1. What Are They Made Of? A Timber vs Composite Decking Overview
Timber Decking
Timber decking is made from natural wood. In Melbourne, popular hardwoods include Spotted Gum, Jarrah, Merbau, and Blackbutt. These species are chosen for their strength, rich colours, and natural resistance to weather. Softwood options, like treated pine, are more affordable but need extra care.
In the ongoing Timber vs Composite Decking discussion, it’s important to understand the materials that set them apart.
Pros: Timber provides a natural look and texture that many homeowners prefer. It feels cooler underfoot in summer and can be stained to change colour.
Cons: Without regular treatment, timber can splinter, fade, or become slippery. Maintenance is a must.
Composite Decking
Composite decking is a blend of wood fibres and recycled plastic. Modern versions are often “capped” with a protective layer, giving them excellent resistance to fading, moisture, and scratches.
In Melbourne, you’ll find brands like Trex, NewTechWood, and ModWood, each offering boards in various shades and finishes. High-end composites are designed to mimic the look of natural wood.
2. Cost & Long-Term Value
The Timber vs Composite Decking comparison transcends just costs; it involves understanding long-term value and maintenance.
Initial Investment
Timber decking is generally cheaper upfront. Supply and installation average between $220–260 per square metre. Composite decking costs more, averaging $350–500 per square metre installed.
Lifetime Costs
The real difference shows over time. Timber needs regular sanding, staining, and sealing, which adds to yearly costs. Composite decking, on the other hand, only requires cleaning with mild soap and water.
Over a 10–15 year period, the cost of maintaining timber can exceed the higher upfront cost of composite. Many homeowners find that composite decking pays for itself within 2–3 years through reduced maintenance.
3. Durability & Maintenance
When evaluating your options, consider the Timber vs Composite Decking in terms of durability and maintenance needs.
Timber
Timber decking is vulnerable to Melbourne’s mix of hot summers and wet winters. Common issues include:
- Fading under UV exposure.
- Warping and cracking with temperature changes.
- Mould and termites, especially in shaded or damp areas.
To extend its life, timber must be sealed and stained annually. Without maintenance, its appearance and strength decline quickly.
Composite
Composite decking is built to withstand harsh conditions. It is:
- Resistant to rot and pests.
- UV-stable, so it keeps colour longer.
- Splinter-free, making it safer for kids and pets.
It requires no sanding, staining, or sealing — just occasional cleaning. Many composite boards also come with warranties of up to 25 years.
4. Comfort & Liveability
Comfort is yet another factor to weigh in the Timber vs Composite Decking debate when choosing your ideal deck.
Heat Management
Timber stays cooler underfoot in Melbourne’s summer heat, which makes it pleasant to walk on barefoot. Composite can become hotter, especially darker colours, but lighter shades stay more comfortable.
Safety & Use
Timber can splinter over time and may become slippery when wet if not treated. Composite boards are splinter-free and often designed with slip-resistant finishes, making them a safer choice around pools or for families with children.
5. Aesthetic Appeal & Style
Timber’s Natural Warmth
Timber offers authentic charm. Its grain patterns and rich colours create a warm, organic look. Because it can be sanded, stained, or painted, homeowners have flexibility to refresh the style over time.
Composite Design Options
Composite decking offers modern consistency. Boards are available in a wide range of colours, from natural wood tones to contemporary greys. High-end composite closely mimics timber, but without fading or irregularities.
6. Environmental Impact
In the realm of aesthetics, Timber vs Composite Decking presents homeowners with very different visual options.
Timber Decking
Timber is a renewable resource when sourced responsibly. Look for FSC (Forest Stewardship Council) certification to ensure sustainable harvesting. At the end of its life, timber can be recycled or reused in other building projects.
Composite Decking
Composite boards are made using recycled plastic and reclaimed wood fibres, helping reduce landfill waste. However, recycling composite decking at the end of its life is more challenging compared to timber.
7. Melbourne Climate Considerations
Understanding the environmental impact of both choices is crucial in the Timber vs Composite Decking discussion.
Melbourne’s climate is unique. It combines strong UV rays, hot summers, cool winters, and frequent rain. These conditions test any outdoor material.
- Timber decking: Feels comfortable underfoot but needs constant care to protect against sun and moisture damage.
- Composite decking: Holds up well under UV exposure and heavy rain, with little need for maintenance.
For sun-exposed areas like backyards without shade, composite is often the better option. In shaded or protected areas, timber can still perform well if properly maintained.
8. Which Is Best for Your Melbourne Home?
Ultimately, the question remains: Timber vs Composite Decking, which is the better option for your unique needs?
Choose Timber if:
- You want the natural look and texture of real wood.
- You enjoy DIY care and don’t mind regular maintenance.
- You’re looking for a more affordable initial investment.
Choose Composite if:
- You prefer low-maintenance living.
- Your deck will be exposed to direct sun or heavy rain.
- You want long-term durability and consistent style
FAQs
How long does timber decking last in Melbourne?

Can composite decking fade or warp?
High-quality composite boards are built to resist fading and warping. Most include long warranties for peace of mind.
Which decking is better for around pools?
Composite is often the better choice. It resists water damage and is slip-resistant, making it safer for wet areas.
Is composite decking worth the cost?
Yes, for many homeowners. The reduced maintenance and longer life often balance out the higher upfront price.
Conclusion
In conclusion, the Timber vs Composite Decking choice is influenced by various factors including maintenance, cost, and personal preference.
Timber and composite decking both have strong advantages. Timber decking delivers classic beauty and a lower starting price but requires regular care.
