Colorbond and timber paling are the two most popular residential fence types in Australia, and the cost difference between them is smaller than most homeowners expect. The real story is what happens over 10–25 years — and that's where the right choice becomes clear.
Upfront cost comparison
| Cost Factor | Colorbond Steel | Timber Paling |
|---|---|---|
| Installed cost per metre | $85–$140 | $80–$130 |
| Standard suburban fence (30m) | $2,550–$4,200 | $2,400–$3,900 |
| Corner/complex sites | +$200–$500 | +$300–$700 |
| Gate (standard) | $400–$800 | $300–$600 |
| Removal of old fence | $15–$25/m | $10–$20/m |
25-year total cost comparison
Timber looks cheaper upfront but typically requires repainting or restaining every 3–5 years ($600–$1,500 for a 30m fence) and post replacement at year 10–12 ($200–$600 per post). Over 25 years a timber fence can cost 40–60% more than Colorbond in total maintenance.

| Maintenance (paint/stain) | $0 | $3,500–$6,000 |
| Post repairs/replacements | $0–$200 | $1,500–$3,000 |

Frequently asked questions
Is Colorbond or timber cheaper?
Timber is slightly cheaper upfront ($80–$130/m vs $85–$140/m for Colorbond). But over 25 years, Colorbond costs significantly less once you factor in timber's maintenance, repainting and post replacement costs. For a 30m fence, the 25-year cost difference can be $5,000–$9,000 in Colorbond's favour.
How long does Colorbond fence last compared to timber?
Colorbond lasts 40–70 years with minimal maintenance. Timber paling fences last 10–15 years before the posts rot at ground level — typically requiring full replacement. Treated hardwood posts can extend life to 20–25 years but at higher upfront cost.
Does Colorbond add more value to a property than timber?
Generally yes — Colorbond's clean, low-maintenance appearance is preferred by most buyers. A new Colorbond fence is more likely to be noted positively in property marketing than timber, particularly in suburban markets where maintenance-free features are valued.
Can I mix Colorbond posts with timber palings?
Yes — Colorbond steel posts with timber paling infill is a common hybrid approach. You get the durability of steel posts (which won't rot) with the aesthetic of timber. This typically costs $95–$145/m and extends the fence's structural life significantly.
