Hardwood Decking in Australia

Thinking about building a deck or enhancing your outdoor space? If you're looking for hardwood decking in Australia, this guide breaks down key things you should know so you can pick the right timber that lasts, looks great, and withstands local weather.

Why Choose Hardwood Decking?

Naturally strong and durable — hardwoods like Blackbutt, Spotted Gum, Merbau, and Jarrah are built to last, making them ideal for outdoor decks.

Resistant to wear, rot and insects — quality hardwoods offer excellent resilience and performance in Australian conditions.

Aesthetic appeal — hardwoods typically offer rich natural tones, warm grain patterns and a premium finish that blends beautifully with outdoor spaces.

Sustainable options — many hardwood decking sources work with responsibly managed forests, meaning you can choose materials that are both strong and eco-friendly.

What to Look for When Buying Hardwood Decking:

Durability rating – Check the durability class or rating; higher classes mean better resistance above ground.

Fire rating – In bushfire-prone areas, go for timber species or grades rated for BAL (Bushfire Attack Level).

Moisture content & drying – Kiln-dried boards help reduce shrinkage, warping or splitting once installed.

Board dimensions – Thickness and width matter for both load capacity and the finished look; thicker boards are stronger.

Fasteners and installation – Use stainless steel screws or hidden-fix systems, and pre-drill for dense hardwoods to prevent splitting.

Maintenance – Plan to oil or seal your decking regularly to keep its colour and protect it from weathering.

Environmental certification – Look for FSC or PEFC certification, or other proof that the timber has been sourced sustainably.

Popular Hardwood Species Used in Australian Decking:

Blackbutt — known for its fire resistance and balanced colour

Spotted Gum — very dense, highly durable, beautiful grain

Merbau — rich reddish-brown tones, strong structural performance

Jarrah — deep red tones, very hard and weather resistant

If done right, hardwood decking doesn’t just improve your outdoor look — it pays off in value, longevity, and low-maintenance performance.
