Pool deck cost on the Sunshine Coast
A typical Sunshine Coast pool deck — 45m² of hardwood wrapping a standard 8m × 4m rectangular pool — lands between $15,000 and $25,000 installed. Composite pool decks of the same size run $17,000–$28,000. The variation comes from coping choice, slip rating, substructure quality, and whether the pool is in or out of code compliance to start.
Quick answer — pool deck cost on the Sunshine Coast
| Pool deck size | Hardwood installed | Composite installed | Notes |
|---|---|---|---|
| Small pool surround (25–35m²) | $10,500–$17,000 | $12,500–$19,500 | 2.5–3m wide surround |
| Standard pool deck (40–55m²) | $15,000–$25,000 | $17,000–$28,000 | Full perimeter + entry zone |
| Large pool + entertaining (60–80m²) | $22,000–$36,000 | $25,000–$40,000 | Includes seating zones |
| Pool + spa combined surround | $28,000–$48,000 | $32,000–$54,000 | Higher coping complexity |
| Coping replacement only (linear m) | $280–$450/lin m | $320–$520/lin m | No deck rebuild |
Three things that drive Sunshine Coast pool deck cost
1. Slip rating and the 1.5m pool-zone buffer
BCA Part 3.10.1 requires slip-rated surfaces within 1.5m of pool water. On hardwood, that means grooved or ribbed profiles ($30–$50/sqm premium) for the inner 1.5m perimeter. Most decks split-spec this: slip-rated boards in the wet zone, smooth boards in the outer entertainment area. Done right it adds $250–$700 to a typical pool deck; done wrong (smooth boards everywhere) triggers a fail at council pool inspection.
2. Coping options — flush, raised, or bullnose
How the deck meets the pool edge changes both the look and the cost. Flush coping (deck level with pool edge, tile gap below) is cheapest at $250–$350 per linear metre. Raised timber coping (deck steps up at pool edge) runs $350–$500/lin m and looks high-end. Bullnose timber coping (rounded soft edge over the pool tile) runs $400–$600/lin m and is the safest underfoot. On an 8m×4m pool that’s 24 linear metres of coping — the difference between flush and bullnose is $3,500–$6,000.
3. Substructure beneath the pool deck
Pool decks sit on either ground-level posts (cheaper, $20–$40/sqm in substructure cost) or on a raised platform of treated pine bearers with proper drainage clearance (premium, $50–$80/sqm). For Sunshine Coast pools, raised-substructure is strongly preferred — it allows airflow under the boards, drainage from pool splash, and prevents rot in the subtropical humidity. Many cheaper quotes save here and the boards fail at the substructure within 8–12 years.

Frequently asked questions
Does a Sunshine Coast pool deck need council approval?
If the deck is attached to the pool fence or modifies the pool barrier, yes — Building Approval and pool barrier compliance certificate required. If the deck sits outside the pool barrier (separate fence between deck and pool), no approval needed for the deck itself but the barrier still needs to be certified.
Why are hardwood pool decks more popular than tile on the Sunshine Coast?
Heat. Tile in direct summer sun can hit 70–80°C — too hot to walk barefoot. Hardwood runs 12–20°C cooler. Slip rating is comparable when hardwood is grooved/ribbed. The aesthetic also leans tropical-coastal, which suits Sunshine Coast properties.
How long does a pool deck last on the Sunshine Coast?
Hardwood: 20–25 years for spotted gum/blackbutt with annual oil and bi-annual sealing. Merbau: 15–20 years. Composite: matches its warranty period (20–25 years for premium brands). All assume proper substructure with drainage.
Can I lay a new pool deck over existing concrete pool surround?
Usually yes — timber subfloor frame laid over concrete with appropriate drainage gap, then board on top. Adds $1,500–$3,000 vs starting from bare ground but avoids the cost of breaking up existing concrete. The deck sits 60–80mm above pool tile level, which can look intentional or awkward depending on detail.
What’s the cheapest pool deck option that’s still safe and legal?
Treated pine deck boards (not hardwood, not composite) with slip-rated inner zone, flush coping, and ground-level substructure — around $12,000–$16,000 for a 45m² build. Lasts 10–12 years on the Sunshine Coast (vs 20–25 for hardwood). The shortened lifespan is the real cost — over 25 years it works out more expensive than hardwood.
