Decking Brisbane

A well-built deck transforms your Brisbane outdoor living space. We connect you with QBCC-licensed deck builders who work with premium hardwoods and modern composite materials.

Outdoor Living, Brisbane Style

Brisbane's subtropical climate means you can use your deck year-round. Whether it's a ground-level entertaining area off the kitchen, a raised deck taking advantage of a sloping block, or a pool surround, decking adds functional living space and genuine property value.

The key decisions are material choice — timber or composite — and finding a builder who understands Brisbane's specific requirements for termite protection, drainage, and weather exposure.

Timber vs Composite Decking

Hardwood Timber

Merbau and Spotted Gum are Brisbane's favourite decking timbers. They offer unmatched natural beauty and warmth underfoot. Hardwood decking can be sanded back and re-oiled to look brand new, extending its life significantly.

  • ✓Natural beauty and warmth underfoot
  • ✓Can be sanded and refinished multiple times
  • ✓Cooler than composite in direct sun
  • ✗Needs annual oiling to maintain appearance
  • ✗Requires termite management strategy

Cost: $350 – $500/m² installed

Composite Decking

Composite decking combines wood fibres with plastic polymers for a low-maintenance alternative. Leading brands like Trex, Ekodeck, and ModWood offer realistic timber looks without the ongoing upkeep.

  • ✓Virtually zero maintenance — no oiling or staining
  • ✓Termite and rot resistant boards
  • ✓Consistent colour, will not splinter
  • ✗Can get hot underfoot in Brisbane summer
  • ✗Cannot be sanded or refinished

Cost: $400 – $600/m² installed

Brisbane Deck Building Requirements

Brisbane's building codes require specific termite management for all timber structures. Deck subframes must use termite-resistant timber or be protected with physical barriers like ant caps on stumps and posts. The high UV exposure means timber finishes need regular maintenance to prevent greying and splitting.

For any decking project valued over $3,300, Queensland law requires a QBCC-licensed builder. We connect you with licensed professionals who understand Brisbane's specific requirements for wind rating, termite protection, and council compliance.

Decking FAQs

Decking in Brisbane typically costs $250 to $600 per square metre installed. Treated pine decking starts from $250/m², hardwood timber (Merbau, Spotted Gum) ranges $350-$500/m², and composite decking costs $400-$600/m². Size, height off ground, design complexity, and site access all affect the final price.
Both work well in Brisbane, but the choice depends on your priorities. Hardwood timber offers a natural look and can be sanded and refinished, but needs annual oiling. Composite decking requires virtually no maintenance and resists termites, but costs more upfront and can get hotter underfoot in Brisbane's summer sun.
Spotted Gum and Merbau are the most popular decking timbers in Brisbane. Spotted Gum is an Australian hardwood with excellent durability (Class 1) and natural termite resistance. Merbau is a dense tropical hardwood with rich colour but is an imported species. Both handle Brisbane's humidity and UV well.
In Brisbane, decks under 10 square metres and less than 1 metre above ground are generally exempt from a building approval. Larger or higher decks require a building application through a private certifier. Decks near boundaries or on flood-prone land have additional requirements.
Yes. Brisbane is in Australia's highest termite risk zone. Timber deck substructures should use termite-resistant species or H3-treated framing. Physical termite barriers (ant caps) on posts and stumps are essential. Composite decking boards resist termites, but the timber subframe still needs protection.
