Timber decking for Melbourne & Geelong homes
Australian hardwood decks that handle Melbourne's swing from 40°C afternoons to frosty mornings, detailed properly at the joints where cheap decks fail first.
A timber deck lives or dies at the details you can't see once it's finished: the joist spacing, the fixing type, the ventilation gap under the boards, and the way water is shed away from the house. We build hardwood decks in merbau, spotted gum and blackbutt — species chosen for the way each one behaves in Melbourne's dry-hot, wet-cold cycle rather than because it happened to be on the truck.
Board movement is normal in a natural material; the trick is designing for it. We set consistent gaps, pre-oil boards before laying where it helps, and use hidden or stainless fixings so the surface stays clean and splinter-free for years, not months.
The timbers we work with
Merbau is the workhorse — dense, stable and forgiving, with warm red-brown tones that grey gracefully if you let them. Spotted gum brings stronger grain and a harder wearing surface, ideal where a deck takes furniture and foot traffic daily. Blackbutt sits paler and more even, and carries a bushfire (BAL) rating that matters on Melbourne's fringe and in the hills.
Built for the climate, not the brochure
Bayside decks cop salt-laden air that eats the wrong fixings; inland decks bake and swell on reactive clay. We match fixings (marine-grade stainless near the coast), sub-frame material and coating system to your site — then set the sub-frame off the ground with airflow so the underside dries out instead of rotting quietly.
Finishing and the first year
Oiled hardwood looks best and is easiest to refresh; we'll set you up with the product and a realistic maintenance rhythm rather than promising a deck that never needs attention. Left unoiled, these timbers weather to a silver-grey — a legitimate look, and one we're happy to build toward.

Common questions
How long does a hardwood deck last in Melbourne?
Well-built merbau, spotted gum or blackbutt decks routinely last decades when the sub-frame is ventilated and fixings suit the location. Lifespan is set more by the build and drainage than by the timber alone.
Do I need a permit for a timber deck?
BPC guidance says a structural deck typically requires a building permit. We confirm the exact requirement for your proposed structure with the building surveyor before work starts.
Oiled or left to grey?
Both are valid. Oiling keeps the warm colour and needs periodic recoating; letting it silver is lower-maintenance but changes the look. We'll build to whichever you prefer.
