Hardwood Decking

It is important you choose an option that is suited to your unique style, climate, and lifestyle – and this guide will help you make your decision with confidence.

Not only does Merbau have a beautiful appearance, it is also perfect for hot climates and fire-prone areas. It has the highest rating for resistance against fungi and insects – making it a very popular hardwood decking option in WA. The disadvantage of Merbau is that tannins within the wood need to be managed as part of the overall installation process. This is easily achieved with a good tannin blocker (a water-based sealer).


Ironbark is a eucalyptus wood known for its strength and durability. It has stood the test of time for hundreds of years – extensively used in heavy construction. This can also be a disadvantage as it can be difficult to work with due to the density of the wood fibre. However, if you are aiming for a uniquely weathered look, this can be achieved easily by allowing the boards to grey-off naturally. A virtually no maintenance option.

Spotted Gum

This timber is perfect if you’re looking for an eco-friendly option, as it is plantation grown to ensure long term integrity of the forest’s biodiversity. It has a beautiful appearance, with a wavy grain and vibrant colour. Not only that, but Spotted Gum is also long lasting and fire-resistant. The downside to using spotted gum is that it can be prone to moisture and mould – so regular maintenance is essential.


Beautiful in colour and easy to work with – Jarrah is a popular hardwood decking choice across WA. It is strong and durable and naturally resistant to insects. While Jarrah adds warm, mahogany colours that compliment the WA landscape – these colours can bleach if it is exposed to harsh sunlight. To maintain integrity of the timber (wide boards especially), good ventilation as part of the decking design is critical.


A mixture of wood fibres and plastics, Composite is great if you’re looking for a low maintenance option. At WA Timber Decking Professionals, we recommend Duralife, Modwood, Traxion and Newtechwood. These are strong, reliable, and resistant to mould and mildew. The downside is that these timbers don’t possess the unique grain, colours, and patterns that you can only get from pure wood. Furthermore, some imported brands of composite tend to become very hot when exposed to the sun. Good research is recommended when choosing a composite product.
