Why Pool Deck Costs Vary So Much
When you start dreaming of a new pool deck, one of the first questions is always, “How much will it cost?” The answer depends on a few key factors: materials, size, design, and approvals.
On the Sunshine Coast, expect your pool decking project to fall roughly between $400 and $1,200 per square metre in 2025. The lower end suits simple ground-level decks with treated pine framing, while premium hardwoods or composite boards with complex layouts sit at the higher end.
Main Factors That Influence Pool Deck Pricing
1. Materials: Timber vs Composite
Timber has got to be a favourite if you’re looking for natural warmth and beauty. So many Aussies simply cannot resist local hardwoods like Spotted Gum or Blackbutt. They do cost more upfront, but age gracefully when well-maintained.
Composite decking, on the other hand, has surged in popularity for pool surrounds. It’s splinter-free, slip-resistant, and doesn’t require regular oiling. You’ll pay slightly more per board, but it saves years of maintenance, and hours and hours of downtime. These add up over the years. You have some thinking to do.
Basically, for many, the choice comes down to natural look versus convenience. You have to balance the time and cost of ongoing maintenance. It really is a “values call.” Here’s a quick guide comparing materials, average cost, and maintenance effort.
| Material | Average Cost (per m² installed) | Maintenance | Expected Lifespan |
| Treated Pine | $400–$550 | High | 10–15 years |
| Merbau / Spotted Gum | $600–$850 | Medium | 15–25 years |
| Composite (ModWood, Trex, Millboard) | $750–$1,200 | Low | 25+ years |
2. Size and Design Complexity
Larger decks naturally cost more, but the design plays a huge part in the cost and material choice.
- Straight layouts with minimal cuts are the most cost-efficient.
- Curved or elevated decks add complexity and structural work.
- Integrated stairs, seating, or privacy screens also lift the price but can add long-term value. Think lifestyle. Think how you want to enhance your outdoor living.
3. Site Access and Preparation
If your yard has tight access or uneven ground, expect extra time for site preparation and for framing. Pool decks often require additional substructure or waterproofing around coping edges. This last one is a detail that’s easy to overlook in generic quotes. That’s why you need dinky di deck builders, professionals who know what they’re doing.
4. Council Approvals and Certification
Any elevated or structural pool deck usually needs approval. This adds cost for engineering and certification but ensures your deck is safe, compliant, and covered by insurance. (If you’re unsure, check our Deck Approvals Guide: it’s a quick read and saves headaches later.)

How to Budget for a Pool Deck on the Sunshine Coast
A realistic budget for most Sunshine Coast homes looks like this:
- Compact timber pool deck (10–15 m²): around $6,000–$10,000
- Mid-size composite surround (20–30 m²): around $15,000–$25,000
- Large entertainer deck with stairs, fencing, and screens: $30,000+
Pro tip: Always get a site-specific quote. Every pool, slope, and material combination is different… even within the same suburb.
How to Get the Best Value from Your Investment
A well-built pool deck isn’t just about looks. It adds usable outdoor space, boosts property value, and can even make maintenance easier by improving drainage and reducing dirt transfer into your pool.
You’ll get the best results when you:
- Choose durable, slip-rated materials suitable for coastal weather.
- Ensure drainage and ventilation are planned from the start.
- Use a licensed, local builder familiar with Queensland conditions (such as Sunshine Coast Decking).
FAQs About Pool Deck Costs
How much does a pool deck cost on the Sunshine Coast?
The average cost for a pool deck on the Sunshine Coast ranges from $400–$1,200 per square metre in 2025. Smaller decks using treated pine or standard timber are more affordable, while premium hardwood or composite decks cost more but require far less maintenance over time.
Is composite decking more expensive than timber?
Yes, it can be. Composite decking (which itself comes in low budget to high luxury ranges) generally costs more to install than natural timber. But where they can really win out is with the long-term maintenance savings. Over time, installing a composite deck can be a better investment. Unlike timber, it won’t need sanding, sealing or oiling, and it stays splinter-free and slip-resistant for decades.
