Do you need a permit?

Illawarra Flame Tree is a protected tree in effectively every council Pro Climbing Tree Services covers. Expect to need a tree permit, or a development application where the property is heritage listed or in a heritage conservation area.

How to identify it

Unmistakable in summer when the tree drops its leaves and covers itself in brilliant scarlet bell flowers. Leaves are glossy and variably lobed. Boat shaped woody seed pods contain irritating yellow hairs around the seeds.

Where it grows in Sydney

Widely planted as a feature tree across the Northern Beaches, North Shore, Inner West and Eastern Suburbs, and occasionally naturally occurring in warm sheltered gullies.

Common problems

  • Very large at maturity for the gardens it is planted in
  • Seed pod hairs irritate skin and eyes
  • Flower and leaf drop in large volumes
  • Fleshy roots damage nearby paving

What removal involves

Worth checking the council before quoting, because status varies. It is on the Northern Beaches exempt species list, which is unusual for a native, while in every other council on this list it is treated as a protected tree subject to the size thresholds.

Council permit rules, council by council

Status below is for a tree on private land that has passed the council's size threshold. Heritage items, heritage conservation areas, significant tree registers, biodiversity mapping and conditions of development consent override every exemption shown here.

Frequently asked questions

Is the Illawarra Flame Tree really exempt on the Northern Beaches?

Yes. It appears on the Northern Beaches exempt tree species list, so it can be removed without consent unless it is a heritage item or within a heritage conservation area. That exemption does not carry to other councils.

Important note on council rules

This encyclopedia is a practical guide for Sydney property owners, not legal advice. Council tree rules change, and exemptions are frequently overridden by heritage listings, heritage conservation areas, significant tree registers, biodiversity mapping, endangered ecological communities and conditions attached to development consent. Always confirm the current rules with your council for your specific address before any tree work begins, or ask us to check it for you.
