Most owners I meet know they need “some sort of certificate.” Far fewer can tell me which law actually requires it, which edition of the Australian Standard their barrier gets measured against, or what happens the day they sail past the 4-year deadline. So here is the whole picture: the law behind it, the registration step, the eight physical checks, the Form 23 paperwork, and the one detail that trips up nearly everyone — or see our homeowner guide for the plain-English walkthrough. The standard that applies to you is fixed by when your pool was built, not when you bought the house.
The Three Layers of Law Behind Your Pool
Pool safety in Victoria isn’t one rule. It’s three instruments stacked on top of each other, and knowing which does what will save you a phone call to the wrong person.
Building Act 1993 (Vic)
This is the parent statute. It hands the Building and Plumbing Commission (formerly the VBA) its powers, frames building permits and occupancy certificates, and gives everything below it legal footing. Every obligation tied to a Form 23 or to a registered inspector ultimately runs back to this Act.
Building Regulations 2018 (Vic)
The rules you’ll actually be held to sit in Part 9A of the Building Regulations 2018 (Vic): registration, the 4-year cycle, Form 23, Form 24, and the pointer to the Australian Standard your barrier has to meet. When a conveyancer or an inspector quotes you “the regulation,” nine times out of ten this is the part they mean.
Australian Standard AS 1926.1
The numbers (fence height, gap widths, what the gate has to do, where the non-climbable zone falls) come from Australian Standard AS 1926.1. There have been several editions — AS 1926–1986, AS 1926.1–1993, AS 1926.1–2007, and AS 1926.1–2012 — and the one that applies to your pool hangs entirely on when the barrier went in. Your council determines which standard applies. That single fact is the most misread part of the whole regime, so it gets its own section below.
Who Must Register a Pool or Spa in Victoria?
The Building Regulations 2018 (Vic) say anyone owning a pool or spa deeper than 300 mm must register it on their local council’s register. That 300 mm depth is the whole test. It catches a permanent in-ground pool and a fixed above-ground pool alike. A blow-up, inflatable or portable pool you empty after each use usually sits under the line — but a bigger inflatable left filled past 300 mm needs both registration and a compliant barrier, the same as any other pool. But the moment a pool stays filled and clears 300 mm, it needs registering, in-ground or not.
Buy a place with a pool that’s already on the register and the registration comes with the property. Never registered, or honestly not sure? Ring your council. Greater Geelong, Moorabool and Wyndham each run their own register, so there’s no central database to check. It’s the council that covers your address.
Registration is just the front door. The 4-year inspection clock starts ticking the moment the pool is on the register.
What About Inflatable & Above-Ground Pools?
Inflatable and above-ground pools aren’t automatically off the hook. In Victoria, any pool or spa that can hold more than 300 mm (30 cm) of water has to have a compliant safety barrier and be registered with your local council. That sweeps in a lot of the bigger inflatable and portable pools people assume are exempt. A small wading pool below that depth generally falls outside the rules — but it’s the depth that decides it, not whether the pool is “proper” or blow-up. If you’re about to set one up and you’re not certain where it sits, it’s worth a quick word with us at contact us before you fill it, or book a pool safety inspection once it’s in and holding water.
Which Australian Standard Applies to Your Pool?
Hardly anyone asks me this, and it’s the one that matters most. Your barrier is judged against the standard that was in force the day it was built, not the one in the book today. Victoria does not make you drag an older pool up to the current edition. Whatever era your barrier was built in, that’s the era it’s held to. Your council determines which standard applies to your pool from its records — usually by construction date or the date of the last major barrier alteration.
| Standard | Standard assessed against | NCZ radius (outside) |
|---|---|---|
| AS 1926.1-1993 era | AS 1926.1-1993 | 1200 mm outside clear span |
| AS 1926.1-2007 era | AS 1926.1-2007 | 900 mm outside |
| AS 1926.1-2012 era (current) | AS 1926.1-2012 (current) | 900 mm outside (NCZ 1–4) |
Here’s what that means on the ground: two pools in the same Geelong street, one fence over from each other, can carry genuinely different non-climbable zone requirements because they were built in different eras. So before any inspection, and well before you spend a dollar on barrier work, pin down which edition applies to your pool by checking with your council. Spend money fixing it to the wrong standard and you’ve spent it twice.
The Eight Things a Barrier Has to Get Right
Every edition of AS 1926.1 breaks a barrier into eight checks. There’s no pass mark to scrape over and no averaging out a weak spot against a strong one. Miss one and the whole barrier fails. I’ve signed off barriers that aced seven and failed on a single 110 mm gap under a gate.
1. Barrier Height — 1200 mm Minimum
At least 1200 mm (1.2 m), measured straight up from finished ground level on the outside (non-pool) side, taken at the lowest point anywhere round the perimeter. The catch is the slope. On a block that falls away, the ground drops out from under the fence at a corner and the effective height quietly slips under 1200 mm, even when the panels themselves look plenty tall. Highton, Waurn Ponds and the steeper streets of Belmont hand me this failure over and over.
For the full treatment of how height is measured on sloped blocks, see our guide to pool fence height in Victoria.
2. Gap Under the Barrier — 100 mm Maximum
Nowhere round the perimeter can the gap between the bottom of the barrier and the ground top 100 mm. The fence is rarely the problem here. It’s the ground: settling, washing out after heavy rain, or scooped lower by a landscaper who didn’t think about the fence line. The barrier hasn’t changed; the dirt under it has, and that’s still a fail.
3. Vertical Rail Spacing — 100 mm Maximum
No more than 100 mm between any two vertical members (pickets, rails, bars), and it has to hold for the full height of the barrier, not just down low. The 100 mm rail spacing guide shows where this one bites in practice.
4. Non-Climbable Zone (NCZ)
If there’s one rule that catches people cold, it’s this one. The non-climbable zone is also the failure I can almost never call from a photo. I have to stand there and sweep it with a measure.
Picture an arc thrown from the top of the fence, outward and down, on the outside: the side a child climbs from. Anything sitting inside that arc that a small set of hands and feet could use as a leg-up kills compliance. A low tree branch. The wheelie bin that lives beside the gate. A retaining wall. The pool pump left against the fence. Sometimes a horizontal rail on the fence itself, if it falls in the zone.
How wide that arc is depends on which standard governs your pool — your council determines that. Under AS 1926.1–2007 and AS 1926.1–2012, the radius is 900 mm. Under AS 1926.1–1993, it is 1200 mm — the bigger sweep, and that wider arc is exactly what snags older Geelong gardens, where twenty years of careful planting has quietly crept into the zone.
For the full NCZ explanation — including the four named zones under AS 1926.1-2012 — see our guide to the non-climbable zone.
Your pool’s build date decides which edition you’re measured against — and “grandfathered” is a myth. Before I measure a single dimension on a job, the first thing I work out is when the pool went in, because that’s the number that tells me which rulebook I’m holding you to:
- Built 1 Nov 1994 – 30 Apr 2010 → AS 1926.1–1993: the wider 1200 mm non-climbable zone.
- Built 1 May 2010 – 30 Apr 2013 → AS 1926.1–2007: a 900 mm zone, 1200 mm minimum height.
- Built from 1 May 2013 → AS 1926.1–2012 (current): the four named non-climbable zones.
You’ll still hear that older pools are “grandfathered” and exempt. They aren’t. Every pool gets re-inspected on Victoria’s four-year cycle against the standard for its era, full stop. If you don’t know your install date, that’s where we start.
A tall fence catches people out here. On a recent Geelong inspection the boundary fence stood about 2.2 m — well over the minimum, and the owner assumed height alone settled it. It doesn’t. On a current-standard pool the non-climbable zone on a boundary fence is measured from the top of the barrier, on the pool side, so even a 2.2 m fence has to be kept clear of anything climbable up near the top. This one had a few heavy tree limbs reaching into that zone; they came off, and then it passed. Height buys you nothing if there’s a ladder of branches at the top.
5. Gate: Self-Close and Self-Latch
Let the gate go from any open position, wide or barely cracked, and it has to swing shut and latch on its own, no hand on it, no push. It also has to open away from the pool, never inward. The sneaky failure is the gate that snaps shut and latches from 90° but doesn’t quite make it from 15°. Most owners only ever test theirs from wide open. The test takes 30 seconds; our 30-second gate test shows you how to do it from the angle that actually fails.
Two things on the same gate can trip it up, and I saw both on a Torquay job recently. First, the gate has to swing away from the pool, not towards it — this one was fitted to open inward, so it had to be re-hung to open out. Second, the 1500 mm latch height is measured from the finished ground at the latch, not from wherever’s convenient: the outside of this gate opened onto a step, so once you measured from that lower step level the release sat under 1500 mm and had to be raised. From a distance the gate looked fine — it’s the kind of thing that only shows up when someone actually measures it.
6. Gate Latch Height
Mount the latch release at or above 1500 mm from the ground and you’re done; no extra shielding needed. You can go lower, but then AS 1926.1–2007/2012 wants specific shielding around it. What I see most often is a latch that started at the right height and crept down over the years as the posts settled or someone re-hung the gate hardware a touch lower. It was compliant once. It isn’t now.
7. Windows, Doors, and Other Access Points
Any door or window in a house wall that opens straight onto the pool (a back door, a laundry window, a sliding door) has to clear the barrier rules itself. If it gives access to the pool without first passing through the fence line, it’s part of the barrier and gets assessed as part of the barrier.
8. Hardware Integrity
Hinges, springs, latch mechanisms: all of it has to actually work, not just look intact. Coastal Geelong and the Bellarine are where this falls apart, and it’s salt. Salt air bleeds the tension out of a gate spring and seizes a latch far quicker than anything inland sees. A few streets back from the water at Ocean Grove or Barwon Heads, hardware that was perfect on install day can be done inside a couple of years. Our coastal pool barrier guide covers what the salt does and how to catch it before inspection day does.
For a pre-inspection walkthrough across all eight categories, the Victorian pool safety checklist covers what to look for before the inspector arrives.
The Form 23 Certificate, and How the Process Actually Runs
A Form 23 Certificate of Pool and Spa Barrier Compliance is the document where a VBA-registered inspector records that your barrier met the applicable standard on the day they looked at it. Read that last bit carefully. It certifies a moment in time, not a four-year warranty. A gate spring that gives out next winter doesn’t care what the certificate says.
Who can issue a Form 23?
Only an inspector holding current VBA registration with an IN-PS (Inspector — Pool Safety) licence number. A Form 23 from anyone without that registration is worth nothing: council won’t take it, it won’t cover your Section 32 disclosure, and it won’t tick the 4-year box. You don’t have to take my word for who’s registered. The VBA Practitioner Search at vba.vic.gov.au is free. Type in the IN-PS number, and make sure the status comes back “Current.” Mine is IN-PS 100055; punch it in and check it before I ever turn up. Our guide to VBA pool safety inspector registration walks through what the registration actually covers.
What is a Form 24?
A Form 24 is the formal non-compliance notice that goes to council, and it’s the form owners worry about far more than they need to. It does not fire off every time a barrier fails. The normal path when something fails: I write up exactly what’s wrong, you fix it, I come back and re-check — see if your barrier doesn’t pass for how that re-check works. A Form 24, which comes with a council fine attached, only gets raised when a barrier is an immediate danger to life. In the overwhelming majority of failed inspections, it never comes up.
The 4-year renewal cycle
Every four years, a VBA-registered inspector has to look at your barrier. Pass, and they issue a Form 23, which you then have to lodge with your council inside 30 days. Greater Geelong, Moorabool Shire and Wyndham City each keep their own register, so the certificate goes to whichever council your address sits in, not to some state-wide office.
And the clock runs off the date of your last compliant Form 23, not off the calendar. Form 23 dated September 2022? Your next one is due by September 2026 — the day you bought the house or the year you registered the pool doesn’t reset it. Wondering whether anything actually changed this year? See what’s new for Victorian pool owners in 2026 (short version: keep your certificate current).
Who issues the initial Form 23 for a new pool?
Here’s a wrinkle that catches new builds. The very first Form 23, the one at the end of construction, comes from your building surveyor as part of signing off the build, not from a pool safety inspector. After that first certificate, every 4-year renewal and every pre-sale check is our patch. So if you’re a week into a brand-new pool, don’t call me yet; the surveyor closing out your build is who you want. After that, we’ve got you.
Selling a Property With a Pool
A pool adds exactly one step to selling a property in Victoria, but the timing of that step is where vendors trip. A current Form 23 has to sit in your disclosure to the buyer. My advice, learned from the ones who left it late: book the inspection before the photographer shows up, not after the contract’s signed. Find a barrier problem early and it’s a quiet repair. Find it mid-contract and it’s suddenly a settlement risk with a clock running.
Our guide to selling a house with a pool in Victoria lays out the full timeline: when to book, what happens if the barrier needs work, and where the Section 32 fits.
What a Pool Inspection Costs in Victoria
We charge a flat $250 (inc. GST) for a pool or spa barrier inspection across Greater Geelong, the Bellarine, Moorabool Shire and the Wyndham corridor. One price. It covers the inspection, the Form 23 if you pass, the written report listing what’s wrong if you don’t, and the re-inspection after you’ve fixed it. No travel surcharge tacked on for a Bellarine address, no separate line item for the certificate. That’s the same flat rate whether we’re out at pools in Greater Geelong or booking Surf Coast Shire pools.
Our Geelong pool inspections guide breaks down exactly what the $250 includes, and the rare things that genuinely sit outside it.
Common Questions About Victorian Pool Regulations
Do I need to register my pool or spa in Victoria?
Yes. The Building Regulations 2018 (Vic) require every pool or spa over 300 mm deep to be on the local council’s register. If you can’t say for sure whether yours is registered, ring the council and ask. Councils run audit programmes that keep finding unregistered pools, and an unregistered pool can’t be a compliant one. Registration is the step everything else hangs off.
What is a Form 23 and when do I need one?
It’s the Certificate of Pool and Spa Barrier Compliance: a VBA-registered inspector’s record that your barrier passed on the day they checked it. You’ll need one for the 4-year cycle and again when you sell. It has to reach council within 30 days of being issued. One thing to keep straight: a Form 23 certifies that one day, not the four years after it. A barrier can drift out of compliance the week after it passes.
How often does my pool barrier need to be inspected in Victoria?
Once every four years. A VBA-registered inspector checks it, issues a Form 23 if it passes, and you lodge that with council inside 30 days. Your next inspection is then due four years on from that certificate’s date, not on any fixed calendar year. See our FAQ for more on how the re-inspection cycle runs.
Which Australian Standard applies to my pool barrier?
Whichever edition was current when the barrier was built — AS 1926–1986, AS 1926.1–1993, AS 1926.1–2007, or AS 1926.1–2012. Your council determines which standard applies to your pool from its records. You are not required to upgrade an older barrier to the current edition. It’s judged by the rules of its own era.
What is the minimum height for a pool fence in Victoria?
1200 mm (1.2 m), measured straight up from finished ground level on the outside, at the lowest point round the perimeter. On a sloping Geelong block the real measured height can land well under that even when the panels look tall. It’s exactly why so many fences that “look fine” fail on height.
What happens if my pool barrier fails inspection?
You get a written report spelling out precisely what needs fixing. You sort it (with a licensed trade where the job calls for one), then I come back and re-check. With us that re-inspection sits inside the same $250, no second call-out fee. A Form 24, the council notice that carries a fine, only comes into it where the barrier is an immediate danger to life. A run-of-the-mill fail doesn’t trigger one.
