Hardwood decking for Sydney projects
Sydney Timber Supply supplies hardwood decking to Sydney builders, landscapers and homeowners from our base at 12 Dyer Crescent, West Gosford NSW. The range runs from supplier-documented Class 1 Australian hardwoods through to Class 2 Merbau and Peninsula Blonde, all sold per linear metre with the rate shown on every product page, so you can price your deck yourself and add your metres to the cart.

How buying works
Hardwood decking is priced per linear metre and supplied in random lengths. The linear metre rate is shown on each product page, so most orders can go straight through the cart:
- Measure your deck area and convert it to linear metres with the timber calculator. The calculator guide shows the working if you want to check it by hand.
- Add your linear metres to the cart and check out, or request a quote if you need pack quantities, preferred lengths or trade volumes. Preferred lengths are confirmed against current supplier availability.
- Builders and repeat buyers can apply for a trade account, and larger jobs are handled through bulk and pallet orders.
Delivery to Sydney
We deliver to Sydney from West Gosford. Delivery is quoted per order based on load size, board length and site access, because long boards need the right vehicle and difficult access changes how an order is delivered. Include your postcode and quantities in your quote request for delivered pricing, or see delivery and pickup for how quoting works. Pickup from West Gosford is also available if you would rather collect.
Why buy from a supply-backed supplier?
Decking orders are rarely simple: mixed lengths, a specific profile, a delivery window, a site with tricky access. Standard quantities are priced online so you can order without waiting, and anything unusual goes through a quote, where a person checks your quantities and lengths against current supplier availability before you commit. It also means honest numbers: we publish supplier-documented specifications, and where a value is not published we say so rather than fill the gap.
