Fence Cost in Adelaide — Colorbond vs Timber

Fences are usually the last item on a landscaping job and the one homeowners forget to budget for. Adelaide pricing depends on material, height, and access. Here’s what each option costs in 2026.

Quick numbers (per linear metre supplied + installed)

Fence type	1.8m height	Lifespan
Treated pine paling	$90–$140	12-18 years
Hardwood paling	$130–$200	20-30 years
Colorbond	$100–$150	25+ years
Aluminium slat	$180–$280	30+ years
Glass pool fencing	$250–$450	25+ years
Brick + render	$400–$700	50+ years

A typical 30m boundary fence in Colorbond: $3,000–$4,500. The same in hardwood: $3,900–$6,000.

Colorbond — the volume choice

Steel sheets in a range of colours. Quick to install, low maintenance, good lifespan. Available in standard heights (1.5m, 1.8m, 2.0m) and a range of profiles (Original, Smartline, Goodneighbour with no exposed rails one side).

Strengths: termite-proof, fire-resistant, low maintenance, modern look. Weaknesses: dents (kids’ balls, branches), can rust at cuts if not properly trimmed, looks industrial in heritage settings.

Adelaide-popular colours: Surfmist (off-white), Monument (deep charcoal), Woodland Grey, Basalt (mid-grey).

Timber paling — the traditional choice

Treated pine ($90–$140/lm) or hardwood ($130–$200/lm) palings on H4 posts and rails. Cheaper upfront for treated pine; longer-lasting for hardwood.

Strengths: warmer aesthetic, easy to repair plank-by-plank, can be stained or painted. Weaknesses: requires periodic maintenance (oiling/staining/painting), termite vulnerability, eventual replacement.

Common in heritage Adelaide suburbs and family backyards. Hardwood lasts a generation; treated pine needs major work at year 15.

Glass pool fencing — for pools only

By Australian Standard 1926, swimming pools need a fence with specific properties. Frameless glass is the premium option ($350–$450/lm); semi-frameless ($250–$350/lm) is more common.

What’s included: 12mm toughened glass panels, stainless 316 fittings, self-closing gate, latch above 1.5m.

Compliance certification typically $150-$250 from a council-approved inspector — required.

Aluminium slat — modern minimalist

Increasingly popular for front yards and feature fences. Powder-coated aluminium slats on a steel frame. Looks contemporary, allows airflow, doesn’t dominate the streetscape.

Costs more than Colorbond but suits modern homes where Colorbond would feel utilitarian.

What pushes cost up

• Sloping ground — stepped fences need more posts; raked fences need custom panels
• Old fence demolition — $20–$40/lm to remove and dispose
• Access — wheelbarrow-only access adds $10–$20/lm
• Council requirements — some heritage zones restrict materials; pool fencing has compliance overhead
• Footings on rock — Adelaide Hills properties often hit rock and need core-drilling

Council and neighbour considerations

In most South Australian councils:

• Fences under 2.1m on a boundary don’t require development approval (some heritage zones excepted)
• Pool fences must comply with AS 1926 and require compliance certification
• Boundary fences are governed by the Fences Act 1975 — neighbour contribution typically 50/50 for a “sufficient” fence

If you’re replacing a shared boundary fence, talk to the neighbour first. Most disputes come from one party doing the work and asking for contribution after.

Common mistakes

• Skimping on posts. Cheap quotes use 75×75mm posts where 90×90mm is standard. Wind loading on a 1.8m fence stresses the post.
• Concrete-only post footings. Should be concrete plus depth — typically 600-750mm in Adelaide soil.
• Wrong rails. Top + bottom rails are a 2-rail fence; for 1.8m+ a 3-rail fence is more rigid.
• Skipping the gate kerb. A gate without a sill drops over time and binds against the latch.

Maintenance

• Colorbond: rinse annually, touch up scratches with manufacturer’s paint pen.
• Timber: oil or stain every 2-3 years for hardwood; treated pine often left to weather.
• Glass: clean glass every 2-3 months (it shows water spots fast).
• Aluminium: rinse annually.
