Type of Decking Timber

Australia offers a variety of timber decking choices, choosing the type of timber comes down to personal taste and budget. Hardwoods are more durable, highly resilient and quality options. Available in a range of colours with a stunning look and feel.

There are number of hardwood timbers to choose from. Our ASNU Painters can annually oil or re-stain your deck to ensure your hardwood deck remains in top condition for many years.

Treated Pine

Treated Pine is a popular decking choice as it is versatile and cheaper than hardwoods. Plus, Treated Pine absorbs stain or paint well so gives a nice finish. It requires oiling annually for long-lasting results. Not all treated pine is suitable for decking though. However, our deck builder will ensure your treated pine adheres to all the required safety and hazard standards.

Treated Pine


Jarrah it is a very popular choice for Australian decks. It is highly durability and fire-resistant. Jarrah comes in a range of stunning colours ranging from light to very dark browns and reds that give a stunning finish.  Jarrah is more expensive than other timbers.



Blackbutt is native to Australia and is highly fire-resistant. It is a pale brown colour that compliments most homes and environments.

Blackbutt needs to be sealed as soon as possible to prevent cracking. However, it can be stained for a different look.

Spotted Gum

Spotted Gum is also a good fire-resistant timber.  It is quite a dense timber that shrinks less than other timbers. And it comes in a range of browns, from pale to chocolate brown.

Spotted Gum


Merbau is a less expensive but popular option because it is durable, rot and insect resistant. However, Merbau is not native to Australia and usually comes from Southeast Asian rainforests. For a little extra money sustainably, harvested Merbau is available.



Because it is such a dense heavy hardwood, Ironbark has the highest durability rating. However, Ironbark is harder to work with it, but the final finish is worth it.  Ironbark comes in a range of beautiful natural colours ranging from pale brown to deep red. Plus Ironbark is highly fire, termite and rot resistant making it a wonderful choice around pools.
