Building a deck enhances your outdoor spaces, creating a functional and beautiful area for relaxation or entertainment. Selecting the best timber for your decking project requires careful consideration of durability, cost-effectiveness, appearance, and maintenance.
We look at the different types of decking wood, their pros and cons, and how to choose the right materials for your outdoor decks. Whether you’re looking for hardwood decking, softwood decking, or alternatives like composite timber, this article provides all the essential details.
Why The Type Of Timber Matters
The right timber will give you durability, good looks and low maintenance costs. Wood types vary in durability, weather resistance and appearance so you need to match the material to your climate and intended use.
For example some timbers like spotted gum and jarrah are very durable and are perfect for outdoor use in harsh climates. Choosing the wrong one could mean warping, splitting or termite damage.
What to Consider When Choosing Decking Wood
Before you buy decking materials consider the following:
- Durability: Look for Australian hardwoods or pressure-treated pine which resist rot, warping and insect damage. These are great for above ground use. Of all the hardwoods teak stands out for its durability and ease of use.
- Appearance: Consider colour and texture. Teak and jarrah offer rich dark browns and attractive markings while pine decking has a lighter more rustic look.
- Cost: Softwoods like treated pine are a budget option. They are cheap and widely available.
- Maintenance: All wood requires maintenance but hardwood decking requires regular oil and staining to keep its natural colour and durability.
- Climate Suitability: For bushfire prone areas in Western Australia consider timbers with a high BAL rating like spotted gum which are also fire resistant.

Hardwood decking is known for its durability, good looks and weather resistance. A jarrah deck is a premium hardwood option with many colours and a sophisticated look. It’s also very durable, fire resistant and long lasting if maintained properly so it’s a popular choice for homeowners looking for quality timber decking. Here are some of the most popular hardwood options:

Wooden Deck Maintenance Tips
Proper care extends the life and look of your deck. Follow these:
- Cleaning: Use soap and water to remove dirt and mildew. Pressure wash for deeper clean.
- Sealing: Apply water resistant sealant every year to protect from moisture and UV.
- Staining: Use a good stain to enhance the wood’s natural colour and wear.
- Regular Oiling: Required for hardwood decks like teak or spotted gum to maintain finish.
- Inspection: Check for rot, splintering or loose nails and fix ASAP.
Water Protection
Water protection is key to extending the life of your deck and prevent damage. Water can get into the wood and cause it to expand and contract and lead to rot, decay and even mold and mildew. To protect your timber deck from water damage try:
- Regular Inspections: Check your deck frequently for water damage or leaks. Early detection can prevent minor issues from becoming major problems.
- Proper Sealing: Make sure your deck is sealed with a good quality waterproof sealant. This will create a barrier that prevents water from getting into the wood.
- Cleanliness: Keep your deck clean and debris free. Leaves, dirt and other materials can trap moisture and lead to rot and decay.
- Waterproof Membranes: Install waterproof membranes or flashing around areas where water tends to collect like around posts or railings. This extra layer of protection will reduce water damage.
- Water-Repellent Treatments: Apply water repellent treatment to your decking timber. These treatments will protect the wood from the elements and extend its life.
By doing these you can protect your deck from water damage and have it safe and functional for years to come.
Get Decking Timber from Reputable Suppliers
When it comes to getting decking timber, choosing a reputable supplier is key to get good quality materials. Here are some tips to find and evaluate suppliers:
- Research and Reviews: Start by researching local suppliers and reading reviews from other customers. This will give you an idea of their reputation and material quality.
- Sustainable Practices: Look for suppliers that offer sustainable timber and practice responsible forestry. This is good for the environment and your decking wood’s longevity.
- Options: Make sure the supplier has a variety of timber species and options available, including Australian hardwoods and composite decking. A wider selection means you can choose the best decking material for you.
- Transparency: Check if the supplier provides clear information about the timber’s origin, grade and quality. Transparency is a good sign of a reputable supplier.
- In-Person: If possible visit the supplier’s showroom or warehouse and see the timber in person. This will allow you to inspect and make a decision.
By getting decking timber from a reputable supplier you can have your deck built with good quality materials that will last for years to come.
Budget and Cost for Timber Decking
When planning a timber decking project budgeting is key. Here are some tips to help you manage costs:
- Set a Budget: Determine your overall budget for the project including the cost of materials, labor and any necessary permits or inspections.
- Compare Prices: Research different types of timber decking and compare prices. Treated pine is more budget friendly while hardwoods like jarrah and spotted gum are more expensive but more durable.
- Maintenance Costs: Consider the long term maintenance costs. Hardwood decking will need regular oil and stain while composite decking needs minimal maintenance.
- Value Add: Think about the long term value of your deck. A good deck will add to your outdoor space and increase the value of your home.
- Extras: Factor in the cost of any extras or upgrades like lighting, railings or custom designs. These will add to the cost but will also add functionality and style to your deck.
By considering these costs you can create a budget for your timber decking project that suits you and your budget.
What Wood to Choose – Final Points
Choosing the right wood depends on the decking area, your budget and the local climate. Hardwood decking like jarrah and spotted gum is best for high durability and above ground applications. If on a budget treated pine is a cost effective option. If low maintenance and sustainability is your priority then composite decking is the way to go.
Choosing the right decking wood for your outdoor deck requires consideration of timber species, costs and durability. Australian hardwoods like spotted gum and jarrah are popular for their durability and fire resistance. For budget options treated pine and other hardwoods like merbau are versatile. Composite timber is low maintenance and eco friendly. By assessing your outdoor space, climate and budget you can choose the best decking timber for your new deck.
