Treated Pine Decking ($180 – $280/m²)
Treated pine is the most budget-friendly decking option. It's pressure-treated to resist rot, termites, and fungal decay, making it suitable for Melbourne's climate. While it's economical upfront, treated pine requires regular staining or sealing (every 2–3 years) to maintain appearance and maximise lifespan. Expect 10–15 years of service with proper care.
Best for: Rental properties, holiday homes, budget-conscious homeowners.
Merbau Decking ($300 – $550/m²)
Merbau is the most popular hardwood decking choice in Melbourne — and for good reason. This durable Indonesian timber offers a rich, warm reddish-brown colour that ages beautifully to a silver-grey if left untreated. Merbau is naturally resistant to termites and rot, with a lifespan of 20–30 years when properly maintained. It requires occasional oiling to preserve its colour, but many homeowners love the natural silver-grey patina.
Best for: Family homes, entertaining areas, high-traffic decks.
Composite Decking ($350 – $650/m²)
Composite decking (brands like ModWood, Trex, and Sevenoak) is made from a blend of wood fibres and recycled plastics. It mimics the look of timber without the ongoing maintenance — no sanding, staining, or sealing required. Just an occasional wash with soap and water. Quality composite decking can last 25–30 years without fading, warping, or splintering.
The higher upfront cost is offset by virtually zero ongoing maintenance. For busy Melbourne families, composite is an increasingly popular choice.
Best for: Low-maintenance lifestyles, pool surrounds, coastal areas.
Factors That Affect Decking Cost in Melbourne
The decking cost Melbourne homeowners pay isn't just about materials. Consider these additional factors:
- Site access: Difficult access (narrow side gates, rear-only access, steep slopes) adds labour time and cost.
- Deck height and complexity: Ground-level decks are cheapest. Elevated decks require more substructure, railings, and sometimes building permits.
- Demolition and removal: Removing an existing deck adds $500–$2,000 depending on size and material.
- Council permits: Decks over 1 metre high usually require a building permit in Melbourne. Allow $500–$1,500 for engineering and permit fees.
- Railings and balustrades: Glass, stainless steel, or timber balustrades add $150–$400 per linear metre.
- Finishes and treatments: Oil, stain, or paint adds $15–$30/m² for materials plus labour.

Frequently Asked Questions
What is the cheapest decking material in Melbourne?
Treated pine is the most affordable option at $180–$280/m² installed. While it requires regular maintenance (staining/sealing every 2–3 years), it provides a solid, functional deck at the lowest upfront cost.
How long does Merbau decking last in Melbourne's climate?
Merbau decking typically lasts 20–30 years in Melbourne when properly installed and maintained. Its natural oils make it resistant to termites and rot, and it handles Melbourne's temperature swings exceptionally well.
Is composite decking worth the extra cost?
For many homeowners, yes. While composite costs more upfront ($350–$650/m²), it requires virtually no maintenance — no sanding, staining, or sealing. Over 25–30 years, the savings on maintenance products and labour can offset the initial investment.
Do I need a permit for a deck in Melbourne?
In most Victorian municipalities, a building permit is required for decks over 1 metre above ground level. Ground-level decks under 1 metre may not need a permit but should still comply with building regulations. We handle all permit requirements as part of our service.
Does the decking cost include removal of the old deck?
Not always — demolition and removal are usually quoted separately. Allow $500–$2,000 for removing an existing deck, depending on size, materials, and disposal requirements. We always provide a detailed breakdown so there are no surprises.
