On the Gold Coast in 2026, hardwood timber decking costs $350-$550 per square metre supplied and installed, and composite decking $450-$700. The guide arithmetic for 20 m² is $7,000-$11,000 in timber or $9,000-$14,000 in composite.

Overview
Decking is one of the highest-value additions you can make to a Gold Coast home, and also one of the easiest to under-budget. The board price you see advertised is only part of it - the substructure, footings, height, stairs, balustrades and approvals often make up more of the final figure than the decking surface itself. This guide sets out real 2026 Gold Coast decking prices, the difference between timber and composite over the life of the deck, and what pushes a quote up. Every deck we build is quoted fixed price after a site measure and level check.

Timber versus composite cost per square metre
Australian hardwood decking such as spotted gum, blackbutt or merbau runs $350-$550 per square metre supplied and installed on a standard low-level substructure. Composite decking sits at $450-$700 per square metre installed. Compare actual product care requirements alongside the initial quote. No fixed long-term saving is promised; exposure, cleaning, coatings and replacement needs vary.
Ground-level, elevated and multi-level decks
A ground-level 20 square metre timber deck generally lands between $7,000 and $11,000, and the same deck in composite $9,000-$14,000. Elevated decks need site-specific structural and barrier checks; we quote the actual design rather than assuming a fixed additional price. Multi-level decks stepping down a slope in Highland Park, Tallai or Bonogin are quoted individually because the substructure carries most of the cost.
Stairs, balustrades, screens and extras
Stairs, balustrades, screening, drainage and roofs are itemised for the actual design, materials and access. Demolition, disposal, preparation, engineering and certification are confirmed in the written quote, not assumed to be included in the guide rate.
Approvals and compliance on the Gold Coast
Approval depends on height, area, design, roof, attachment, boundaries, overlays and pool-barrier effects. A deck below one metre is not automatically exempt. A private building certifier confirms the applicable requirements, including structural design and barriers. The quote identifies responsibility for engineering, certification and fees.
Coastal conditions and material choice
Salt exposure in suburbs like Palm Beach, Bilinga, Mermaid Beach and Jacobs Well corrodes standard fixings quickly, so we specify stainless or hot-dip galvanised hardware as standard near the water. In shaded, high-rainfall pockets such as Currumbin Valley and Tallebudgera, timber decks decay faster and need more frequent inspection of bearers and joists - which is why timber repair work is so common in those areas.

Frequently asked questions
How much does decking cost per square metre on the Gold Coast?
Hardwood timber decking costs $350-$550 per square metre supplied and installed in 2026, and composite decking $450-$700 per square metre.
How much does a 20sqm deck cost?
A ground-level 20 square metre timber deck typically costs $7,000-$11,000, and the same deck in composite $9,000-$14,000.
Is composite decking cheaper than timber overall?
Compare upfront quotes and the selected products’ maintenance requirements. Lifetime costs depend on exposure and care; we do not guarantee a saving.
Do I need council approval for a deck on the Gold Coast?
Height, area, roof, attachment, boundaries, overlays and pool safety are assessed together. Check with a private building certifier; lowering a deck below one metre does not automatically remove approval requirements.
How much do deck stairs and balustrades cost?
Stairs and balustrades are quoted separately according to the design, rise, width, materials, fixings and access. Ask for these items to be clearly identified in your quote.
How long does it take to build a deck?
A straightforward ground-level deck usually takes three to seven days on site. Elevated and multi-level decks generally take two to four weeks including footings and cure time.
What timber is best for Gold Coast decking?
Spotted gum and blackbutt perform well in our climate for durability and colour retention. Merbau is a lower-cost option but leaches tannin early on.
Is a decking quote fixed price?
A written quote fixes the agreed scope, subject to its inclusions, exclusions and allowances. Changes or unforeseen conditions are discussed and documented under the quote and contract variation process before additional work.
