Merbau (also known as Kwila) is Melbourne’s most popular hardwood decking timber. Its rich reddish-brown colour, natural durability, and resistance to rot and insects make it ideal for Melbourne’s temperate climate with wet winters and warm summers.
Cost
Merbau decking costs $350–$550 per square metre installed in Melbourne, including bearers, joists, and finishing. A standard 20m² deck typically costs $7,000–$11,000.
Maintenance
Annual oiling is essential to maintain colour and prevent greying. Use a quality decking oil (Cutek, Intergrain) applied every 12 months. Without maintenance, merbau turns silver-grey — attractive to some, undesirable to others.
