Pool Fencing Regulations In WA: What You Need To Know

Drowning remains a leading cause of preventable death for children under the age of five in Australia. That single fact is why pool fencing regulations in Western Australia are among the strictest in the country, and why getting your pool fence wrong is not just a compliance issue but a safety one. We understand the regulations can feel overwhelming, especially when you are already deep in a pool build or renovation. This comprehensive guide covers the relevant requirements for every type of pool, what the Building Code of Australia demands, and what happens if your barrier falls short.

Which Pools Need A Safety Barrier In WA

The short answer: almost all of them. Under WA legislation, all private swimming pools and domestic swimming pools capable of holding water deeper than 300mm must have a compliant safety barrier. This includes in ground swimming pools, above ground pool installations, outdoor hot tubs, spa baths, spa pools, and even inflatable and portable pools that remain assembled for more than 30 consecutive days.

The rules apply equally to swimming and spa pools, bathing or wading pools, and indoor swimming pools where unsupervised access by young children is possible. If a child could reach the water without an adult unlocking a gate or removing a barrier, the pool area needs a compliant barrier installed to the current standard. No concession exists for the type, size, or depth of the pool. A backyard spa holding 500mm of water carries the same obligation as a full-sized swimming pool or spa.

Pools installed before the current regulations took effect are not exempt. Property owners with older pools and spas must upgrade their pool barriers to meet the current Building Code requirements or face substantial fines from their local government. This also matters if you are selling. A non-compliant pool barrier can stall a property settlement or void your home insurance entirely.

What The Building Code Requires

The BCA adopts Australian Standard AS1926.1 as the benchmark for pool barriers in Western Australia. Here is what that means in practice for your pool fence.

The barrier must be at least 1,200mm high, measured from the finished ground surface on the outside. No gaps in the fence, gate, or barrier can exceed 100mm at any point. The pool fence must be constructed from durable materials that cannot be easily damaged or removed. Fibre cement, aluminium, steel, frameless glass, and semi-frameless glass all meet the standard when installed correctly.

Gates must be self closing from any open position and self latching with the latch at least 1,500mm above the ground surface. Gates must open outward, away from the pool area. The clear distance between the bottom of the gate and the ground must not exceed 100mm.

Climbable objects are one of the biggest compliance failures we see. No horizontal surfaces, rails, or objects that could serve as a foothold can sit within 900mm of the barrier on the outside. That includes garden beds, pot plants, retaining walls, stored furniture, and air conditioning units. If a child could use it to climb over, it fails inspection. We have seen pool barriers that looked perfect on installation day fail six months later because someone moved a planter box against the fence. It is frustrating for the owner, but a three-year-old does not care whether the foothold was intentional.

Building Approval And Inspections

You need a building permit from your local government or permit authority before you install pool fencing or modify an existing barrier. The application requires plans showing the pool area, the proposed barrier location, gate positions, and any other factors that affect compliance like retaining walls or house walls forming part of the barrier.

After installation, your local government will conduct an inspection to confirm the barrier meets the strict regulations under AS1926.1. Many councils also run periodic inspections on existing pools, sometimes every four years, to check that the pool barriers are still operating effectively and that no modifications have compromised the safety barrier. Building approval for pool fencing in Western Australia is not optional. Without it, your installation has no legal standing regardless of how well it was built.

We handle the building approval process as part of every FencrGatr pool fencing project. That means we submit the application, coordinate with the permit authority, and make sure the barrier passes inspection first time. The relief on a homeowner’s face when the inspector signs off without a single correction is one of the best parts of what we do.

What Happens If Your Pool Fence Is Not Compliant

This is not an area where councils look the other way, and it is not an area where ignorance works as a defence. Property owners who fail to maintain a compliant barrier around their swimming pool or spa can face substantial fines of up to $5,000 per offence under WA law. Repeat non-compliance can lead to hefty fines and prosecution.

Beyond the financial penalty, the real cost of a non-compliant pool fence is the risk to life. Toddler drownings in domestic swimming pools are preventable, and every one of them is a tragedy that a properly installed and maintained safety barrier could have avoided. The safety regulations exist to prevent children from gaining unsupervised access to the pool area. They exist to restrict access by young children who cannot yet understand the danger. That purpose should sit at the front of every decision you make about your pool fence.

If you are unsure whether your existing barrier is compliant, we offer free pool safety inspections across Perth. We check barrier height, gate operation, gap measurements, climbable objects, and every detail against the current Australian Standards. If something needs fixing, we quote the work on the spot. Most homeowners tell us they sleep better once they know for certain their barrier is right.

Pool Fencing Regulation Questions

Here are the questions property owners ask us most about pool safety and compliance in WA.

Do Inflatable And Portable Pools Need A Fence?

Yes. Inflatable and portable pools that hold water deeper than 300mm and remain assembled for more than 30 days require a compliant safety barrier under WA law. Many homeowners assume small pools are exempt, but no concession exists for size. If young children could reach the water, the pool needs a fence.

Can My House Wall Form Part Of The Pool Barrier?

A house wall can form part of the protective barrier around the pool area, but any doors or windows in that wall that open to the spa area or pool must be fitted with self closing, self latching hardware that prevents children from accessing the pool. This includes sliding doors, which need compliant locks at 1,500mm height.

How Often Are Pool Barriers Inspected?

Inspection frequency varies by local government. Some Perth councils conduct periodic inspections every four years, while others inspect on complaint or during property sales. Regardless of when the council checks, it is the property owner’s responsibility to ensure the barrier is operating effectively at all times. We recommend a self-check at least once a year.

What Materials Can Be Used For Pool Fencing?

Pool barriers can be constructed from any durable materials that meet AS1926.1. The most common options are frameless glass, semi-frameless glass, aluminium, steel, and fibre cement panels. Each has different cost and style profiles. We install all types and help you choose the right option based on your pool area, budget, and the look you want to achieve for your property.
