Tree Supply
Support
From early-stage planning to contract growing, delivery, planting and aftercare, we offer expert advice and proven reliability to ensure your planting project’s success – on time and to the highest standard.
Contract Supply
Developers and designers increasingly realise that securing large trees early—well before planting—is essential. Leaving tree supply to the last minute or bundling it with civil or landscape contracts often results in poor selection, delays, and compromised quality.
Key points:
Take ownership: Don’t delegate responsibility for key trees—work directly with a trusted grower.
Plan ahead: Large trees take years to grow. Secure them early under a grow-on contract, separate from general plant supply.
Set high standards: Specify to AS 2303:2018—the most rigorous tree standard in Australia, if not globally.
Choose quality over price: Great trees come from skilled growers, not shortcuts.
Trees Impact has a proven track record of supplying high-quality trees for major Australian projects.
General Supply
At Trees Impact, we specialise in larger trees—typically in the 200 to 700 litre range—where our expertise and reputation are strongest. These semi-mature trees usually stand between 3 and 10 metres tall, depending on species. While our core focus is on this size range, we can also supply selected smaller stock and, in special cases, bigger trees - up to 3000 litres.
Natives
A large part of our production is devoted to Australian natives in sizes not otherwise available in the general market. Trees commonly in production include Angophora, Araucaria, Banksia, Cupaniopsis, Eucalyptus/Corymbia, Ficus, Lophostemon, Syncarpia, Tristaniopsis, and Waterhousia.
Exotics
A smaller range of exotics commonly in production includes Fraxinus, Jacaranda, Lagerstroemia, Ulmus, and Zelkova.
Servicing Eastern Australia
Deliveries between Brisbane and Melbourne are routine, with regular shipments to Townsville, Adelaide, and inland NSW. Trees are carefully prepared, packed, and covered for transport. Our carriers’ vehicles have cranes for loading and unloading, and only experienced drivers handle our trees.
“I would like to thank you all at Trees Impact for the great relationship and excellent trees! And thanks for the technical advice that has been readily provided when I have needed it.”

We specialise in larger trees, typically in the 200 to 800 litre range, grown to the highest standard and warranted to meet the requirements of Australian Standard AS 2303:2018. These semi-mature trees usually stand between 3 and 10 metres tall, depending on species.
While our core focus is on this size range, we can also supply selected smaller stock and, in special cases, bigger trees up to 2000 litres.

Trees Impact created the ‘NATSPEC Specification for Landscape Trees’, which has now evolved into Australian Standard AS 2303:2018. We pioneered production methods to consistently meet the world’s most rigorous standard – now accepted as the Australian benchmark.
Before leaving the nursery, our trees all undergo a comprehensive pre-delivery quality check. The checks ensure AS 2303:2018 compliance – as a matter of course and without extra charge.
-
AS 2303:2018 is the Australian Standard for tree stock for landscape use - the most rigorous tree specification in Australia, if not globally.
It ensures trees have:
Proper root structure and development
Sound trunk and branch structure
Appropriate balance between above-ground and below-ground parts
Self-supporting stems without the need for permanent staking
Freedom from structural defects that could cause future failure
For public spaces, this matters even more: Organisations managing tree plantings in public spaces have a duty of care to ensure trees are stable and safe. Conformance to AS 2303:2018 is an important factor when acquiring these trees, as it helps mitigate risks associated with structural failures that could endanger people or property.
Trees Impact pioneered this standard - our co-founder Ross Clark authored the original NATSPEC specification that evolved into AS 2303:2018.
-
We propagate most trees ourselves from seed or cutting, growing them for an average of 2-3 years before they reach saleable maturity (averaging around 300 litres).
Our nursery practices are designed around the production of trees that reliably conform to AS 2303:2018 and include:
Root management: Sequential root pruning at each stage to ensure radial root development
Wide spacing: Each tree grown in its own space without crowding
Minimal staking: Trees develop naturally to be self-supporting
Expert pruning: Formative pruning throughout production for strong structure
Above-ground containers: All trees grown in containers, not in-ground
-
Deliveries to all areas between Brisbane and Melbourne are routine, with loads as far afield as Townsville in far north Queensland, Adelaide in South Australia and the inland regions of New South Wales not uncommon. Trees are specially prepared, packed and covered for transport.
-
Vehicles are equipped with cranes for loading/unloading, and only drivers experienced in handling our product are used.
-
Yes. This is very common.
When placing an order for trees to be supplied at a future time, it is important that customers carefully consider the date when they realistically expect the plants will be needed for planting. A number of decisions are based on that ‘nominated date’ and a number of outcomes depend on the accuracy or otherwise of that date.

-
Yes. This is very common.
If delivery of the trees is deferred for more than a month, fees for continuing to hold them may become payable until delivery. If the delay continues for longer periods, the trees may need to be potted on to bigger sizes and their price increased accordingly.
