Composite Decking Cost in Melbourne — 2025 Price Guide

Pricing transparency matters — here is a realistic breakdown of what you can expect to pay for composite decking in Melbourne.

Prices above include GST. Installation cost varies with deck height, site access, subframe material (treated pine vs aluminium) and design complexity. Call us or use the form below for a project-specific quote.

Why supply direct from Outdeco Living? As a wholesale supplier open to the public, trades and builders, our board prices are significantly lower than retail. Most customers save $15–$40 per m² compared to buying through a hardware chain or retail decking store.

Why Melbourne Homeowners Choose Composite Decking

Zero maintenance — seriously

No sanding. No oiling. No sealing. No annual staining. A composite deck needs nothing more than a sweep and an occasional hose-down with water. Over 10 years, this saves the average Melbourne homeowner $4,500–$9,000 in timber maintenance costs — plus dozens of weekends.

Built for Melbourne’s unpredictable climate

Melbourne’s temperature can swing from 8°C in the morning to 38°C by afternoon. Our composite boards are engineered for this — they expand and contract within design tolerances, maintaining structural integrity through thousands of heat-cool cycles. They won’t crack, cup or split the way untreated timber does under the same conditions.

Termite-proof and moisture-resistant

Composite boards contain no digestible organic material on their outer shell, making them completely unappealing to termites. The fully capped polymer surface also prevents moisture absorption — no swelling, no rot, no mould taking hold inside the board. This is a significant advantage in Melbourne’s wetter seasons and in gardens with irrigation systems.

UV-stabilised colour that lasts

Our composite boards include UV inhibitors in the capping layer to slow colour fade. A quality capped board will retain its colour for 15+ years with normal outdoor exposure. Cheaper uncapped boards fade noticeably within 3–5 years — our boards are not that product.

Slip-resistant surface

The embossed wood-grain surface on our composite boards provides grip in wet conditions, meeting the requirements of AS 4586 for residential outdoor use. This makes composite a safer choice than smooth-finished timber for pool surrounds, wet zones and homes with young children or elderly residents.

Eco-friendly and sustainable

Our composite decking is manufactured using recycled wood fibres and recycled plastic, diverting waste from landfill. Choosing composite over new-growth hardwood reduces demand for virgin timber. For Melbourne homeowners seeking a more sustainable outdoor build, composite is the responsible alternative to slow-growth hardwoods.

Composite Decking vs Timber — Which Is Right for You?

This is the question we get asked most. Here is an honest, side-by-side comparison based on real Melbourne conditions.

Our verdict: For Melbourne homeowners who want a beautiful, safe outdoor space and have zero interest in weekend maintenance, composite is the clear winner on total value. If you love the authentic grain and smell of real timber and are committed to annual oiling, Merbau is a great choice — and we supply that too. We’ll give you honest advice for your specific situation.

Supply Only or Fully Installed — Your Choice

Supply only: We supply composite decking boards, fixings and accessories direct from our Melbourne warehouses. Order online, collect from Campbellfield or Dandenong South, or arrange delivery across Melbourne and regional Victoria. Boards are sold per lineal metre or full pack — no minimum order for retail customers.

Composite Decking FAQ — Melbourne

Answers to the questions we get asked most often. These also appear in our structured FAQ schema for Google and AI search engines.

How much does composite decking cost per square metre in Melbourne?

Composite decking in Melbourne costs between $90 and $170 per square metre for supply only, depending on the board type and finish. A fully installed deck — including subframe, fixings, labour and delivery — typically ranges from $320 to $550 per square metre all-inclusive. For a standard 30m² ground-level deck in Melbourne, most homeowners budget between $10,000 and $18,000. Outdeco Living supplies boards at wholesale direct pricing, meaning you pay less per board than at retail. Contact us for a project-specific quote.

What is the difference between capped and uncapped composite decking?

Capped composite decking has a protective polymer shell bonded around the outside of the board. This shell resists staining, moisture absorption, UV fading and surface scratching far better than uncapped boards. Uncapped composite boards expose the wood-fibre core directly, which can absorb moisture over time, making them more susceptible to mould, colour fade and minor swelling. For Melbourne’s climate — with intense UV summers and wet winters — fully capped boards are the recommended choice. All composite boards stocked by Outdeco Living are fully capped.

Is composite decking better than timber for Melbourne?

For most Melbourne homeowners, composite decking delivers better value over time. Composite requires no annual oiling or sanding, saving $4,500–$9,000 in maintenance over 10 years on a 30m² deck. It is termite-proof, won’t warp or splinter, and handles Melbourne’s dramatic temperature swings without cracking. Timber has a lower upfront board cost and delivers an authentic natural grain that some homeowners prefer. If you want beauty without any ongoing maintenance commitment, composite is the smarter long-term investment. If you love real timber and will commit to annual oiling, Merbau remains a great choice — and we supply both.

How long does composite decking last in Australia?

Quality composite decking lasts 20–25 years in Australian outdoor conditions. Premium capped boards carry structural warranties of 15–25 years, depending on the brand and profile. Unlike timber, which deteriorates significantly without regular maintenance, composite boards are engineered to resist UV degradation, moisture, termites and temperature cycling throughout their lifespan. Longevity depends on choosing a fully capped board, correct installation with adequate subframe support, and basic annual cleaning to prevent surface organic build-up.

Does composite decking get too hot to walk on in summer?

All decking surfaces absorb heat in direct sun. Composite boards with heat-reflective pigments and lighter colour options run cooler than dark-coloured alternatives. In full Melbourne summer sun, a light-coloured composite board (e.g. grey ash, natural cedar) sits approximately 10–15°C cooler than a dark charcoal board. For barefoot comfort in summer, we recommend lighter colour choices and shade structures over high-use areas. This applies equally to timber — dark stained merbau in full sun gets very hot underfoot as well.

Is composite decking slippery when wet?

No. Quality composite boards have an embossed wood-grain surface texture that provides grip in wet conditions. Many profiles are tested and rated to AS 4586 wet slip resistance standards at Class R11 or higher, which is suitable for residential outdoor use including pool surrounds. For areas that see constant water exposure, ask us to recommend a profile with a higher wet slip rating. Composite is generally safer underfoot when wet than smooth-finished or worn timber boards.

Can composite decking be laid over an existing timber deck?

Sometimes yes — it depends on the condition of your existing subframe. If the joists and bearers are structurally sound, treated and level, composite boards can be re-boarded on top using hidden clip fixings. If the subframe is rotted, warped or termite-damaged, it must be replaced first. Installing composite boards over a compromised subframe voids the product warranty and creates an unsafe structure. We strongly recommend a professional inspection of your existing framing before deciding between a re-board and a full rebuild.

How do I clean composite decking?

Composite decking requires very little effort to keep clean. Sweep debris regularly to prevent organic build-up in the board grooves. Every few months, hose down with plain water. For stubborn dirt, algae or mould spots, scrub with a soft-bristle brush and mild soapy water, then rinse well. A low-pressure hose (under 1,200 PSI) is fine — avoid high-pressure washers, which can erode the board surface and void warranties. Never apply timber oil, deck stain or bleach to composite boards — they don’t require it and these products can cause permanent discolouration.

Does composite decking add value to my Melbourne home?

Yes. A well-built composite deck adds measurable value to a Melbourne property. Buyers appreciate a clean, low-maintenance outdoor entertaining space — and composite, unlike aged timber, does not signal “weekend maintenance project ahead.” Real estate agents consistently rank quality outdoor living areas among the top features Melbourne buyers pay a premium for. A composite deck in good condition typically returns $1.20–$1.50 in property value for every $1.00 invested, making it one of the stronger renovation returns for Melbourne homes.

Is composite decking resistant to termites and moisture?

Yes to both. Termites cannot digest the plastic polymer in the board capping — composite provides no food source, making it completely unappealing to termites. The capped polymer shell also prevents water absorption, eliminating the rot and swelling issues common in untreated or under-maintained timber. For poolside and irrigation-exposed areas, composite is the preferred material for this reason. Important note: while the composite boards are termite and moisture-proof, your subframe (joists and bearers) should still be H4-treated pine or steel to maintain full under-deck protection.

What colours are available in composite decking?

Composite decking is available in a wide range of wood-grain finishes, from warm teak, golden oak and walnut tones through to contemporary charcoal, slate grey and silver grey. Outdeco Living stocks boards in multiple colour options — current availability varies by board profile and changes with stock. We strongly recommend ordering samples before committing to a colour, as outdoor lighting, surrounding materials and landscaping all affect how a colour reads on your deck. Sample packs are available from both our Campbellfield and Dandenong South locations.

Do I need council approval to build a composite deck in Melbourne?

It depends on the size and height of your deck. In Victoria, decks under 800mm above natural ground level and under 100m² generally do not require a building permit for Class 1 dwellings, provided they meet local council setback rules. Decks in Bushfire Attack Level (BAL) zones have additional requirements around materials and construction methods — composite decking’s fire performance should be confirmed against your BAL rating. Rules vary by council, so check with your local authority or a registered building practitioner before starting construction. Outdeco Living can recommend Melbourne-based installers experienced with local permit requirements.
