The most common decking decision Melbourne homeowners face is Merbau vs treated pine. Both are good options, but they suit different situations and budgets.
Merbau Hardwood
Merbau is the premium choice. It's a dense, oily hardwood that's naturally resistant to insects and rot. Fresh Merbau has a rich red-brown colour that weathers to a silver-grey if left unoiled, or maintains its warm tones with regular oiling.
Cost: $250–$425/m² installed
Lifespan: 25–40 years with proper maintenance
Maintenance: Oil every 1–2 years
Best for: Homeowners who want a premium look and are happy to maintain it
Treated Pine
Treated pine (H3 or H4 rated) is the budget-friendly option. It's structurally sound and, when properly maintained with decking oil or paint, can look great. It's lighter in colour and doesn't have the same natural warmth as hardwood.
Cost: $150–$250/m² installed
Lifespan: 15–25 years with maintenance
Maintenance: Paint or oil every 2–3 years
Best for: Larger deck projects where budget is a priority
My Recommendation
For most Melbourne homeowners I recommend Merbau. The upfront cost difference isn't massive, and the result looks significantly better. Treated pine is fine for large decks where budget matters, or for decks you plan to paint.
