Pool decking cost on the Byron Bay coast

By the WTD team · Updated May 2026

Pool decking sits in its own pricing band — above standard decking, below paving — because everything about the spec changes when water sits beside it. Slip resistance, drainage, chemical exposure, fixings, and council pool-fence interaction all push the rate. In Byron Bay 2026 expect $400–$800/sqm depending on material and complexity.

Quick answer — pool decking cost in Byron Bay

Why pool decking costs more than standard decking

A standard backyard deck has one main job: hold weight and look good. A pool deck has six. It has to be slip-resistant when wet, drain quickly so puddles don't form, tolerate chlorinated or salt-water splashes, sit at the correct height relative to coping and pool fencing, integrate with the pool's structural surround, and look coherent with the pool itself.

That pushes the per-sqm rate 30–60% above a flat backyard deck in the same material. Treated pine simply isn't a pool deck material in 2026 — the cost of properly treating and replacing it as it absorbs chlorine and salt-water splash makes it false economy. Every reputable Byron Bay decking builder will steer you away from pine for pool surrounds.

Slip resistance — grooved vs smooth boards

The single biggest spec decision after material is profile: smooth boards or grooved? Grooved (reeded) boards have parallel grooves milled into the wear face that channel water and improve grip when wet. Smooth boards read more elegant and clean more easily but are notably slipperier with surface water.

For pool surrounds in Byron specifically, grooved is standard. The council slip-resistance rating most pool-fencing certifiers look for is R10 or better; smooth-board installations rarely hit that out of the box without a separate non-slip coating that needs re-application every 2–3 years. Grooved hardwood hits R11 inherently.

Composite has its own slip story. Most modern composites (Modwood Natural Grain, Trex Transcend, NewTechWood UltraShield) have a textured surface that hits R10 inherently and stays slip-resistant through the product's lifetime — no re-coating, no degradation.

Drainage and the coping gap

Water pooling on a deck is the fastest way to destroy boards regardless of material. For pool surrounds the volume is much higher than a normal deck, so drainage design becomes critical. Three standard approaches:

Fall to drain

Most common. The deck is built with 1–2% fall away from the pool toward perimeter strip drains that connect to stormwater. Adds $40–$80/sqm to the build cost for trenches and grates.

Coping gap (5–10mm)

Deliberate gap between deck boards and pool coping that lets splash-water drain back into the pool. Cheaper but requires the pool to have an overflow / skimmer system that can handle the extra inflow.

Permeable composite system

For composite decks, some systems use elevated joist hardware that lets water drain through gaps between boards directly to the substrate below. Cleanest aesthetic but only works on a properly graded concrete substrate.

Council pool fencing rules in Byron Shire

The deck design has to comply with Byron Shire Council's pool fencing rules (Australian Standard AS 1926.1) — a 1.2m non-climbable barrier separating the pool from any deck area accessible to children under 5. The deck itself doesn't need fencing if it sits inside the pool fence; if it sits outside, the fence must run along the deck's pool-facing edge.

Two practical implications: any deck within 900mm horizontally of the pool fence cannot have anything within 900mm vertically that a child could climb (no chairs, planters, or BBQs against the fence), and the deck surface level relative to the fence base must maintain the full 1.2m fence height. If the deck is being built up over old paving, the fence may need raising at the same time — budget $1,500–$3,500 for fence modifications if so. Ballina and Tweed Shires have functionally identical rules.

Frequently asked questions

Can I build a pool deck over existing concrete around the pool?

Yes — a common Byron job. The existing concrete becomes the substrate for an elevated timber-or-composite subframe. Adds 80–120mm to the deck height which needs checking against pool fence compliance, but otherwise straightforward. Saves $2,000–$5,000 over removing the concrete first.

Do I need a permit for a pool deck in Byron Shire?

If the deck is more than 1m above natural ground level, larger than 25sqm, or attached to a dwelling — yes. Most pool decks meet at least one criterion, so plan for a building permit. Your decking specialist usually includes lodgement ($350–$800). The pool fence must also be inspected after the deck work.

How long does a hardwood pool deck last in Byron Bay?

With annual oiling and weekly freshwater hosedown during swim season: 25–35 years for merbau, 30–45 for spotted gum. Without consistent maintenance the lifespan halves — chlorine and salt exposure accelerates board degradation significantly versus a backyard deck.

Is composite better than hardwood for pool decks specifically?

For pure maintenance and slip safety, yes. For look against a high-end home, hardwood usually wins. The split in Byron quotes is roughly 60% hardwood, 40% composite for new pool surrounds in 2026, with composite gaining share each year as products mature.

How wide should the coping gap be between deck and pool?

5–10mm is standard — wide enough for water to drain through, narrow enough to be safe. Some installs use a flush profile with the gap covered by an L-shaped trim; others leave it open. Either is compliant. Coping itself is usually a separate scope from the deck, priced by the pool tiler.

Will the deck affect pool water temperature?

Marginal effect on water; noticeable effect on the surrounding microclimate. Timber decks reflect less heat than concrete or paving so the area around the pool feels cooler underfoot. Composite sits between the two — hotter than hardwood, cooler than concrete.
