Pool fence compliance on the Sunshine Coast comes down to one thing: meeting Queensland’s pool safety standard — and the rules are stricter (and more specific) than most people expect. This guide explains, in plain English, exactly what a compliant pool fence looks like under the current Queensland standard, so you can check your own barrier before it becomes a problem at sale, lease, or inspection time. It’s written by the team at Prime Pool Fencing & Balustrades, who have been installing compliant glass and aluminium pool fencing across the Sunshine Coast since 2017 as a licensed QBCC contractor (licence no. 15435283).
The Queensland pool safety standard at a glance
Pool safety in Queensland is governed by the Queensland Development Code Mandatory Part 3.4 (QDC MP3.4) and the Australian Standard AS1926.1. Together they set out the minimum requirements for any barrier around a regulated pool or spa. Here are the numbers that matter most:
- Minimum fence height: 1200mm, measured from the finished ground level to the top of the barrier, at every point — including on sloping or stepped ground.
- Maximum gap at the bottom: 100mm between the finished ground level and the bottom of the fence.
- Maximum gap between vertical bars: 100mm (for glass panels this simply means no gap wider than 100mm anywhere in the barrier).
- Non-climbable zone: a clear zone of 900mm on the outside of the fence and 300mm on the inside, kept free of anything a child could climb.
- Gates: must be self-closing and self-latching from any position, and must open away from the pool.
Fence height — the 1200mm rule
Every part of the barrier must be at least 1200mm high, measured vertically from the finished ground level to the top of the fence. The catch that trips people up is the words “at every point.” On a sloping block, a fence that measures 1200mm at one end can easily drop below the minimum further along, so the barrier has to step or rake to hold the height the whole way around. Garden beds, retaining walls, and built-up ground on the outside of the fence all reduce the effective height and can quietly push a previously-compliant fence out of compliance.
Gaps — under the fence and between the panels
The gap between the ground and the bottom of the fence can be no more than 100mm. This is one of the most common reasons an older fence fails: over time, soil erodes, mulch washes away, or paving settles, opening a gap wide enough for a small child to get under. No gap anywhere in the barrier — including between panels, between a panel and a post, or through a decorative feature — may exceed 100mm in any direction.
Horizontal rails are the other watch-point. If the barrier has horizontal rails or ledges that a child could use as footholds, the rails generally need to be at least 900mm apart (measured top of rail to top of rail). Where they’re closer than 900mm, the face of the fence has to be treated so it can’t be climbed — which is exactly why frameless and semi-frameless glass barriers are so popular here: a sheet of glass has no footholds at all.
The non-climbable zone (NCZ)
The non-climbable zone is the area around the fence that must be kept clear so a child can’t use nearby objects as a ladder over the barrier. For a standard 1200mm fence, you need to keep a clear arc of 900mm on the outside of the fence and 300mm on the inside, measured from the top of the barrier.
Anything a child could climb has to be kept out of that zone. In practice that means moving or removing outdoor furniture, BBQs, pot plants, trees and overhanging branches, garden beds and rockeries, steps and ledges, trampolines and toys, air-conditioning units, taps and pipes, and even window sills or deck edges that fall inside the measurement. If you genuinely can’t create the 900mm external zone, the alternative is to build the barrier to a minimum of 1800mm high and maintain the clear zone on the inside instead.
Gates — where most fences fail inspection
Pool gates are the single most common point of failure. A compliant gate must be self-closing from any open position and must self-latch every time — without anyone having to push or help it. It must open outward, away from the pool area, and it can never be propped, wedged, or tied open, even briefly. The latch should be positioned so it’s out of a young child’s reach (the standard places the release mechanism high on the gate, or shields it so it can’t be reached through or over the barrier). Because hinges and closers wear out, a gate that latched perfectly a year ago may not close fully today, so it’s worth testing yours regularly by letting it swing from fully open.
Windows and doors that open to the pool
Where a window opens into the pool enclosure, it must not be able to open more than 100mm, or it needs a fixed, compliant security screen. Doors giving direct access from the house into the pool area are generally not permitted as part of the barrier and usually need to be addressed with a compliant fence line instead. These are exactly the kinds of details a licensed inspector checks, and they’re easy to overlook when you’re only thinking about the fence itself.
Pool safety certificates (Form 23) in Queensland
A pool safety certificate — Form 23 — is the document that certifies your pool barrier complies with the standard. It’s issued only by a pool safety inspector licensed by the QBCC; a general builder, fencing contractor, or council officer cannot issue one. For a non-shared (standard residential) pool the certificate is valid for two years; for a shared pool, such as those at units, resorts, and holiday parks, it’s valid for one year.
You’re legally required to have a current certificate when you sell or lease a property with a pool. If an inspection turns up problems, the inspector issues a Form 26 nonconformity notice listing every item that doesn’t comply; once the work is done, you request a re-inspection and, if it passes, the Form 23 is issued. That’s where we come in — we don’t issue certificates, but we install and rectify fencing so it meets the standard the inspector is measuring against.
How Prime helps you get compliant

This guide is general information to help Sunshine Coast pool owners understand Queensland’s pool safety requirements. It is not a substitute for an inspection by a QBCC-licensed pool safety inspector. Only a licensed inspector can assess your pool against the full standard and issue a Form 23 pool safety certificate.
