Composite Decking in Perth: Which Brand Actually Performs?

Walk into any decking showroom in Perth and you'll get told whichever composite brand they stock is the best one. Eva-Last reps will tell you Trex fades. Trex reps will tell you Eva-Last gets hot. NewTechWood reps will tell you both of the above. They're all selectively right, which means they're all selectively wrong.

I've installed all three across Perth in the last few years — Eva-Last in Mosman Park, Trex in Applecross, NewTechWood in Subiaco and Cottesloe. They're all good products. They are not interchangeable, and the right answer for your project depends on three things: aspect, board colour, and how often you'll be on the deck barefoot.

This is the honest read on the best composite decking in Perth, brand by brand, with the tradeoffs each one actually has when you live with it.

The short answer

If you want the lowest surface temperature in full Perth sun, NewTechWood capped composite in a light colour leads the field. If you want the most natural timber appearance and the strongest brand warranty, Trex Transcend is hard to beat. If you want the best balance of price, durability, and Australian-developed design for our climate, Eva-Last Infinity is the most defensible all-rounder.

None of the three is the wrong answer. The wrong answer is buying any of them on a poor substructure. Composite decking forgives nothing about a bad frame underneath, and the boards are not the limiting factor in deck lifespan in Perth.

The right composite for your project is decided by aspect (how much full sun the deck gets), colour (dark composite plus full sun equals heat), traffic (kids, dogs, bare feet), and budget.

Eva-Last: the Australian-developed all-rounder

Eva-Last is engineered for Southern Hemisphere conditions, which matters in Perth because most of the testing data behind composite decking comes from North American climates. The Eva-Last Infinity range uses bamboo-polymer composite with a co-extruded cap, and the heat performance numbers in the Perth summer are measurably better than uncapped composites and most older Trex generations.

Pricing in Perth runs roughly $130-$170 per square metre for the boards alone, depending on profile and colour. Installation costs are similar to other composites — composite is composite when it comes to labour, give or take.

Where Eva-Last wins:

Heat performance in light to mid colours is among the lowest in the market
Range of finishes that look reasonably timber-like, particularly in the Apex range
Strong dealer network in WA, with reps who've actually walked Perth installs
Generally available with shorter lead times than Trex during peak demand

Where Eva-Last gets you in trouble:

Dark colours still get hot in full Perth sun. "Cooler than the alternatives" is not "cool"
The bamboo-polymer composition has had occasional batch issues with edge expansion when installed too tight. This is an installer problem more than a product problem, but it's worth noting
The bevelled board profile common in older Eva-Last ranges is fine but starting to look dated next to the cleaner square edges of the newer Trex and NewTechWood profiles

Eva-Last is what we install most often when the client wants a defensible balance of cost, looks, and Perth-suited performance. The answer to "best composite decking Perth" for most homeowners ends up being Eva-Last for these reasons.

Trex: the warranty and the appearance

Trex is the biggest composite brand in the world by volume, and the Trex Transcend range is the most timber-like board on the market. Up close it does a better job than anything else of looking like a stained hardwood. From two metres away most people can't tell.

Trex's 25-year limited residential warranty is the most robust in the industry, and the company has been honouring claims long enough to have a track record. That matters more than people realise.

Pricing in Perth runs $160-$220 per square metre for Transcend boards. Trex Enhance (the lower-end range) sits closer to $120-$150 but the appearance and feel drops noticeably.

Where Trex wins:

Most timber-realistic appearance, especially in Spiced Rum and Tiki Torch finishes
Strongest written warranty and longest track record on warranty claims
Solid heat performance in lighter colours like Havana Gold and Whitewash Cedar

Where Trex falls short:

Premium pricing, particularly for the Transcend range
Lead times in Perth can stretch to 4-6 weeks in peak season, which has cost us schedule slip on a few jobs
Dark Trex Transcend in full afternoon sun in Subiaco hits the same heat range as any other dark composite. The brand premium doesn't change the physics

Trex is what we install when the client specifically wants the timber-look outcome and is prepared to pay for it, or when the warranty is a non-negotiable for the client.

NewTechWood: the heat-resistant outlier

NewTechWood's UltraShield capped composite has the lowest surface temperature performance of the three brands in independent testing, and that holds up in the Perth installs I've measured. On a 38°C day in Cottesloe, light-coloured NewTechWood boards in full sun ran 8-12°C cooler than equivalent dark Eva-Last boards on the same project.

That's the headline. The rest of the story is mixed.

Pricing in Perth runs $120-$170 per square metre depending on range. The Naturale range is the premium tier and looks closer to timber than the lower-end UltraShield boards.

Where NewTechWood wins:

Best heat performance in the category, particularly in light colours
Strong colour retention — fade is among the lowest in the brands I've tracked over 5 years
Competitive pricing, particularly compared to Trex Transcend

Where NewTechWood is harder to recommend:

Appearance gets less timber-like as you go through the range. The lower tiers look noticeably plastic
Smaller distributor footprint in Perth than Eva-Last or Trex, which can mean longer lead times on specific colours
Warranty terms are competitive but the Australian claims track record is shorter than Trex

We install NewTechWood specifically when heat is the priority — pool decks, north-west aspects, full-sun second-storey decks where bare feet matter. It's a strong product for that brief.

Heat: the thing nobody quotes accurately

Every composite brand will give you a heat figure that looks reasonable. They're all measured in slightly different conditions, often with cooler ambient temperatures than a Perth February delivers.

Real-world surface temperatures we've measured on Perth installs in 35-38°C ambient conditions:

Light composite (Eva-Last Pebble, Trex Whitewash, NewTechWood Light Grey): 50-60°C
Mid composite (Eva-Last Apex Steel, Trex Spiced Rum, NewTechWood Walnut): 60-70°C
Dark composite (Eva-Last Apex Black, Trex Lava Rock, NewTechWood Ipe): 70-80°C

For reference, hot car bonnet metal in Perth summer is typically 65-75°C. A dark composite deck in full sun is in that same range. Wear thongs.

If you need bare-feet performance — pool decks, kids — go light. The colour decision matters more than the brand decision for heat. A light-coloured Eva-Last will be cooler than a dark Trex every time.

The honest take

Composite is sold on the wrong story. The brochures emphasise "no maintenance" as the primary benefit, which is technically true but understates the real proposition. The actual benefit of good composite is that it doesn't surface check, doesn't crack, doesn't silver, doesn't need oiling, and looks 90% as good at year 15 as it did at year 1.

The "no maintenance" framing has caused more disappointed clients than any other piece of decking marketing I've seen. Composite still gets dirty. It still needs washing. It can still stain if you spill red wine and leave it for a week. It's lower maintenance than timber by a wide margin, but it's not zero maintenance, and any builder telling you otherwise is selling you a brochure.

The other industry pattern worth calling out: the "best composite decking Perth" question gets answered by whoever paid for the showroom. Eva-Last, Trex and NewTechWood all run dealer networks. The dealer with your local relationship will recommend their stock. That's not corruption — it's just commerce. Read past it.

What to ask any composite installer

If you're getting composite quotes, run these past the builder.

What's the actual brand and exact range, in writing? (Watch for "premium composite" with no brand specified)
What's the substructure spec underneath — joist tape, fixing grade, ventilation gap?
What's the install spacing between boards and what gap is being left at the perimeter?
Have you installed this brand before in Perth, and can I see one at year 3+?
What's the warranty claims process if a board fails — who pays for removal and reinstall?

A real composite installer will have specific answers to all of these. A generalist will hedge. The best composite decking Perth has to offer is wasted on a poor install, and most "composite failures" we see are install failures dressed up as product failures.

Where Endure sits

We install all three major composite brands depending on the project brief. We don't have a preferred-supplier relationship that pushes us toward any one of them. The recommendation we give comes from the project — aspect, colour priority, budget, and how the client uses the deck.

Our composite builds run $850-$1,100 per square metre fully installed depending on brand and substructure complexity. That includes joist tape on every bearer, marine-grade fixings within 5 km of the coast, and engineer-specified footings. The boards are usually 20% of the total cost. The other 80% is what makes the deck last 25 years instead of 12.
