Colorbond Fencing in Sydney: Costs, Colours and What to Expect
Updated: 3 days ago
Colorbond is the fence most Sydney homeowners end up choosing for a back or side boundary, and for good reason: it goes up quickly, it never needs repainting, and it copes with a coastal climate better than most timber. This guide covers what a Colorbond fence actually involves, what drives the price, and what to check before you sign a quote.
What a Colorbond fence is made of
Colorbond is pre-painted steel made in Australia. A Colorbond fence is a system rather than a single product: steel posts set in concrete footings, top and bottom rails, and vertical steel sheets that slot between them. The colour finish is baked on at the factory rather than applied on site, which is why a Colorbond fence does not need the repainting or re-oiling cycle that a timber paling fence does.
Standard residential heights run from around 1.2m for a front boundary up to 1.8m or 2.1m for a rear or side boundary. Panels can be stepped or raked to follow a sloping block, which matters on a lot of Sutherland Shire and St George backyards where the fall across a boundary is significant.
Why it suits Sydney conditions
No gaps between palings, so you get full privacy from day one.
Termites and timber rot are not a factor, which removes the most common reason older Sydney fences fail early.
No painting, staining or oiling maintenance over the life of the fence.
Steel sheets held in a post-and-rail system move less in wind than individual palings, so you get fewer loose boards after a storm.
Available in a wide range of colours, so a new fence can be matched to an existing roof, gutters or garage door.
The main trade-off is appearance. Colorbond reads as a modern, clean boundary. If you want the warmth of natural timber, particularly on a front fence in a period streetscape, timber is usually the better choice. We compare the two in detail in Colorbond vs timber fencing for a Sydney home.
What drives the cost of a Colorbond fence
There is no single price per metre that holds across every Sydney job, because the site usually decides the cost more than the materials do. The main variables are:
Total length and the height of the fence.
Ground conditions. Sandstone and rock shelf are common across much of Sydney and slow post holes down considerably.
Slope, and whether panels need to be stepped or raked to follow it.
Removal and disposal of the existing fence, if there is one.
Site access. A backyard reachable only through the house or down a narrow side path takes longer than one with rear lane access.
Gates, including the width, the hardware and whether the gate needs to be self-closing.
Retaining. If the boundary needs a low retaining wall before a fence can sit on it, that is a separate piece of work.

Sharing the cost with your neighbour
In NSW, a fence on the boundary between two properties is a dividing fence, and the Dividing Fences Act 1991 sets out how adjoining owners share the cost of a sufficient dividing fence. In practice this means talking to your neighbour before any work starts and agreeing on the type, the height and the cost split, ideally in writing. If you cannot reach agreement, NSW Fair Trading and the Community Justice Centres publish guidance on the formal notice process. Sorting this out early removes the single most common cause of delay on a fence replacement.
Approvals and pool fencing
Most standard residential boundary fences in NSW can be built without development approval, but there are real exceptions: heritage conservation areas, front fences above a certain height, and corner blocks where council applies sight-line rules. Check with your local council before ordering materials rather than after.
A fence that forms any part of a swimming pool barrier is a different matter. Pool barriers in NSW have to comply with the requirements under the Swimming Pools Act and the relevant Australian Standard, which govern height, gaps, the non-climbable zone and self-closing, self-latching gates. Colorbond can form part of a compliant barrier, but the detailing and the gate hardware are what determine whether it passes inspection.
What to check before accepting a quote
That the contractor holds a current NSW contractor licence you can verify yourself.
Whether removal and disposal of the old fence is included or excluded.
Footing detail, including post depth and concrete, not just the fence height.
Whether gates, hardware and delivery are itemised or bundled into a single figure.
Who is responsible for locating underground services before digging begins.
