Pool gate won't close or latch? NSW gate rules and how to test it

Published 22 October 2026

NSW pool gate rules

The NSW Government's guide for pool owners has a gate checklist. It says to check that the gate:

• "is never propped open and is always kept shut"
• "swings outwards (away from the pool area)"
• "shuts automatically from any open position, without having to forcibly close it"
• "automatically locks (self-latches) when it closes"

The law behind it is the Swimming Pools Act 1992: section 16 says gates giving access to the pool must be "kept securely closed at all times when they are not in actual use", and section 15 says the barrier must be kept in a good state of repair.

Pool gate latch height in NSW

The NSW Swimming Pool Register's self-assessment checklists, which councils still publish, give two options for the latch release:

• On the outside: "The release for the gate latch must be 1500mm above ground level"
• On the inside: the release is on the pool side of the gate behind a 450 mm shield, reached over the fence or through an access point 1200 mm above the ground, with the latch at least 150 mm below the top of the fence or shield

Councils describe the inside option in slightly different words, and the full detail sits in the Australian Standard for your pool's age. The checklists date from 2013, so treat them as a guide: the certifier decides whether your latch passes.

Measure from the ground the gate sits on, not from a step or a raised garden bed. Anything a child could stand on near the gate also matters, because it sits in the non-climbable zone.

How to test your pool gate

The register checklists say the gate "must be self closing and latch by itself from any position" and, once closed, "can't be pulled open". Our way of checking that at home:

1. Open the gate as far as it goes and let go without pushing it. It should swing shut and latch.
2. Open it halfway and let go. Then open it just off the latch, about a hand's width, and let go. It should latch both times.
3. Pull and push the closed gate. It shouldn't open without the latch being released.
4. Look underneath and around it. Nothing should catch the gate or hold it open, and the gap under it shouldn't be more than 10 cm.

Cessnock City Council's pool checklist adds a test for a child bouncing on the bottom rail: the latched gate shouldn't open. It also links each failure to a fix: if the gate doesn't swing back, replace the hinges; if it swings back but doesn't latch and stay closed, replace the latch; if it can be pulled open once latched, fix or replace the latch.

Test it after wet weather and after anyone works near the fence. A gate that worked last month can stop latching once a post moves or a hinge loses tension.

Why a pool gate won't close or latch

The hinges have lost tension

Spring hinges weaken with time, and a gate that swings slowly or stops short of the latch usually needs more tension. Hinge makers say both hinges must have equal tension.

The latch is out of line

If the gate swings shut but bounces off the latch, the latch or the gate has moved. A sagging gate, loose screws or a shifted post all change the line.

Something is in the way

Sand, leaves, a raised paver, a garden edge or a pool toy can stop the gate in its last few centimetres.

A glass gate has dropped

Glass gates hang on hinges clamped to the glass. A gate that has dropped or shifted no longer lines up with the latch, and Polaris, a glass hinge maker, says to tighten the hinge fixing screws every 6 months.

How to adjust pool gate hinges and latches

These steps come from the manufacturers' published instructions, not from NSW law. Hinges and latches vary, so check the brand and model on yours and follow its instructions.

TruClose self-closing hinges (D&D Technologies)

D&D's Australian FAQ says to increase tension on newer TruClose hinges, insert a flat-head screwdriver into the slotted adjustment dial, push down as far as it goes and turn it a quarter turn anticlockwise, then let the dial rise. That adds one setting. Do it equally on both hinges; D&D says one adjustment is usually enough. On older hinges, remove the small screw and black dust cap on top first. D&D's installation instructions for TruClose TCA and TCHD hinges (2011, hosted by a dealer) add: support a gate heavier than 15 kg while adjusting, never take the hinges apart, never remove the hinges from the gate until the spring tension is released, and use only powdered graphite, never petroleum-based lubricants.

Soft-close glass gate hinges (Polaris)

The Polaris care guide says to tighten the fixing screws every 6 months, but not the speed adjustment cap, and to fine-tune the cap to get the closing speed you want. It suggests checking gates near the coast every 2 to 4 weeks.

MagnaLatch latches (D&D Technologies)

For the MagnaLatch Top Pull with panic bar, D&D's May 2026 instructions say to loosen the striker pin's grub screw with a 2.5 mm Allen key, wind the pin out until it engages the latch, then tighten the grub screw. They give an ideal gate gap of 19 mm, within a range of 11 to 24 mm, for that model.

When a pool gate needs a contractor

Call a fencing or glass contractor if the gate still won't close after adjusting, a hinge or latch is broken or rusted, the gate opens the wrong way, the latch is too low, or a post or glass panel has moved. Re-hanging a gate, replacing hinges and moving a latch are routine fencing jobs.

Residential fencing work over $5,000 including GST needs a contractor licence. The pool fence repair cost guide has published gate repair prices. After a failed inspection, keep the certifier's list and book the re-inspection once the gate works. The failed pool inspection guide explains the timeline.
