Important Pool Fence Compliance Facts

May 5, 2020

Boundary Barrier

The most common miscon- ception with swimming pool barriers relates to fences that are shared with your neighbour. Under the current Australian standard, boundary barriers must be 1800mm high and the NCZ or clear area is measured on the inside of the barrier.

In addition, retaining walls, objects or level changes that would otherwise reduce the height of a barrier within a property must be located at least 500 mm from the barrier.

Examples of objects that may not be compliant include climbable barriers, trees, shrubs, pool filtration equipment and garden sheds. These objects often need to be moved or modified.


Statistics show that over 90% of swimming pools fail the first inspection for compliance. There is no substitute for supervision of children at all times when swimming.

NCZ Boundary Fence Compliance


Definitions Of Non Climbable Zones

NCZ1 is a 900mm vertical plane on the outside face of a barrier.

NCZ2 is a quadrant on the outside of a barrier created by a 900mm radius down from the top of NCZ1. NCZ3      is a quadrant on the outside of a barrier created by a 900mm radius up from the top of the barrier.

NCZ4 is required on all barriers with vertical openings 10mm to 100mm in width and is a 900mm high x 300mm wide deep rectangular space on the inside of the barrier.

NCZ5 applies to all 1800mm boundary barriers only and is the quadrant on the inside of the barrier created by a 900mm radius down from the top of the boundary barrier.
