Real-world examples
Treated pine, ground level$3,000 – $6,000
Merbau hardwood deck$7,000 – $12,000
Elevated composite deck$13,000 – $22,000
What affects the price
— Board material. Treated pine is cheapest; hardwood mid-range; composite highest up front but near zero maintenance.
— Deck height & footings. Elevated decks need more structure, posts and footings — and often balustrade.
— Site access & ground. Sloping, rocky or hard-to-reach sites add labour and excavation.
— Size & shape. Larger and non-rectangular decks use more material and cutting time.
— Extras. Stairs, balustrade, built-in seating and lighting all add to the total.
Tips before you post
— Composite costs more to install but saves on oiling and sanding over its life.
— Decks over a certain height or area may need council approval — ask your builder.
— Merbau is the most popular hardwood in Australia and a good value middle ground.
