the property's location, the type of tree and the reason for clearing. Several frameworks may apply in Wollongong, and it is important to confirm which ones before starting.

The 10/50 Vegetation Clearing Code

The NSW Rural Fire Service administers the 10/50 Vegetation Clearing Code of Practice. Where a property falls within a designated 10/50 Vegetation Clearing Entitlement Area, owners of eligible homes may clear:

Trees on their property within 10 metres of the home, without needing approval. Underlying vegetation, such as shrubs and understorey, within 50 metres of the home.

Entitlement depends on the property's location and may exclude certain land, such as areas with threatened ecological communities, Aboriginal heritage sites, or land subject to other restrictions. The RFS website provides an address-based checker, which is the most reliable way to confirm current eligibility. Since arrangements and mapping can be updated, always check the current RFS information rather than relying on older advice.

Wollongong City Council Requirements

Outside the 10/50 entitlement, tree removal in the Wollongong local government area is typically governed by the council's Development Control Plan and tree preservation provisions. Many trees require council permission before they are removed or heavily pruned, particularly on land with environmental protection zoning, in heritage conservation areas, or where the tree is a native species of a certain size. Council officers can advise whether a permit is needed. Penalties for unauthorised clearing can be significant, so it is better to confirm requirements in advance.

Other Approvals and Protections

Additional controls may apply in some circumstances:

Endangered ecological communities and threatened species habitat, which are common on the Illawarra escarpment, are protected under state and federal legislation. Properties adjoining national parks, state forests or the Sydney Catchment Authority's lands may have specific constraints. Strata and community title schemes often require committee approval for tree work. Powerline clearances are managed by Endeavour Energy, and trees near overhead lines should only be worked on by qualified line-clearance arborists.

Planning a Safe Clearing Project

Bushfire-related clearing is more effective when it follows a plan rather than simply removing as many trees as possible. The aim is to reduce fuel and break up the continuity of vegetation between bushland and the building, while keeping the benefits of shade, erosion control and habitat where it is safe to do so.

Assess the Property

Start by walking the property and identifying trees and vegetation within the key distances of the home. Note the following:

Trees overhanging the roof, gutters or chimney. Dead, diseased or structurally unsound trees and large dead limbs. Continuous fuel pathways, such as shrubs touching tree trunks that lead to canopy. Slopes where fire would travel faster uphill toward the house. Accumulations of bark, leaf litter and dead material.

Prioritise Strategic Removal and Pruning

Removing every tree is rarely necessary or recommended. Mature trees can filter embers, reduce wind speed and shield homes from radiant heat. A common strategy includes:

Removing trees that are dead, dying or hazardous. Creating separation between tree canopies so fire cannot easily travel from crown to crown. Pruning lower branches to reduce the chance of a ground fire climbing into the canopy, often called ladder fuel removal. Keeping branches clear of the roof and at least a few metres from chimneys and walls. Replacing highly flammable species close to the home with lower-flammability plants.

Safe Work Practices for Tree Clearing

Tree work is among the most dangerous residential tasks in Australia. Injuries commonly result from falling limbs, chainsaw kickback, unstable ladders, electrical contact and misjudged tree lean. Safety must be built into every stage of the job.

When to Use a Qualified Arborist

Professional help is strongly recommended for any tree that is large, close to structures, near powerlines, on a slope, or in poor condition. Look for an arborist with a recognised qualification, such as AQF Level 3 in Arboriculture, along with current public liability insurance and workers compensation cover. Ask for evidence of both. A reputable operator will also discuss permits, assess the site, and provide a written quote that outlines the scope of work and waste disposal.

Personal Protective Equipment

Anyone carrying out minor pruning or clearing work should wear appropriate protective gear, including:

A helmet with face shield and ear protection. Chainsaw-rated trousers or chaps. Steel-capped, non-slip boots. Safety glasses and gloves. High-visibility clothing.

Chainsaws should only be used by people trained to operate them. Working at height, using climbing equipment or felling large trees should be left to professionals.

Site Safety Steps

Establish an exclusion zone around the work area, at least twice the height of the tree being felled. Check the tree for lean, rot, hollows, cracks, and the weight distribution of its canopy. Identify powerlines, fences, sheds, vehicles and neighbouring properties that could be affected. Plan an escape path at roughly 45 degrees away from the expected fall line. Never work alone, and keep a phone nearby in case of emergency. Avoid cutting during high winds, wet conditions or on days of elevated fire danger.

Timing and Fire Danger Considerations

Chainsaws, slashers, mowers and grinders can all ignite dry vegetation. Do not carry out clearing work on Total Fire Ban days, and be aware that restrictions on hot work and machinery use may apply on days of Extreme or Catastrophic fire danger. Check the NSW RFS website or the Fires Near Me app for current fire danger ratings and total fire ban declarations.

The Illawarra's bushfire season generally runs from spring through summer, although it can start earlier or extend later depending on conditions. Scheduling clearing in late winter or early spring allows time to remove cut material before the peak season begins. Having a fire extinguisher, knapsack sprayer or garden hose available while working is a sensible precaution.

Managing Cut Material

Clearing trees produces a large volume of fuel that can increase risk if left on site. Handle waste carefully:

Do not stack cut timber or green waste against the house, fences or sheds. Chip branches into mulch and spread it thinly, keeping it away from the building and from dense garden beds near the home. Take green waste to a Wollongong City Council waste facility or use a registered green waste service. Store firewood well away from buildings, ideally beyond the immediate asset protection zone.

Pile burning may be restricted or require a permit. Check current RFS rules and council requirements before lighting any fire, and note that hazard reduction burns have specific approval processes.

Environmental and Neighbour Considerations

The escarpment and surrounding bushland support native birds, mammals, reptiles and plant communities, some of which are threatened. Before clearing, inspect trees for nests, hollows and signs of wildlife. Tree hollows are particularly valuable habitat, and disturbing protected species can attract penalties. If wildlife is found, contact a licensed wildlife rescue organisation such as WIRES for advice.

Where a tree sits on or near a boundary, speak with the neighbour before proceeding. Under NSW legislation, disputes about trees that cause damage or danger can be taken to the Land and Environment Court, but early conversation usually prevents conflict. Be aware that you cannot automatically remove a tree that is on neighbouring land, even if it poses a fire risk to your home.

Ongoing Maintenance

Bushfire preparation is not a one-off task. Vegetation regrows, leaf litter accumulates and trees change over time. A seasonal routine helps maintain the protection achieved through clearing:

Clear gutters, roof valleys and decks of leaves and bark regularly. Re-inspect trees each year for deadwood and storm damage. Keep grass short and understorey vegetation trimmed. Review the property plan against updated RFS guidance and any changes to local mapping.

Property owners should also be aware that bushfire mapping and planning provisions are periodically reviewed by state and local authorities. If you are planning building work in 2026 or beyond, confirm the current BAL requirements with a certifier or accredited assessor, as changes to mapping or policy in 2027 and later years may affect your obligations.

Key Takeaways

Safely clearing trees in BAL zones around Wollongong involves understanding your property's bushfire risk, confirming which approvals or entitlements apply, and planning work to reduce fuel without unnecessary environmental loss. Prioritise safety by using qualified arborists for high-risk jobs, wearing proper protective equipment, avoiding work on high fire danger days, and managing cut material responsibly. Check the NSW RFS 10/50 entitlement tool and Wollongong City Council requirements before starting, and maintain your property year-round so that your bushfire protection remains effective.
