Security and Privacy Fencing: Costing a Fence That Does a Job

By the WTD team · Updated June 2026

What's The Damage's July 2026 re-verification across 90+ sources spans the full fencing range — from chain-link and wire at $30–$90 per metre to picket at $100–$250 and solid privacy screens well beyond. The gap isn't just material; it's what you're asking the fence to do. Here's how to cost a fence built for privacy or security rather than a plain boundary line.

What "purpose" does to the price

A boundary fence just marks the line. A privacy or security fence is asked to do a job — screen a yard, keep something in or out, slow an intruder — and that job, not the material alone, sets the cost. The full fencing range shows how wide the gap gets.

Chain-link and wire sit at the bottom at $30–$90 a metre — see-through, functional, ideal where you need containment or a boundary but not concealment. Picket runs $100–$250 a metre — charming and defining, but deliberately open, so it does nothing for privacy. Solid privacy screens climb well beyond both. The lesson is that you're not buying fence by the metre so much as buying a level of screening and strength, and the two goals — privacy and security — pull the design in different directions.

Privacy: height and infill do the work

Privacy is a function of two things: how tall the fence is, and how completely it blocks the view through. Height is the first lever, and it runs straight into the council rules — a privacy fence usually wants to sit at the top of the permitted boundary height, so the height limit for your boundary effectively caps how much privacy a fence can buy before approval is needed. Infill is the second: a solid sheet screens completely, closely spaced boards screen almost as well while letting some air through, and a slatted or lattice-topped design trades a little screening for a lighter look and better airflow. The more completely a fence blocks the view and the taller it stands, the more material and structure it needs, and the further up the range it lands. A privacy fence is essentially a wall you're allowed to build to the boundary limit, and it's priced like one.

One frequently overlooked factor: a tall solid fence catches wind like a sail, so it needs stronger posts set deeper and, on exposed sites, closer together. That structural upgrade is part of why a solid privacy fence costs well more than an open one of the same height — you're paying for what holds it up as much as what you see.

Security: strength, height and access

Security fencing optimises for something different — deterrence and delay. Where a privacy fence hides, a security fence resists. The cost drivers are height (tall enough to be hard to climb), strength (materials and fixings that resist being cut, bent or pushed through — which is where sturdier steel and welded construction come in over light wire), a hard-to-scale top (smooth or pointed rather than a helpful foothold), and controlled access, since a strong fence is only as secure as its weakest gate. A genuinely secure boundary usually pairs a robust fence with a solid, well-hung, lockable gate — the two are a system, and skimping on the gate undermines the fence. Security fencing tends to sit in the mid-to-upper range because it's built to take force, not just to stand there.

Where cheap wire earns its place

The bottom-of-range option isn't a poor choice — it's the right choice for specific jobs, and knowing when saves real money. Chain-link and wire at $30–$90 a metre are excellent for containing a dog or children in a back yard, marking a rear or side boundary that doesn't need screening, fencing a large or rural area where solid fencing would be wildly expensive over the distance, or as a secure-but-visible barrier where you want to see through. Where they don't deliver is privacy — they hide nothing — so using wire to screen a yard is the wrong tool, just as using a premium privacy screen to contain a dog on a back boundary is money spent on concealment you didn't need. Matching the fence to the actual job is the single biggest saving available.

Features worth paying up for

Within a privacy or security build, a few upgrades genuinely earn their cost while others don't. Worth it: stronger posts and deeper footings on any tall or solid fence, because the fence lives or dies on its structure; quality gates and locks on a security fence, the weak point that decides everything; and durable, low-maintenance materials where the fence is long or hard to access, since re-doing a big fence is dear. Less worth it: premium finishes on a fence whose whole job is a rear boundary nobody sees, or maximum height where the council limit or the actual need doesn't call for it. The disciplined approach is to spend on the structure and the access — the parts that make the fence do its job and last — and to resist paying for screening or strength beyond what the purpose requires.

When you need both at once

Plenty of fences have to do both jobs — screen the yard and resist an intruder — and the good news is that the two goals overlap more than they conflict. A tall, solid privacy fence is already most of the way to a security fence: height that hides is also height that's hard to climb, and a solid face gives no foothold and no view in for someone sizing up the property. The gap between the two is usually in the details rather than the whole build. To take a privacy fence the rest of the way to secure, you strengthen the structure and fixings so it can't be easily pushed through or pried apart, make sure the top offers no easy grip, and — most importantly — treat the gate as seriously as the fence, with a solid, well-hung, lockable design, since a strong screen with a flimsy gate is neither private nor secure for long.

Where the goals do pull apart is airflow and cost. Complete privacy wants a solid barrier, but a solid barrier catches wind and needs the stronger, deeper posts covered earlier, which lifts the price; a security fence that doesn't need to screen can sometimes be more open, cheaper to build and easier to see through — which some owners prefer, because being able to see out is its own kind of security. So the practical question is which goal leads. If privacy leads, build the solid screen properly and add the security details to it. If security leads and privacy is secondary, a robust but partly open fence may cost less and suit better. Deciding the priority before you quote stops you paying for maximum privacy and maximum strength everywhere when your boundary only needs one of them in most places.

Costing it properly

Start from the job, not the catalogue. Decide whether you're buying privacy, security, containment or just a boundary, because that sets which end of the $30-to-hundreds-per-metre range you're in before any material is chosen. Confirm the height your boundary allows, since that caps what a privacy fence can achieve without approval. Then get quotes that specify the posts and footings, not just the panels — on tall and solid fences the structure is where quality and cost really differ, and a suspiciously cheap privacy-fence quote is usually one built on posts too light for the wind it'll catch. Buy the fence that does your specific job well, put the money into what holds it up and what controls access, and you'll pay for performance rather than for metres.

Frequently asked questions

How much does a privacy fence cost?

It depends on height and how completely it screens, but privacy fencing sits well above open styles. For reference, chain-link and wire run $30–$90 per metre and picket $100–$250, while solid privacy screens climb beyond both. You're really buying a level of screening and structure rather than metres — the taller and more solid the fence, the more material and stronger posts it needs, and the higher it lands.

What makes a privacy fence more expensive than a normal one?

Two things: height and infill. A privacy fence wants to sit at the top of the permitted boundary height and block the view completely, which takes more material. Just as important, a tall solid fence catches wind like a sail, so it needs stronger posts set deeper — and closer together on exposed sites. That structural upgrade is a big part of why a solid privacy fence costs well more than an open one of the same height.

What's the difference between a privacy fence and a security fence?

They optimise for different things. A privacy fence hides — height and solid infill to block the view. A security fence resists — height that's hard to climb, strong cut-resistant materials and fixings, a hard-to-scale top, and controlled access. A secure boundary pairs a robust fence with a solid, lockable, well-hung gate, since the fence is only as secure as its weakest point. Security builds tend to sit mid-to-upper range because they're made to take force.

When is cheap wire or chain-link the right choice?

When you need containment or a boundary but not concealment. At $30–$90 per metre, wire and chain-link are ideal for keeping a dog or kids in a back yard, marking a rear or side boundary, fencing a large or rural area where solid fencing would be hugely expensive over the distance, or as a see-through barrier. Where they fail is privacy — they hide nothing — so using wire to screen a yard is the wrong tool for the job.

Which fencing upgrades are actually worth paying for?

Spend on structure and access: stronger posts and deeper footings on any tall or solid fence, quality gates and locks on a security fence, and durable low-maintenance materials where the fence is long or hard to reach. Less worth it: premium finishes on a rear boundary nobody sees, or extra height beyond what the council limit or the actual need calls for. Put the money into what makes the fence do its job and last.

How do I keep a privacy or security fence quote honest?

Make sure it specifies the posts and footings, not just the panels — on tall and solid fences the structure is where quality and cost really differ, and a suspiciously cheap privacy-fence quote is usually built on posts too light for the wind it'll catch. Decide the fence's job first so you're pricing the right end of the range, confirm your boundary's height limit, and compare quotes on the same structural spec.
