Greenhill Composite decking has rapidly become one of the most popular alternatives to traditional timber decking in Australia. With its unmatched durability, low maintenance requirements, and modern aesthetics, it offers homeowners and commercial builders a long-lasting solution that stands up to the harsh Australian climate. Whether you’re renovating a backyard, building a new outdoor entertainment area, or looking for a fire-resistant, eco-friendly decking material, composite decking delivers performance, beauty, and peace of mind.
What is Composite Decking?
Composite decking is a man-made material composed of a mixture of recycled wood fibres, plastics, and binding agents. These elements are combined to form durable, weather-resistant boards that mimic the look and feel of natural timber—without the drawbacks.
Unlike timber, which can warp, rot, or attract termites, composite decking is engineered to remain strong and stylish with minimal upkeep. It is available in a wide range of colours, finishes, and profiles, making it suitable for both residential and commercial outdoor applications.
Benefits of Composite Decking in Australia
1. Unmatched Durability
Composite boards are designed to withstand extreme heat, heavy rainfall, salt air, and UV exposure, making them ideal for the diverse Australian climate. Unlike wood, they won’t crack, splinter, or fade over time.
2. Low Maintenance
Say goodbye to staining, sealing, or sanding. Composite decking requires just occasional cleaning with water and mild soap, significantly reducing long-term upkeep and costs.
3. Eco-Friendly
Most composite decking is made from 95% recycled materials, including reclaimed wood and plastic, diverting waste from landfills and reducing the need for virgin timber harvesting.
4. Slip and Fire Resistance
Many composite brands offer anti-slip surfaces and BAL (Bushfire Attack Level) rated products, essential for properties in bushfire-prone areas of Australia.
5. Consistent Aesthetic
Composite boards offer a uniform appearance with no warping, discolouration, or knots, ensuring a polished and modern look across the entire deck.

Installation Tips for Composite Decking in Australia
1. Ventilation Matters
Always install composite decking with proper subfloor ventilation to avoid moisture build-up.
2. Use Approved Fasteners
Use concealed fixing systems or fasteners recommended by the decking manufacturer to prevent board damage and ensure a clean finish.
3. Allow for Expansion
Composite materials expand and contract with temperature. Allow proper spacing between boards and follow manufacturer instructions.
4. Frame Compatibility
Composite boards should be installed on a galvanised steel or treated timber frame to prevent corrosion or degradation.
Design Ideas Using Composite Decking
1. Pool Surrounds
The slip-resistant and moisture-resistant nature of composite decking makes it ideal for pool areas and spas.
2. Rooftop Decks
Lightweight and stable, composite decks can be safely installed on rooftops, offering an elegant and safe outdoor retreat.
3. Multi-Level Outdoor Spaces
Combine different composite colours to define dining, lounging, and barbecue areas.
4. Commercial Decking
Composite is ideal for hospitality venues, boardwalks, and alfresco zones where heavy foot traffic and compliance with safety codes are key.
How to Clean and Maintain Composite Decking
Maintenance is simple:
- Routine cleaning with a broom and hose keeps debris and dirt at bay.
- For stubborn stains, use a soft-bristled brush and composite decking cleaner.
- Avoid abrasive tools or high-pressure washers which may damage the finish.
- Promptly clean any food or oil spills to avoid long-term staining.
Is Composite Decking Worth It?
Yes—while the upfront cost of composite decking is generally higher than traditional timber, the lifetime value is significantly better. The reduction in maintenance, repairs, and replacements—along with its stylish, long-lasting appearance—makes composite decking an investment in the future of your home or business.
