555 Deck Builders in Australia
A deck builder designs and builds timber or composite outdoor decks, stairs, balustrades and related framing work for homes. They help plan the layout, prepare the site, set posts and joists, install decking boards, and finish the structure for safe everyday use. A good deck builder will also consider drainage, access, fall protection and local approval needs before work starts. For raised or complex decks, it is important to check whether council or certifier approval is needed and confirm the builder follows the rules that apply in your state. Every deck builder listed here is an ABN-registered business from the Australian Business Register.

Deck Builder Licensing in Australia
Licensing varies by state; raised decks may need council or certifier approval. Check the state regulator register before hiring and confirm the builder holds any required licence or registration for the work in your area. Regulators you can check include NSW Fair Trading, Building and Plumbing Commission VIC, QBCC, Building and Energy WA, Consumer and Business Services SA, CBOS Tasmania, Access Canberra and the NT Building Practitioners Board.
What Affects the Cost
Deck building cost depends on the deck size, height, site access, ground conditions, materials, stairs, balustrades, waterproofing, demolition of old structures and any approval or engineering needs. Repairs may be simpler than a full replacement, while custom features and difficult sites usually add more work. Ask for three written, itemised quotes so you can compare what is included and avoid surprises.
How to Find a Good Deck Builder
Look for a deck builder with clear experience in the type of deck you want, whether timber, composite, low-level or raised work. Ask for written quotes, photos of recent jobs, proof of insurance and any required state licence or registration, and check the relevant regulator register. A good builder will explain the build method, the materials they recommend, and any approval steps before work begins.
