Queensland kauri pine

Agathis robusta · also called Kauri pine, Queensland kauri, South Queensland kauri

The Queensland kauri pine is a tall native conifer with a smooth trunk and broad, leathery leaves rather than needles. Its natural range takes in the Wide Bay district of south-east Queensland and the rainforests of the north. Brisbane City Council plants this kauri pine as a street tree on wide verges, where it grows 15 to 25 metres tall, so it suits big blocks and parks rather than small yards.

How to identify a Queensland kauri pine

A tall conifer, 15 to 25 metres in Brisbane streets, with a smooth trunk and no buttresses at the base. The bark is orange-brown, brown or grey and sheds in broad scales or scattered flakes. Its leaves look nothing like pine needles: they are flat, thick and leathery, 5 to 13 cm long, with fine veins running lengthwise. The female cones are round and 9 to 15 cm long, while the smaller, finger-shaped male cones, 4 to 8.5 cm long, often litter the ground under mature trees.

Growing a Queensland kauri pine in Brisbane

Brisbane City Council lists Queensland kauri pine as a street tree for its higher land and arterial road precincts, but only on verges wider than 5 metres and not under power lines. That tells you how much space it needs. It is native to Queensland, typically a tree of drier rainforest, and its southern population grows in the Wide Bay district, including K'gari, rather than around Brisbane itself. Plant it only where a 15 to 25 metre tree has room.

What to watch out for

This is a very large tree: 15 to 25 metres in Brisbane streets and up to 50 metres in the wild, so think about its full size before planting near the house, fences or services. Mature trees shed male cones 4 to 8.5 cm long that collect under the canopy.

  • Falling cones. Mature trees shed male cones 4 to 8.5 cm long, which build up on the ground under the canopy.
  • Size. It reaches 15 to 25 m in Brisbane streets and up to 50 m in the wild, so it needs a lot of room.

Pruning and care

Kauri pines need little pruning. Leave the natural shape and single leader alone, and remove only dead branches or low limbs that block paths, driveways or sight lines. Water young trees through dry spells until they are established. Rake up fallen cones and leaves where they collect on paths or lawns. Because mature trees are so tall, any work in the upper canopy is a job for a qualified arborist with climbing or elevated work gear.
