When planning an outdoor area in Australia, one of the most important decisions you’ll make is choosing between composite decking vs timber. Both have their merits—but only one truly stands out when it comes to weather resistance, long-term maintenance, and sustainability.
In this detailed decking comparison, we’ll help you weigh the pros and cons of each material, so you can confidently select the best option for your climate, budget, and lifestyle.
The Basics: What Are We Comparing?
| Feature | Timber Decking | Composite Decking |
|---|---|---|
| Material Composition | Natural hardwood or softwood | Recycled wood fibres + polymers |
| Appearance | Natural grain and colour | Wood-like texture, consistent finish |
| Sustainability | Dependent on sourcing (can involve logging) | Recycled and low environmental impact |
| Lifespan | 10–15 years (with maintenance) | 25+ years (low maintenance) |
| Price (initial) | Lower upfront cost | Higher upfront but lower over time |
Explore our full range of decking Australia options designed for harsh climates.
1. Durability & Weather Resistance
Australia’s climate is notoriously harsh. Whether you’re in the dry outback, the tropical north, or the salty coastal zones, your decking material needs to withstand it all.
Timber Decking:
-
Susceptible to rot, termites, cracking
-
Requires oiling to prevent weather damage
-
Can fade under UV exposure
Composite Decking:
-
Resists moisture, rot, UV damage, and pests
-
No cracking or splintering over time
-
Ideal for humid, coastal, and sunny regions
“We live near the Sunshine Coast, and our old timber deck kept warping. We switched to composite decking, and it’s been flawless—even during storms.” – Aaron L., QLD
2. Maintenance Requirements
Let’s face it—no one wants to spend weekends sanding and oiling timber.
| Task | Timber Decking | Composite Decking |
| Annual Sanding | Required | Not required |
| Regular Oiling | Essential for preservation | Not needed |
| Cleaning | Deep clean needed | Occasional rinse and mild soap |
“We saved hundreds each year on oiling products and labour after switching to composite decking vs timber.” – Melissa P., VIC
3. Visual Appeal
Aesthetics matter—especially for decks that are visible from the kitchen, pool, or backyard.
Timber:
-
Offers a natural, warm look
-
Grain varies from board to board
-
Prone to fading and discolouration
Composite:
-
Consistent colour and texture across all boards
-
Available in multiple wood tones and finishes
-
UV-protected for long-term colour retention

4. Cost Comparison: Initial vs Lifetime Value
| Factor | Timber Decking | Composite Decking |
| Initial Cost | $70–$100/m² | $90–$130/m² |
| Annual Maintenance | $300–$500 (materials & labour) | Negligible |
| Total 10-Year Cost | $7,000+ | $9,000 (lower after year 10) |
While timber decking may cost less upfront, composite proves more affordable in the long run due to lower maintenance and longer lifespan.
“Over 8 years, we’ve spent less than $100 maintaining our composite deck. With timber, it used to be $400 a year.” – Nathan R., NSW
5. Sustainability & Environmental Impact
Timber:
-
Often harvested from old-growth forests
-
Must be FSC certified to be eco-friendly
Composite:
-
Made from recycled plastics and reclaimed wood
-
Diverts waste from landfill
-
Contributes to circular building economy
“It felt great knowing our deck helped keep plastic out of the ocean.” – Sarah Y., WA
