Build the Perfect Australian Deck
A timber deck isn’t just an outdoor feature — it’s an extension of your lifestyle. It’s where families gather, friends relax, and summer evenings stretch long into the night. But if you’re planning to build or renovate your deck, one question always comes up first:
Should you choose hardwood or composite decking?
Both offer beautiful results, but they perform very differently under Australian conditions.
At AJ Flooring, we’ve been crafting and maintaining decks across Sydney for more than 40 years. We’ve seen how weather, maintenance, and budget all influence which material stands the test of time. This guide breaks down the key differences between hardwood and composite decking, so you can make a confident, informed choice for your home.
Your dream deck should look stunning today — and still feel solid a decade from now.

What Is Hardwood Decking?
Hardwood decking is made from solid timber planks, often sourced from native Australian species like Spotted Gum, Merbau, Blackbutt, or Ironbark. Each board is naturally unique, with grain variations and rich colour tones that can’t be replicated by synthetic products.
Benefits
- Natural beauty: No two boards are alike — every deck tells its own story.
- Durability: Dense timbers like Spotted Gum and Ironbark naturally resist rot, insects, and heavy wear.
- Restorability: Can be sanded, stained, or refinished multiple times for a fresh look.
- Adds value: Considered a premium outdoor feature that enhances property appeal.
Considerations
- Requires ongoing oiling or sealing to preserve colour and prevent moisture absorption.
- Naturally changes tone over time with sun exposure.
- Costs more upfront and demands regular upkeep.
For those who value authenticity and timeless style, hardwood remains the gold standard in decking.
What Is Composite Decking?
Composite decking is a modern alternative made from a blend of recycled wood fibres, plastics, and bonding agents. It’s engineered for strength, stability, and minimal maintenance — all while imitating the look of natural timber.
Benefits
- Low maintenance: No need for sanding, oiling, or sealing.
- Highly durable: Resistant to fading, warping, and termites.
- Consistent colour: Every board is uniform, ideal for contemporary design.
- Eco-friendly: Made using recycled materials, reducing landfill waste.
Considerations
- Doesn’t have the same warmth or “natural feel” as hardwood.
- Can heat up more quickly in full sunlight.
- Once damaged, boards usually need replacing rather than refinishing.
Composite decking brings convenience, consistency, and sustainability to outdoor living.

Hardwood vs Composite Decking: Quick Comparison
Feature | Hardwood Decking | Composite Decking |
Material | 100% natural timber | Recycled wood & plastic blend |
Appearance | Rich, natural grain | Uniform texture & tone |
Durability | Extremely strong, but weather sensitive | Highly resistant to fading & rot |
Maintenance | Regular cleaning & oiling | Simple washdown, no refinishing |
Lifespan | 25–40 years with care | 20–30 years depending on brand |
Eco Impact | Renewable, biodegradable | Made from recycled materials |
Repairable? | Yes (sand, stain, replace boards) | Limited — damaged boards replaced |
Cost Range | $$–$$$$ | $$$ |
Underfoot Feel | Warm & organic | Cooler, firmer surface |
Both hardwood and composite decks can perform beautifully — the right choice depends on your lifestyle and expectations.
Durability and Weather Resistance
Australia’s climate is tough on decks — scorching sun, heavy rainfall, and coastal humidity all test the limits of your materials.
Hardwood
Natural timber can handle a lot, but it needs protection. Without proper sealing, sun exposure can cause fading and moisture can lead to warping or cracks. Regular oiling keeps hardwood nourished and water-resistant, especially for Sydney’s coastal and hillside suburbs.
Composite
Composite decking is built for endurance. It doesn’t absorb moisture or fade in the sun, making it ideal for pool surrounds, alfresco areas, and beachside homes. The boards don’t splinter or rot, even with minimal maintenance.
For high-exposure or coastal environments, composite often wins on consistency — but hardwood still triumphs in classic beauty.
Maintenance & Long-Term Care
Your deck’s longevity depends on how you care for it. Here’s what to expect from each type:
Hardwood Maintenance
- Sweep regularly to remove dirt and debris.
- Re-oil or seal every 6–12 months to prevent fading and water damage.
- Sand and recoat every few years for a refreshed finish.
- Inspect for nails, splits, or cupping annually.
Pro Tip: Use a soft broom and mild timber cleaner — avoid harsh pressure washers that can damage the grain.
Composite Maintenance
- Simply hose down or mop with mild detergent.
- No need for oiling or staining.
- Resistant to termites and rot, making upkeep minimal.
Composite decking offers a “set and forget” approach, while hardwood rewards those willing to maintain it.
Sustainability and Environmental Impact
Both decking materials can be sustainable choices — it just depends on sourcing.
Hardwood:
When responsibly harvested from FSC-certified Australian forests, hardwood is renewable and biodegradable. It stores carbon and supports local industries.
Composite:
Made from recycled plastics and reclaimed wood fibres, composite decking helps divert waste from landfill. However, it isn’t biodegradable and requires more energy to manufacture.
At AJ Flooring, we prioritise eco-friendly sourcing and long-life performance for every decking project.
Cost and Long-Term Value
Upfront, hardwood decks typically cost more to install due to material and maintenance requirements. However, they can add significant property value — particularly for heritage or luxury homes.
Composite decks offer better long-term cost stability: there’s no need for oiling or refinishing, and warranties often extend 20–25 years.
When considering value, think about total ownership cost — not just installation. Hardwood costs more to maintain, while composite costs more upfront but less over time.
The right choice balances beauty, budget, and the way you use your outdoor space.
Which Decking Is Right for You?
There’s no one-size-fits-all answer — it depends on your home, lifestyle, and design goals.
Choose Hardwood If:
- You love the warmth and character of real timber grain.
- You’re happy to re-oil and maintain your deck.
- You’re renovating a high-end or classic home.
Choose Composite If:
- You prefer a low-maintenance lifestyle.
- You live in a humid or coastal area.
- You like clean, modern design with uniform tones.
