TPAA - Timber Preservers Association of Australia

The Timber Preservers’ Association of Australia (TPAA) represents the nation's wood preservation industry. It is made up of timber treaters, preservative suppliers, research organisations, and individuals and bodies having an interest in the production and use of preservative-treated timber.

The TPAA promotes a knowledge of the principles and methods of timber preservation within the industry, helps with establishing and adhering to Standards for the treatment of timber, and promotes best practice in the production of treated wood.

The TPAA encourages its members to comply with national Standards and applicable legislation, to use sound and responsible environmental procedures, and to produce fit-for-purpose treated timber products.

Whilst the TPAA maintains a list of timber treatment plants, it does not 'register' treatment plants and relies on members to produce fit-for-purpose treated timber products.

TPAA members produce a range of treated timber products to suit all uses, from heavy industrial applications to treated products for the house and garden.


The TPAA covers a wide range of capabilities relating to wood preservation, including:
Treatment process technologies

Treating chemical formulation composition and specifications

Advice on test processes for new products
Knowledge of where and when to use treated timber

How to handle treated products

How to safely dispose of waste material form treated timber and spent treated timber at the end of its life
