Thinking about upgrading your outdoor area? Composite decking is one of the smartest and most stylish choices you can make. It’s durable, low-maintenance, and designed to look amazing year-round—no matter what Sydney’s weather throws at it.
Whether you’re dreaming of relaxed BBQs, evening drinks under the stars, or a safe and splinter-free play area for the kids, this guide will walk you through everything you need to know about composite decking. From the key benefits and materials to popular brands, design tips, and installation advice—let’s turn your dream deck into a reality.
Why Choose Composite Decking Over Timber?
Composite decking has quickly become the go-to choice for homeowners who want the look of timber without the hassles that come with it.
Here’ why Composite decking has become so popular:
- Built to Last: Unlike traditional wood, composite decking resists fading, splintering, and rotting. It stands up to moisture, pests, and sun—perfect for harsh Aussie conditions.
- Low Maintenance: Forget the annual sanding and oiling. A quick wash with soap and water is usually all it takes to keep your deck looking fresh.
- Eco-Friendly: Most composite boards are made from recycled plastics and reclaimed wood, making it a sustainable alternative to timber decking.
- Consistent Appearance: No knots, cracks, or warping—just clean, uniform boards that stay true to colour.
What Is Composite Decking Made From?

Composite decking is crafted from a mix of wood fibres and recycled plastic, bonded together with adhesives and treated for durability. The result is a product that looks like natural timber but performs far better in outdoor conditions.
- Wood fibres: Usually reclaimed sawdust or wood shavings that give the decking a natural texture and feel.
- Plastic: Often recycled polyethylene or polypropylene that adds strength and water resistance.
- Additives: UV inhibitors, colour stabilisers, and anti-mould agents help protect against fading and weather damage.
Top Composite Decking Brands to Know
When investing in composite decking, quality matters. Here are a few of the best-known names on the market:
- Trex: Industry leader with a huge range of styles and colours. Known for high durability and fade resistance.
- Millboard: Premium handcrafted decking with the authentic look of real timber. Renowned for its wood-free core, exceptional durability, and unmatched slip resistance.

Choosing the Right Composite Decking
Before you buy, consider these key factors:
- Durability: Look for boards with solid warranties and proven resistance to moisture, UV rays, and scratches.
- Style: Think about colour, grain texture, and finish. Do you want the look of natural timber or a sleek, modern surface?
- Price: Composite decking costs more upfront than timber, but you’ll save big on upkeep over time.
- Slip Rating: Especially important around pools or in shady areas—make sure your choice meets local safety standards.
What to look for when choosing a deck installation company fou your Composite deck
Choosing the right deck builder can make all the difference. Look for a team with solid experience, the right licences, and a portfolio that shows off their past work.
A good installer will be upfront about costs, walk you through the process, and keep the communication clear from start to finish. It’s also worth checking reviews and making sure they’ve worked with the materials you’ve chosen—especially if you’re going with composite decking. When you’re investing in a new deck, you want to know it’s in capable hands.
Keeping Your Composite Deck Looking New
Maintenance is simple—and that’s one of the biggest perks.
- Clean Regularly: Use a soft brush, mild soap, and water. Rinse well.
- Avoid Harsh Cleaners: No bleach or high-pressure washing.
- Inspect Annually: Check for loose screws, debris build-up, or signs of wear.
Some brands recommend a protective treatment, but most boards are good to go straight from the box.
Deck Design Ideas to Inspire You
Composite decking gives you loads of flexibility to create an outdoor space that suits your lifestyle.
- Multi-level decks: Define zones for dining, lounging, or entertaining.
- Apartment decks: Add informal dining and entertaining spaces
- Mix colours and patterns: Add borders or use contrasting tones for a custom look.
- Built-in seating & planters: Integrate features that boost both style and function.
- Lighting: LED strip lighting or step lights enhance safety and mood.
- Fire pits: A great way to make your deck an all year feature and extend its use
Cost Comparison: Composite vs Timber Decking
While composite decking costs more upfront, it often comes out ahead in the long run.
| Decking Type | Initial Cost | Maintenance Costs | Lifespan | Overall Value |
| Timber | Lower | High (staining, repairs) | 10–15 years | Medium |
| Composite | Higher | Low (just cleaning) | 25+ years | High |
So while timber might seem cheaper at first, composite decking typically delivers better value over time.
