QLD Timber Species 

Most of Queensland’s timber is sourced from our mature softwood plantations which are dominated by exotic pine and native hoop pine. However, Queensland has a young and expanding hardwood estate which is likely to start producing timber post 2020.

Native hardwood forests provide timber that is very dense, strong and extremely durable in exposed use. The most significant commercial native hardwood species in Queensland include:

Native Cypress also grows in some of the more isolated areas of Queensland west of the Great Dividing range.

Cypress has a natural resistance to termites which makes it popular for structural applications such as house framing, flooring, wall lining, fencing and cladding.

This table outlines Queensland’s timber species plus you can check out what timber species are permitted under Queensland Building Regulations for specific purposes in the book  Construction Timbers in Queensland.
