What a Colorbond Fence Actually Costs in Australia

A standard Colorbond fence installed by a contractor typically runs $110 to $220 per linear metre in 2026, depending on your state, the fence height, ground conditions and how much of an old fence has to come out first. Doing it yourself with the same Lysaght or Stratco sheet-and-post system usually brings the materials cost down to $60 to $110 per metre, but you take on the post holes, cutting sheets to follow a slope, and getting panel spacing right so the fence actually looks straight. Most of the real variation in price comes down to a handful of specific factors that a phone quote rarely covers, so it pays to understand them before you sign anything.

What "per metre" actually buys you

When a fencer quotes a rate per linear metre, that number usually assumes flat, clear ground, a standard 1.8 metre height, posts on level spacing (generally every 2.25 to 3 metres depending on the system), and no removal of an existing fence. It is a baseline, not the final number for your job. A typical suburban block with a rear boundary of 20 to 25 metres and side boundaries totalling 30 to 40 metres can land anywhere from $6,000 to $15,000 fully installed once you add gates, corner posts and any extra bracing.

Materials generally break down as Colorbond sheeting (Custom Orb profile is the standard for fencing), galvanised steel posts and rails or a post-and-panel system, concrete for footings, and fixings. Labour is usually 40 to 55 percent of the installed price, which is exactly why DIY saves so much on paper, provided you have the tools and the time.

The variables that swing the price

Height. Standard is 1.8 metres. Stepping up to 2.1 metres for extra privacy or noise reduction adds cost in steel, sheeting and often in post depth and footing size, since a taller fence catches more wind load. Expect 10 to 20 percent on top of the standard rate.

Sloping ground. Flat, level ground is the cheapest scenario to fence. A sloping block forces a choice between raked (stepped) panels that follow the slope, or stepped fencing with level sections and small drops between them. Raked Colorbond costs more because the sheets need cutting to an angle on site rather than dropping straight in, and post spacing often needs adjusting to keep everything plumb. Steep blocks can add 20 to 40 percent to the per-metre rate.

Removing the old fence. Pulling out an existing timber or ageing Colorbond fence, disposing of old posts set in concrete, and levelling the ground before the new fence goes in is routinely underquoted. Concrete footings from the old posts often need breaking out, or the new posts need to be offset from them, and tip fees for old fencing material add up on a long boundary. Ask whether removal and disposal is included or charged separately, because this is the single most common gap between a phone estimate and the final invoice.

Post spacing and post type. Wider post spacing looks cheaper because it uses fewer posts, but it can flex more in wind and needs a heavier rail or sheet gauge to stay rigid. Steel posts set in concrete are standard; some systems use in-ground steel with no separate rail, others use a post, rail and sheet build. If you are comparing quotes, check that the post spacing is actually the same between them, because a cheaper quote with posts every 3 metres is not directly comparable to one with posts every 2.25 metres.

Sheet fencing vs panel systems. Plain Custom Orb sheet-and-post is the cheapest and most common residential option. Pool-compliant panel systems, which need to meet climbability rules under AS1926.1, generally cost more per metre because of the certified gap requirements and hardware, and acoustic or heavier-gauge Colorbond for busy roads adds further again. If you are fencing a pool area, factor in that compliance cost from the start rather than after a failed inspection, and see how the rules interact with boundary and height limits in our guide to fence height and boundary rules across Australia.

DIY vs paying a contractor

Colorbond is genuinely one of the more DIY-friendly fencing systems because it is a bolted or screwed sheet-and-post kit rather than something requiring specialist trade skills, and hardware chains and specialist fencing suppliers sell the components individually. Realistic DIY savings are 40 to 55 percent of the installed price, mostly labour. What you are trading for that saving is your own time (a 25 metre run is a solid weekend or two for two people), the physical work of digging and setting posts in concrete, and the risk of getting spacing or levels wrong on a long or sloping run, which is expensive to fix once the concrete has gone off.

Buying second-hand or surplus Colorbond sheeting and posts through a local marketplace is a genuine way to cut materials cost further, provided you check the sheets are not corroded at the cut edges and the profile matches what you need. Browse current Colorbond and steel fencing listings or list your own leftover materials if you have offcuts from a finished job by selling on the marketplace.

What a fair written quote itemises

A quote scrawled on the back of a business card is not a quote you can hold anyone to. A proper written quote should itemise:

• Total linear metres and the rate per metre, broken down by any different heights or sections
• Whether removal and disposal of the existing fence is included
• Post spacing, post gauge and footing depth
• Number and type of gates, including hardware
• Whether the price includes GST
• A start date and expected completion timeframe
• Payment terms, including any deposit

If a quote is missing most of these, ask for them in writing before you commit. Fencing sits on a shared boundary in most suburban settings, and if you are replacing a fence your neighbour also benefits from, the cost-sharing rules are worth understanding before work starts. Our state-by-state breakdown of who pays for the fence under dividing fence rules covers what you can reasonably ask a neighbour to contribute.

Getting it right the first time

The cheapest quote is not always the cheapest fence once you account for a rushed job that needs redoing, undisclosed removal costs, or posts set too shallow for the local wind zone. Get at least two written quotes, confirm what is and is not included, and if you are unsure whether Colorbond is even the right call for your block compared with timber, our comparison of timber versus Colorbond fencing walks through cost, lifespan and maintenance side by side. For rural boundaries needing wire and posts rather than sheet fencing, check rural stock fencing supplies instead, since the pricing and materials involved are a different exercise entirely.

A last practical note: prices above are typical ranges seen across metro and regional markets in 2026, not a fixed national rate. Freight to regional and remote areas, local labour availability, and council permit fees where they apply will all shift the final number, so treat every figure here as a starting point for your own written quotes rather than a guarantee of what your job will cost.
