In the Blue Mountains, almost every property sits beside bushland, and many sit within heritage gardens planted generations ago. That mix of bushfire risk, steep sandstone country and much-loved trees makes independent tree advice essential. Synertree provides arborist reports, Arboricultural Impact Assessments (AIAs) and tree risk assessments from the foothills to Mount Victoria. Arborist reports and AIAs start from $880 + GST (AIAs for one tree), with fixed quotations within 24 hours.
Arborist reports from $880 + GST · AIAs from $880 + GST for one tree · Fixed quotations within 24 hours · All reports are completed by an AQF Level 5 or AQF Level 8 Arborist
What's included in an AIA from $880 + GST (one tree): a basic development proposal. We supply our captured tree data to your architect and landscape architect, and their plans show the tree retention and removal plan. ArborCAD Tree Protection Plans aren't included. ArborCAD Tree Protection Plans and larger or complex sites are quoted separately on your plans, with a fixed quotation within 24 hours.
Lower Mountains and foothills: Emu Plains, Emu Heights, Leonay, Lapstone, Glenbrook, Blaxland, Mount Riverview, Warrimoo, Sun Valley, Valley Heights, Springwood, Winmalee, Yellow Rock, Faulconbridge.
Mid Mountains: Linden, Woodford, Hazelbrook, Lawson, Bullaburra.
Upper Mountains: Wentworth Falls, Leura, Katoomba, Medlow Bath, Blackheath, Mount Victoria, Mount Wilson and the surrounding villages.
We work across the following council areas:
Our AIAs and arborist reports are prepared to suit each council's DA tree requirements, and to AS 4970:2025.
Bushfire-prone land. Most Mountains properties are on bushfire-prone land, where asset protection requirements affect which trees stay and which go. Our reports give designers and bushfire consultants the tree information they need, including health, structure, retention value and risk, so that tree retention and bushfire protection can be balanced on evidence rather than assumption.
Heritage gardens and cold-climate trees. The upper Mountains are known for historic gardens with mature exotic trees: conifers, oaks, maples, beeches and elms, many planted a century or more ago. These trees can be significant in the streetscape and the garden's history. Our reports set out their condition and significance clearly, which helps heritage advisers, planners and owners reach a sensible outcome.
Storm, snow and wind damage. Ridge-top villages see strong westerly winds and occasional snow loading. Tall eucalypts and large conifers can lose limbs or fail in storms. A QTRA or ISA TRAQ tree risk assessment gives you an objective measure of risk, so you can act on the trees that need it and keep the ones that don't.
Sandstone and shallow soils. Much of the Mountains sits on sandstone with shallow, sandy soils, where roots run along rock joints and close to the surface. Excavation for additions, garages and driveways can affect roots in ways a desktop calculation won't show. Non-destructive AirSpade investigation and LiDAR 3D root mapping show where the roots are.
Bushland edges and sensitive vegetation. Properties border national park, reserves, creek lines and hanging swamps. Remnant trees such as Blue Mountains Ash, Sydney Peppermint and Scribbly Gums often have high retention value and may provide habitat. Where a site may also need ecological input, we'll flag it at the start.
Foothill river flats. At the foot of the Mountains, larger lots on deeper river soils carry big Cabbage Gums, Forest Red Gums and River Oaks. New homes, sheds and pools on these blocks need careful Tree Protection Zone planning to AS 4970:2025.
Q: Do you work in the Blue Mountains City Council area?
A: Yes. We work right across the Blue Mountains City Council area and the Penrith City Council foothills, with reports prepared to suit each council's DA tree requirements.
Q: My property is bushfire-prone. Will my trees have to go?
A: Not necessarily. We provide the tree information your bushfire consultant and designer need, so they can decide which trees can stay and which can't.
Q: Is the big old conifer in my garden safe after the last storm?
A: A QTRA or ISA TRAQ risk assessment will give you an independent answer, along with practical recommendations.
Q: How much does an arborist report cost in the Blue Mountains?
A: Arborist reports start from $880 + GST for 1–5 trees. AIAs start from $880 + GST for one tree on a basic development proposal. ArborCAD Tree Protection Plans and larger or complex sites are quoted separately on your plans, with a fixed quotation within 24 hours.
