Frequently Asked Questions About Merbau Decking Installation in Greenslopes
Is Merbau a good wood?
Yes, merbau is a popular hardwood decking choice in Australia: naturally durable, termite resistant and needs no chemical treatment. Boards retail from about $8–$15 per linear metre. It does leach red tannins in the first few rains, which wash onto surrounding paving, so hose the deck down after installation.
Is Merbau native to Australia?
No, merbau is imported from Southeast Asia and the Pacific, mainly Indonesia, Papua New Guinea and Malaysia. It's sold widely through Australian timber yards and hardware stores from about $8–$15 per linear metre. Local alternatives with similar durability include spotted gum and ironbark, both grown and milled in Australia.
Why is Merbau so expensive?
Merbau costs more than treated pine because it's a slow-growing imported hardwood with natural termite and rot resistance, needing no chemical treatment. Expect $8–$15 per linear metre for boards versus $4–$7 for treated pine decking. Supply has also tightened as sustainably certified merbau gets harder to source.
How much does a timber deck cost in Australia?
A basic treated pine deck (20m²) costs $4,000–$8,000 installed. Hardwood decking (Merbau, Spotted Gum) costs $6,000–$15,000 for the same size. Composite decking (Trex, Millboard) costs $8,000–$18,000 — more expensive upfront but lower lifetime maintenance cost. Elevated decks cost significantly more due to structural requirements.
Do I need council approval for a timber deck?
Decks over 1m above ground, attached to the house, or exceeding area thresholds (varies by state and council) require a building permit. In most states, a ground-level deck under 1m high with area under 10–18m² is exempt. Decks in bushfire-prone areas require BAL-rated materials. Always check with your council or building surveyor before starting.
What is the best timber for an outdoor deck in Australia?
Hardwoods: Merbau (durable, affordable, reddish-brown), Spotted Gum (beautiful grain, extremely durable), Blackbutt (light blonde, durable). All are rated Class 1–2 for above-ground durability. Treated pine is budget-friendly but requires regular oiling. Composite decking (timber and recycled plastic) has lowest maintenance but looks less natural.
How often does a timber deck need to be oiled or stained?
Merbau and most hardwood decks need oiling every 12–18 months to maintain appearance and UV protection. Treated pine needs sealing or staining every 12 months. Oil your deck when water no longer beads on the surface. Clean thoroughly before re-oiling. Composite decking requires only cleaning — no oiling needed.
What is composite decking and is it worth the premium?
Composite decking is made from a blend of recycled wood fibre and plastic — it won't rot, splinter, or need oiling. Brands like Trex, Modwood, and Millboard cost $180–$400/m² installed vs $120–$250/m² for hardwood. For families with children (no splinters), pool decks (moisture-resistant), and those who prefer low maintenance, composite is worth the premium.
