Certified arborists audit your street and park trees and deliver register-ready data your asset team can import and act on. Built for council tree and open space teams across Sydney, as part of our tree services for councils. Request an audit quote to start a scoping discussion.
A reliable street tree register gives councils a current, defensible record of every tree they manage. Without one, risk exposure is guesswork and the duty of care is hard to demonstrate.
Records that are incomplete or years old make it difficult to say which trees are healthy, which are declining and which need attention first.
When councils assess tree works, they lean on three things: the condition of the tree (disease, decay, structural defects, declining health), the constraints of the site (buildings, utilities, infrastructure) and recommendations from a qualified arborist. They also check whether pruning, crown reduction or root management could solve the problem before tree removal is considered.
A register that captures this information makes each decision easier to justify and easier to explain to residents.
Good tree asset management starts with accurate records that show where the risk sits across street and park trees, so works can be ranked and funded with evidence. Councils also weigh the cost of proposed works against a tree’s ecological and aesthetic value to the community.
A register that teams keep current gives asset and open space teams the facts to make that call, rather than reacting after a branch drops or a complaint arrives.
A council tree audit records a consistent set of fields for each tree so the asset register stays comparable across streets, parks, reserves and verges. Each entry includes species, height, canopy spread and trunk diameter, plus a location reference that ties back to your existing records.
Each tree receives a tree condition assessment covering disease, decay, structural defects and declining health. These are the same factors council officers weigh when assessing tree works. A risk rating is assigned, with site constraints noted alongside it: buildings, utilities, kerbs, footpaths and other infrastructure.
A register is only useful if every entry tells the next officer what the tree is doing and what’s around it. Condition without context leaves gaps.

Each record closes with the practical outcome. Notes cover pruning or root management options, whether alternatives to removal are realistic, and a priority level so works can be sequenced. Where a tree is flagged for removal, the record is written to support the permit and approval pathway.
A tree audit runs in four stages: scoping, field inspection, quality checks and handover. It starts with a scoping discussion where the council officer outlines the streets or parks, approximate tree numbers, the data fields needed and the preferred file format.
Trees Down Under confirms the approach and a work plan, so the client’s input concentrates at the front of the project.
AQF Level 3-5 certified arborists walk each site and complete street tree data collection against the agreed fields. Entries are then checked for gaps, duplicate IDs and inconsistent ratings before anything leaves the office.
Records are supplied in the format agreed at scoping, ready to import into existing council tree management systems or tree asset register software. The client reviews the file and raises any queries, without needing to supervise fieldwork or reformat data.
Audit data is only as useful as the people who collect it. Trees Down Under has operated since 2005, with over 20 years of hands-on arboriculture and knowledge carried across two generations of the family business.
Every audit is completed by a certified arborist holding AQF Level 3-5 qualifications, so species identification, condition ratings and risk ratings come from trained assessors rather than general field staff. This is arboricultural asset management done by the people who will also be on site if works follow.
The business is based in Dural and has worked on street and park trees across the Hills District and wider Sydney for two decades. That local familiarity with soils, species and council expectations helps the team record data in a way that suits Sydney councils.
Reviews are public and verifiable. Trees Down Under holds a 4.8/5 Google rating from more than 182 verified reviews, which gives asset and open space officers an independent view of how the work is delivered.
Records built on that experience feed straight into a long-term urban forest inventory and municipal tree inventory, ready for the maintenance planning that follows.
Each risk rating and condition note in the audit becomes a scheduled action, so tree maintenance scheduling follows the data rather than guesswork. Large canopy trees go on an annual inspection cycle, and pruning is planned every 12 to 24 months depending on growth rate and risk.
Street and park trees near shops, schools, car parks and driveways are flagged for more frequent checks. Falling limbs and lifting roots carry greater consequences where people and vehicles move daily.
Certified arborists can build a maintenance schedule around species, age and surrounding environment. Where an audit points to tree pruning Sydney works, the same records support the council’s own approvals and budgeting.
Street and park trees should be re-audited every 12 to 18 months for routine work, and sooner when warning signs appear. Cracked or leaning trunks, dead or hanging limbs, roots lifting pavements and branches growing over roofs or power lines all justify an earlier visit.
Each re-audit updates the asset register, so it stays a risk-ranked works program rather than a static record. Catching defects early is far cheaper than responding after a failure.
The same crew that audits can carry out the removals and pruning the register identifies, including crane-assisted work on large or difficult-access trees. Green waste disposal and site clean-up are included in every quote, so officers are not coordinating a second contractor.
Audit records and arborist reports give council officers the evidence to weigh tree removal against alternatives such as pruning, crown reduction or root management. Trees Down Under keeps the cost side just as clear: inspections are free with no call-out fee, and quotes are itemised so there are no hidden extras.
Where a tree is approved for removal, the crane is our own, so there is no separate crane fee. Same-day quoting is offered, though timing depends on the job. For a sense of pricing before you ask, see our guide to tree removal cost Sydney.
Trees can fail between inspection cycles, and storms often trigger those failures. Emergency response runs 24/7 across all Sydney regions, so a tree that is dead, dangerous or blocking a road can be made safe without waiting for the next scheduled visit. Call 0475 463 597 at any hour.
Before any tree is removed, council permit requirements should be checked. Dead or dangerous trees may be exempt, but the rules differ by area. Blacktown City Council, for example, publishes its Tree Preservation Order online, and The Hills Shire Council and Parramatta City Council set out their own tree management rules on their websites.
Replacement trees should be native species suited to local soil and climate, matched to the space and their mature size. Plant in the cooler months, May to August, and keep them well clear of power lines and structures.
Trees Down Under works with councils and public agencies across Sydney on a full program of street, park and reserve tree work. Explore our related council services below.
Once the audit is done, the follow-on work can sit with the same certified team. Each service below is handled by AQF Level 3-5 arborists, with Cm3 certification, full insurance and our own crane fleet.
