Composite Decking Price in Australia

Composite decking is very popular. Many homeowners now choose it over solid timber. This material mixes wood fibres with recycled plastics or uPVC. It offers good stiffness, durability, and low upkeep.

How Much Does Composite Decking Cost?
Installation typically costs between $250 and $400 per square metre. Prices vary. Deck size, job difficulty, and extra services affect the total cost. Initial costs are higher than some woods. But long-term benefits often justify this.

Labour Costs by Region (Australia)
Most builders charge $170 to $210 per m². Prices depend on deck size.

• Western Australia: $180 – $190 per m²
• Queensland: $185 – $190 per m²
• Victoria: $190 – $200 per m²
• New South Wales (NSW): $200 – $210 per m²

Builders usually inspect the site first. They then give a detailed quote.

Material Costs for Composite Boards
Brand prices differ. Understand product specs before choosing. Material costs alone are roughly $156 per m². Here are estimates for different deck sizes:

• 15m² deck: ~$2,340
• 24m² deck: ~$3,745
• 32m² deck: ~$4,995
• 40m² deck: ~$6,240
• 48m² deck: ~$7,490

Key Benefits Over Wood
Composite decks have clear advantages:

• Durability: Lasts long. Warranties often cover 25 years.
• Weather Resistance: Resists fading from sun. Handles water and fire well. Good for rainy areas or near fire pits.
• Stain Resistance: Resists stains from liquids and oils. Also fights mould and decay.
• Lightweight: Easier to handle than heavy wood. Boards come in manageable lengths (6′ to 24′).
• Low Maintenance: No yearly staining or sealing needed. Simple cleaning keeps it looking new.

What Increases the Price?
Several factors raise costs:

1. Materials: Quality and brand affect prices. Composite boards themselves cost more. Extra features like steps, rails, or lights add expense. Meeting building codes may also increase cost.
2. Size: Larger decks use more materials and labour. Example: A 15m² deck costs about $2,340 for materials plus $2,550 for labour ($170/m²).
3. Design Complexity: Simple designs cost less. Curved decks or unique patterns need more cutting and skill. This increases labour time and price.
4. Builder & Installation: Labour rates change with job complexity. Basic decks might cost $80/m² for labour. Complex ones could reach $180/m². Permits or foundation work (like concrete) add costs too. Always get clear quotes.

Types of Composite Decking
Two main types exist:

1. PVC-Based: Looks like real wood with a matte finish. Often cheaper initially. But it needs frequent resealing (possibly yearly). It may be less eco-friendly.
2. HDPE-Based: Very durable. Resists insects and rot. Can last decades. Uses less plasticizer and is more recyclable. Looks like wood without needing oils or resins. Generally safer for health and the environment.

Maintaining Your Composite Deck
Maintenance is simple. Clean occasionally with soapy water. Avoid bleach. Rinse well and let the deck dry completely. Do not seal or paint it until it’s fully dry. Always use safety gear like glasses and gloves when working on it. Composite decks handle weather, resist chemicals, and stay easy to clean.
