Quick Answer
Colorbond steel fencing wins on longevity (25–30 years with minimal maintenance) and is better suited to Melbourne’s coastal areas, windy SE suburbs, and termite-prone zones. Timber fencing costs less upfront ($80–$120/m installed vs $95–$160/m for Colorbond) and looks warmer, but needs repainting or oiling every 3–7 years and is vulnerable to termites and rot in Melbourne’s clay-heavy south-eastern suburbs. For most new fences in SE Melbourne, Colorbond offers better long-term value.
Choosing a new fence in Melbourne involves more than just looks. Termite pressure in Berwick, Cranbourne, and Pakenham, the salt air exposure in Frankston and Mornington, and the wind loading in Officer and Pakenham all affect which material holds up better over time. This comparison uses 2026 Melbourne installation prices and accounts for 20-year total cost of ownership.
Cost Comparison: Timber vs Colorbond (Melbourne 2026)
| Cost Factor | Timber Paling Fence | Colorbond Steel Fence |
|---|---|---|
| Supply and install (per linear metre) | $80–$120 | $95–$160 |
| Supply only (per linear metre, DIY) | $40–$60 | $60–$90 |
| Typical 30m fence installed | $2,400–$3,600 | $2,850–$4,800 |
| First repaint/re-oil (Year 4–7) | $600–$1,200 | $0 (none needed) |
| Post replacement (10 years) | $200–$600 (common) | Rare — steel posts rarely fail |
| Expected lifespan | 12–20 years | 25–30+ years |
| 20-year total cost (30m fence) | $5,000–$8,000 | $3,000–$5,500 |
Durability and Maintenance
Timber Fencing Maintenance Requirements
Hardwood palings (merbau, spotted gum, or treated pine) need attention every 3–7 years depending on exposure. Posts embedded in Melbourne’s clay soil — which stays wet through winter in Berwick, Narre Warren, and Cranbourne — are particularly vulnerable to rot at the base. Termite pressure adds additional risk in outer SE suburbs where homes back onto bush reserves. Expect to repaint or re-oil the fence every 5–7 years, and plan for at least one or two post replacements over a 15-year fence lifespan.
Colorbond Maintenance Requirements
Colorbond steel fencing requires almost no maintenance in Melbourne’s inland suburbs. The painted steel is factory-coated with BlueScope’s Activate technology and backed by a 10-year warranty from BlueScope. In coastal suburbs like Frankston, Mornington, and Seaford — within about 1km of salt air — the fence should be hosed down twice a year to remove salt deposits that can accelerate corrosion at cut edges. Posts are set in concrete and should last the fence’s full lifespan without replacement.
Appearance and Style
Timber fencing has a warmer, more natural aesthetic that suits older-style homes and gardens with established plants. The texture of hardwood palings is distinctive and provides a good backdrop for climbing plants, hedges, and garden beds. Colorbond comes in 22 standard colours including Woodland Grey, Ironstone, Night Sky, and Evening Haze — all of which complement the brick veneer and rendered homes common in SE Melbourne. Newer homes in Officer, Pakenham, and Clyde North very commonly use Colorbond, giving these estates a consistent streetscape appearance.
Termite Risk: A Critical Melbourne Factor
Colorbond fencing is fully termite-proof. This is a significant advantage in termite-active areas, where even H4-treated timber can be attacked over time if the post treatment is compromised. A termite inspector will also note that a Colorbond fence provides no food source that draws termites toward the house structure.
Privacy and Height
| Factor | Timber | Colorbond |
|---|---|---|
| Standard height | 1.8m | 1.8m (or 2.1m with optional top rail) |
| Privacy (no gaps) | Good (gaps at palings may appear over time) | Excellent (no gaps between sheets) |
| Wind loading (coastal/exposed) | Moderate — gaps reduce sail effect | Higher sail effect — needs correct post spacing |
| Noise reduction | Moderate | Slightly better — dense steel sheet |
| Light penetration | Some (gaps between palings) | None (solid sheet) |
Council Regulations and Permits
In most Melbourne councils, side and rear fences up to 2.0m high do not require a planning permit. Front fences facing a street have lower limits — typically 1.2m or 1.5m depending on the council. Check with your local council (Casey, Cardinia, Frankston, Mornington Peninsula) before installing any fence higher than 1.2m on a street frontage. Neighbour consultation under the Fences Act 1968 (Victoria) is required before installing a new shared boundary fence — even if you’re paying for it yourself.
Top 10 Tips and Gotchas
- Merbau is popular but requires oiling every 3–5 years or it greys and cracks. CCA-treated pine is cheaper but turns green and also needs coating.
- Colorbond Ironstone and Woodland Grey hide dirt and water marks better than lighter colours like Surfmist or Evening Haze — a practical consideration for fences near soil or garden beds.
- Under the Victorian Fences Act, a neighbour can be required to contribute 50% to a replacement fence if the existing fence is beyond its useful life. Get a solicitor’s letter if they refuse.
- Concrete footings are non-negotiable in clay soil. Clay swells and shrinks seasonally — dry summers in Berwick and Cranbourne cause clay to pull away from posts, leaning or toppling fences with inadequate footings.
- Get at least three quotes. Timber fence prices vary enormously by timber species and post size. Colorbond quotes vary by post gauge and sheet profile — “trimline” vs “monoline” profiles look different and are priced differently.
- Don’t assume the existing fence is on the boundary. Boundary surveys cost $800–$1,500 but can save expensive disputes if you build on your neighbour’s land.
- Colorbond posts must be set in concrete a minimum of 600mm deep (800mm in exposed/windy locations like Officer or exposed coastal areas) to meet AS 1684 structural requirements.
- Timber posts should be H5-treated (not H3 or H4) in areas with high moisture or termite activity — H5 is the correct treatment for in-ground timber in high-risk Victorian locations.
- Pool fencing has entirely different rules. Pool fencing must comply with AS 1926.1, regardless of material, and requires council inspection and a certificate of compliance.
- A fence on a slope requires additional planning. Colorbond panels step in fixed increments; timber can be cut to follow the ground. A sloped block may actually suit timber better aesthetically.

Frequently Asked Questions
Does Colorbond fencing rust in Melbourne’s coastal areas?
Colorbond steel is coated with a zinc-aluminium alloy (Zincalume) and a factory-applied paint finish designed for Australian conditions. In coastal areas within 1km of the ocean — Frankston, Mornington, Seaford — hose the fence twice a year to remove salt deposits, particularly at cut edges and screws. With this basic care, Colorbond fencing performs well in all Melbourne coastal suburbs. BlueScope also offers “Colorbond XRW” (Extra Resistance to Weather) for high-corrosion applications.
Which timber species is best for Melbourne fencing?
Merbau (Class 1 hardwood) is the most popular premium choice — durable, attractive, and naturally resistant to rot. CCA-treated pine (H4 in-ground) is the standard budget choice. Spotted gum and ironbark also perform well. Avoid plantation pine without treatment in the ground — it will rot within 5 years in Melbourne’s clay soil. Whatever species you use, ensure in-ground posts are H4 or H5 treated, not just surface-coated.
How do I get my neighbour to share the cost of a new fence?
Under Victoria’s Fences Act 1968, owners of adjoining properties share equally in the cost of an adequate fence. If your neighbour refuses, you must serve them a Fencing Notice (available from Consumer Affairs Victoria) that details the proposed work and cost split, and allow 30 days for them to respond or object. If they still refuse, the matter can be heard at VCAT. Consumer Affairs Victoria has a free guide and template notices on their website.
Can I install a Colorbond fence myself?
Yes, Colorbond fencing is a common DIY project for homeowners with basic construction skills. BlueScope provides installation guides, and pre-cut panel kits are sold at Stratco and Bunnings. The main challenge is setting posts correctly in concrete — uneven post heights or posts out of plumb will be visible in the finished fence. For a shared boundary fence, note that any work in Victorian law also involves your neighbour, so discuss the project with them first.
Is timber or Colorbond better for a fence on a sloped block?
Timber is generally easier to install on a sloped block because individual palings can be cut to follow the ground contour, creating a smooth slope-following bottom edge. Colorbond panels come in fixed height increments and step in 150–300mm jumps, which can leave a gap under the fence on steeper slopes. This gap can be filled with Colorbond infill panels, but it adds cost. For blocks with gradients over 10%, get quotes for both and ask how each contractor handles the slope.
