1.2m minimum height. No climbable objects within 900mm outside the fence. Self-closing, self-latching gate with the latch 1.5m up. Vertical bars no more than 100mm apart. Gap under the fence no more than 100mm. Compliance certificate required for sale or lease, valid 3 years.
Pool fencing in NSW runs off two documents: the Swimming Pools Act 1992 and Australian Standard AS 1926.1. Northern Beaches Council enforces both. The rules are specific and unforgiving, and most fail results come down to the same handful of issues. This is what to check before booking an inspection.
The non-negotiable specs
- Height: 1.2m minimum, measured from the outside finished ground level.
- Gap under fence: Maximum 100mm.
- Vertical bar spacing: Maximum 100mm.
- Horizontal rail spacing: If two horizontal rails on the outside, minimum 900mm apart (the “non-climbable” rule).
- 900mm climbable zone: Outside the fence, nothing climbable within 900mm radius of the fence.
- 300mm zone inside: Above any horizontal rail accessible from inside the pool area, no climbable objects within 300mm.
- Gate: Self-closing from any open position, self-latching, opens outward, latch at least 1.5m above ground or shielded.
- Boundary fences used as pool fences: Must be 1.8m high if they form part of the pool barrier.
The 900mm climbable zone — the rule that catches most owners
This is what fails the most inspections. The standard treats anything climbable outside the fence as a step that lets a child up and over. “Climbable” is interpreted broadly:
- Garden pots over 150mm tall
- BBQs, outdoor furniture, esky boxes
- Retaining walls, raised garden beds
- Tree branches that could support a child’s weight
- Pool pumps, filter housings, equipment cabinets
- Air conditioning condenser units
- Children’s toys, trikes, scooters
If the inspector finds anything climbable in that 900mm zone, you fail. Walking the perimeter and clearing it before the inspector arrives saves the rebooking fee.
Gates — the second-biggest fail category
The gate has to do four things every single time, with no exceptions:
- Self-close from any position. Open it 50mm, let go — it must close. Open it fully, let go — it must close. Self-closing hinges weaken with age; replace them every 5–7 years.
- Self-latch. The latch must engage automatically when the gate closes.
- Open outward. Away from the pool, never inward.
- Latch height. 1.5m minimum from outside ground level, or shielded with a 450mm radius cover so a child can’t reach over.
You also can’t prop the gate open. Wedging it open while you mow the lawn is technically a breach.
Where Northern Beaches Council adds local nuance
Northern Beaches Council follows AS 1926.1 strictly — they don’t add stricter rules, but they enforce two things hard:
- Boundary fences used as pool fences. If your neighbour’s 1.8m timber fence forms part of the pool barrier, the council inspects it as part of the pool fence. Holes, knot voids and missing palings on the neighbour’s side are your problem.
- Foreshore lots. Pools on Pittwater or beach-front blocks often have a glass pool fence to preserve view. Glass panels still must meet the climbable and gap rules — some heritage glass panel installations from the 90s no longer comply.
How to register and certify
Every pool in NSW must be on the NSW Swimming Pool Register (free, online). You then need a Certificate of Compliance, issued by Northern Beaches Council or an accredited private certifier. Compliance certificate is valid 3 years.
You need a current certificate at the point of:
- Selling the property (must be in the contract for sale)
- Leasing the property (must be provided to tenants)
- Council inspection request
Inspection cost: $150–$350 for a council inspection, $350–$650 for a private certifier (includes re-inspection if you fail the first). Most inspectors will give you a punch list of issues; fix them and rebook.
What a fence costs to bring up to code
Common scope of work to remediate a non-compliant pool fence:
- Replacing self-closing hinges and latch: $350–$650
- Removing pots / relocating BBQ from climbable zone: $0–$1,500
- Adding extra panel to boundary fence to reach 1.8m: $180–$400 per LM
- Replacing entire fence with compliant tubular or glass: $250–$650 per LM (tubular), $550–$900 per LM (glass)
- Re-grading ground to fix >100mm gap: $400–$1,800
Most non-compliant fences can be remediated for $1,500–$4,000. Full replacement only kicks in when the existing fence is the wrong height or has fundamentally non-compliant geometry.
The bottom line
If you’ve got a pool, the inspection is going to happen at some point — usually when you sell. Getting it compliant now costs less than fixing it under contract pressure. Walk the perimeter, clear the 900mm zone, test the gate, measure the latch height. If anything fails, fix it before you book the inspector.

Frequently Asked Questions
What height does a pool fence have to be in NSW?
Under AS 1926.1, a pool fence must be at least 1.2m (1200mm) high, measured from the finished ground level on the outside.
What is the climbable zone for a pool fence?
A 900mm radius climbable zone applies on the outside of the fence — no climbable objects (pots, BBQs, retaining walls, branches, furniture) can sit within 900mm. Inside the pool area, a 300mm non-climbable zone applies above any horizontal rail.
Do pool gates need to be self-closing?
Yes. All pool gates must self-close from any starting position and self-latch. Latch must be at least 1.5m above the ground or shielded. Gates must open outwards, away from the pool.
How often does a pool fence need inspection in NSW?
Under the Swimming Pools Act 1992, every pool must be registered on the NSW Pool Register and have a current Certificate of Compliance. Certificates last 3 years and are required when selling or leasing.
What’s the most common reason a pool fence fails inspection?
Climbable objects within the 900mm zone outside the fence, gates that don’t self-close, gaps under the fence wider than 100mm, and latches lower than 1.5m. These four account for the majority of fails.
