Why Timber is a Great Choice for Aussie Backyards
More and more Australians are looking for backyard renovations and DIY solutions every year. In fact, according to Otto Media the number of searches for outdoor furniture & living content has seen a major boost post-COVID-19 as homeowners are realising just how important it is to maximise comfort in their own home.
Timber is so popular because it’s timeless. It can be adapted to any backyard style, whether that’s rustic and natural, or something more sleek and modern. It’s strong, it’s versatile, and it’s easy to work with. You get the best of both worlds with timber – form and function.
The CSIRO confirms that different timbers vary significantly in their durability and resistance. This makes choosing the right species of timber with your landscaping plans is vital.
Choosing the Right Timber for Outdoor Use
Not all timber is created equal. Some types are better suited for outdoor use than others. Here’s a quick breakdown:
Treated Pine
Treated pine is one of the most popular choices for outdoor timber projects. It's budget-friendly, lightweight and, when treated properly, it’s resistant to termites and rot. It’s great for fencing, play equipment, planter boxes, and garden edging.
Merbau
Merbau is a dense hardwood that’s naturally resistant to decay and insects. You’ll often see it being used for decking and outdoor furniture, given its durability and gorgeous colour. The only downside is the risk of natural staining (tannin), so sealing Merbau properly is a must!
Spotted Gum
This Aussie native is perfect for structural timber applications. It’s strong, beautiful, and holds up well in exposed environments like pergolas, decks, or outdoor play equipment.
Cypress Pine
Cypress pine is termite-resistant and emits a natural scent that repels pests. It’s often used for pergolas and outdoor framing, as well as sandpits & mud kitchens.
What to Consider Before You Choose
-
Use: Is it for sitting, playing, or standing? For example, furniture and cubby houses will need a smooth, splinter-free timber.
-
Exposure: Timber exposed to full sun and rain needs to be durable!
-
Budget: While treated pine is more affordable, more expensive hardwoods are longer-lasting.
In your search for timber, choosing the right species and grade is vital. Reach out to reputable timber suppliers, like Pinus Sawmills, to make sure you’re investing in high-quality outdoor-grade products fit for your exact backyard project needs.
Bonus: The Australian Timber Database provides in-depth species profiles, including performance ratings, making it a useful tool for backyard DIYers.
Sealing and Maintaining Timber in Australian Conditions
Australia’s weather can be brutal. Intense sun, heavy rain, humidity, frost. You name it. Australia’s got it. These factors take a real toll on unprotected timber. That’s why sealing and regular maintenance are musts!
How to Seal Outdoor Timber
-
Start with a clean surface: Use a timber cleaner and lightly sand the surface to remove dirt and old coatings.
-
Choose the right sealant: Look for an exterior-grade oil or water-based sealant. Oils penetrate the timber, while water-based sealers provide surface protection.
-
Apply evenly: Use a brush or roller and apply two thin coats. Make sure the timber is dry before starting.
-
Reapply annually: Aussie sun will wear down any finish. A yearly recoat keeps timber looking fresh and protected.
Extra Tips for Timber Longevity
-
Try to keep furniture up and off the ground to stop water from entering and weakening the timber.
-
Use rust-proof hardware to avoid staining or weakening the timber.
-
Check for splinters or cracks in kids' play equipment every few months to be safe.
-
Keep it clean. Dirt and leaves trap moisture, which can lead to the timber decaying.
Bonus: The Queensland Government’s Building Guidelines provide detailed advice on sealing and maintaining exterior timber structures.

Treated pine is a popular choice because it’s a great middle point between cost and quality. Aka, getting the best product for the best price! Remember though, your timber needs proper sealing and care to avoid things like weathering, splintering and rot.
