There is no single per-metre price for a Colorbond fence. Height, length, terrain, removal and access are what move the number — this guide walks through each one.
There is no single per-metre price for a Colorbond fence. What sets the figure is fence height, the total length of the run, the ground you're digging into, whether an old fence has to come out first, and how close a ute or excavator can get to the line. Gates and coastal-grade fittings sit on top of that. On the Bellarine, salt air and exposed blocks add their own requirements. An accurate figure comes from an on-site measure, not a calculator.
We fence right across the Bellarine Peninsula and into Geelong, and here's the honest version most price guides skip: two houses on the same Ocean Grove street can quote differently for the same fence. One block is flat sand; the neighbour has a dune fall across the backyard and an old paling fence to demolish first. Same product, same colour, two different jobs.
So when someone asks what Colorbond costs per metre, the accurate answer is that it depends on your block. The rest of this guide walks through each factor that moves the number, so you can read a quote properly instead of just comparing bottom lines.
A Colorbond quote is a sum of separate line items, not one flat rate applied to a length. Once you can see the parts, you can read a quote properly and ask the right questions when a second one lands in your inbox. Here's what moves the number, roughly in the order it matters on the Bellarine.
Height is the biggest single driver. A taller fence needs more sheet steel and taller posts, and because it catches more wind it needs deeper, wider footings to stay put. The residential heights we install most are 1.5 m, 1.8 m and 2.1 m; 1.8 m is standard for side and rear boundaries. Stepping up from 1.8 m to 2.1 m is not a modest bump in material. It changes the footing on every post down the line, and on an exposed coastal block that matters more, not less.
A longer run costs more overall, but it can work out more efficient per metre, because the cost of turning up, unloading and setting out is spread across more fence. The reverse catches people out: a short six-to-eight-metre infill beside a driveway, or a single gate return, often carries a higher effective rate. The gear still has to be loaded, the crew still has to travel, and a hole is a hole whether it's the first or the fiftieth. A proper quote starts from your boundary measured on the ground, not paced off a title plan.
Flat ground is the cheapest fence you'll ever buy. A slope gets handled one of two ways. Either the fence steps down the fall in a run of level panels (think of a staircase in Colorbond), or it rakes on a continuous angle with a sleeper or plinth course along the base to close the gap to the ground. Stepping looks crisp but wastes sheet at each drop; raking keeps the top line clean but adds set-out time. Either way you're buying more material and more labour than a flat run.
This is not an edge case here. Plenty of blocks through Drysdale, Curlewis and Clifton Springs sit on a gentle undulation, and the dune blocks behind Ocean Grove can fall a fair way across a single backyard. If your land isn't level, slope belongs in the conversation early.
If something is already standing on the line, it comes out before a new post goes in. Old paling, rusted sheet, a stretch of wire, or all three spliced together after thirty years of patch jobs: that's demolition time, then loading, then a run to the transfer station or a skip on the nature strip. Older places around Drysdale, Portarlington and Clifton Springs are the slow ones: a fence line that's been added to a panel at a time, with three different post types and concrete footings that fight you on the way out. Removal is quoted as its own line, separate from the new fence, because the effort has nothing to do with what's going back up.
If a machine can reach the line, the holes fly in. If it can't — a 900 mm side gate, garden beds planted hard against the boundary, exposed-aggregate paving you can't crack, a rear yard you can only reach by carrying posts down a side path — then the auger stays on the ute and every hole gets dug by hand. Hand-digging is honest work and slow work, and it shows up in the quote.
What's under the surface matters just as much as what's on top. Coastal sand off the back of Ocean Grove or St Leonards digs easily but won't grip a post on its own. Head inland toward Drysdale and Clifton Springs and you're into heavy clay, with the odd basalt shelf that stops an auger dead. In a dry February that clay sets like concrete; the auger skates, and a hole that takes minutes in winter can take a proper effort in summer. Reactive clay wants more concrete around each post as well, because it swells and shrinks with the seasons and will work a skinny footing loose over a few years.
A gate is a job inside the job. Each one needs its own hinges and latch, and usually a beefier post either side to carry the swing without dropping over time. A pedestrian gate is a small addition; a double driveway gate is a bigger one, and automating it (motor, sensors, a remote or keypad) adds a separate cost again. Gates never fold neatly into a per-metre rate, so a straight quote prices them on their own. See our gates and automation options if a driveway gate is part of the job.
Plain Colorbond is one product, but what you do at the top and bottom changes the job. A plinth course (a solid panel along the base) or a lattice top adds to both the material list and the install time. Coastal-grade fittings are the other variable: heavier-gauge fixings, hinges and cappings rated to stand up to salt. They cost more than a standard fitout on day one and earn it back in years of service on an exposed block. How close you are to the water decides whether that's money well spent or money you don't need to spend.
A shared boundary doesn't change what the fence costs to build. It changes who gets a say in it. Under the Victorian Fences Act 1968, adjoining owners are generally expected to share the reasonable cost of a "sufficient" dividing fence in roughly equal proportions, once the proper notice has been given and the work agreed or determined. That's a cost-sharing arrangement between neighbours, separate from the build itself, and it's a far easier conversation to have with a written quote already in hand.
A fence two streets back from Port Phillip Bay lives in a different world to the same fence ten kilometres inland at Moriac. The postcode doesn't change the price; the specification does. Three things drive that.
Salt-air-rated fittings. Salt in the air eats fixings, hinges and any exposed steel edge faster than standard hardware is built to cope with. You see it first on the small stuff: a latch that seizes, tek screws weeping rust down a panel. Close to the water — Ocean Grove, Barwon Heads, Portarlington, St Leonards — coastal-grade fittings earn their keep. It's the difference between hardware that quietly does its job for years and hardware that's on the replacement list before the fence itself is halfway through its life.
Wind off the water. An exposed block copes with loads a sheltered inland yard never sees. Corner allotments, blocks backing onto open reserve, anywhere with a clear fetch of wind off the bay: the fence acts like a sail, and that lateral load has to go somewhere. Usually that means closer post spacing, extra bracing, or deeper footings so a tall fence doesn't start rocking loose after a couple of rough winters. None of it is optional on an exposed line; it's what keeps the fence standing.
The soil underneath. Coastal sand digs like a dream and holds a post like wet sugar. To get the same grip you'd get from clay, a post in sand wants a wider, deeper footing and more concrete around it. Inland the problem flips: reactive clay swells in winter and shrinks in summer, and a footing that was set too shallow will lever itself loose over a few seasons. Whichever way it goes, the footing gets sized for the soil it's sitting in, which is exactly the kind of thing a national-average calculator can't know about the ground in your backyard.
Colorbond, timber and aluminium sit at different points on the same trade-off: what you pay to put it up versus what it asks of you afterwards.
Treated-pine paling is the cheapest fence to install of the three, and that's its whole appeal. The catch arrives later. Timber wants painting or oiling to hold its look, individual palings cup and split and get swapped out one by one, and posts sitting in wet or reactive soil rot at the ground line well before the top of the fence is tired. Near the coast the salt and the sun speed all of that up. We've pulled out plenty of timber fences on the Bellarine that were technically cheaper to build and turned out dearer to own once you total up two decades of repaints and replaced palings.
Colorbond costs more to install than timber and then asks almost nothing of you. No painting, no oiling, no rot at the base. It holds its colour and stays square for decades with the occasional hose-down, and that's exactly why it's quietly become the default boundary fence across Geelong and the Bellarine over the last generation. If you're staying put, it's usually the one that costs least over the years you actually own it.
Aluminium — the pool fencing, the feature panels, the more open boundary sections — generally sits above standard Colorbond to install, and there's a reason for that. You pay for a lighter, more open look and strong corrosion resistance, so it earns its place where you want to see through the fence rather than block it out, or where a pool safety barrier is the job.
The honest position: there's no fence that's cheapest across its whole life for everyone. If you're selling in three years, upfront price rules. If this is the family home, the fence you're not maintaining in fifteen years is the one that saved you money, and on an exposed coastal block that maths tilts harder toward Colorbond every time.
An online calculator gives you a ballpark and calls it a price. It can't see your soil, your slope, or the rusted-out sheet fence it has to compete with the tip fees to remove. That's why two houses on one street land on different numbers, and why a real quote starts with someone standing on your boundary rather than clicking through a form.
A proper measure means walking the line, reading the ground for soil, fall and obstacles, working out exactly what has to come out before anything goes in, and marking where you want gates. A complete written quote should show you:
