If your boundary is protecting stock, tools, your plant or a site you can't watch around the clock, a standard fence isn't enough on its own. Sharkguard™ anti-climb fencing fits along the top of your existing security fencing panels, hardening the fence line you've already got.
Laser-cut galvanised steel, fitted to mesh, palisade, Colorbond or timber, turns a standard commercial fencing setup into commercial security fencing without a full rebuild. A lower-cost, lower-liability step up from barbed or razor wire that looks like it means business.
Commercial-grade profiles with the 2.4m Bull, croc-top and high-profile options, plus the backing plate accessory for mesh, palisade and Colorbond mounting.
Perimeter Security That Stops the Climb
Most perimeter breaches don't happen through a locked gate, but over the fence, at the point furthest from the office, the cameras or the street. An anti-climb fence topper hardens that point, removing the flat-top edge that makes climbing possible.
It is not a replacement for cameras, alarms or patrols; it's the layer that makes all of them work harder by slowing a climb down long enough for the rest of your perimeter security to do its job.
Construction Site Security
Tools, copper, plant and materials are the most commonly targeted items on a build, and most of it goes over the hoarding or boundary fence overnight. Our construction site security toppers fit straight onto the existing perimeter or hoarding line, so there's no separate structure to build and no delay with installation.
Because security fences are fitted to what's already there, toppers work just as well on a short-term hoarding as a permanent boundary fence once the build is done, so the same investment covers both stages.
Turn an Existing Fence into a High-Security Fence
You don't need to replace mesh, palisade or Colorbond fencing to meet high-security fence standards; you need to fix the weak point, which is almost always the top line.
Fitting a security fence along an existing perimeter raises it to a spec that matches higher-risk sites, without the cost or disruption of a full replacement.

Looking after a home boundary? Our residential fence security and wider fence toppers and wall spikes range delivers. If your issue is pests rather than people, our bird and pigeon spikes or cat and possum spikes offer more targeted support.
Galvanised Steel, Built for Spec
Our anti-climb fence spikes, including the commercial profiles, are laser-cut from galvanised steel, built to hold their edge and resist rust through years of outdoor exposure.
Profiles, thicknesses and lengths are customisable, so a spec can be matched to the risk level of the site rather than a one-size-fits-all product.

Compliance & Duty of Care
Anti-climb fences are generally an accepted deterrent on a boundary a business owns or occupies, provided they're mounted out of casual reach and accompanied by warning signage where the public may pass close to the fence. Requirements vary by state, so it's part of a proper duty-of-care review alongside your usual WHS obligations. For the full breakdown, see our fence spikes legality guide.

What are the compliance and duty-of-care requirements?
Mounting height, signage and council rules vary by state. See our full legality guide for the complete answer.
