The right decking timber isn't just about looks — it's about lasting through Australian sun, rain and everything in between.
Compare Australia's top decking timbers and choose the right option for your home and climate.
An outdoor deck is one of the most valuable additions you can make to your home. Whether you're creating a space for entertaining, relaxing with family, or increasing your property's value, choosing the right decking timber is one of the most important decisions you'll make.
Australia's climate can be harsh, with intense sun, heavy rain, humidity, and changing temperatures. Selecting a durable timber that can withstand these conditions ensures your deck remains beautiful and functional for many years.
In this guide, we'll compare the most popular decking timbers in Australia and help you choose the best option for your lifestyle and budget.
Outdoor decking is exposed to weather every day. The right timber offers:
Investing in quality materials from the beginning often reduces maintenance and replacement costs in the future.

Spotted Gum is one of Australia's highest-quality native hardwoods.
Its distinctive grain makes every deck unique.

Blackbutt is becoming increasingly popular because of its lighter colour and contemporary appearance.
Blackbutt complements modern Australian architecture beautifully.

Jarrah is well known for its deep red tones and outstanding durability.

Proper maintenance extends the life of your deck.
Sweep away leaves and dirt to prevent moisture build-up and mould.
