When a boundary fence is part of the pool barrier
If your pool area runs up to the property boundary, the boundary fence itself becomes part of the pool barrier — and it's assessed as such at inspection. This is extremely common in Australian backyards and catches many owners off guard, because a fence that's perfectly fine as a boundary fence can fail as a pool barrier.
The higher standard that applies
- Height: boundary fences serving as pool barriers generally must be at least 1800mm on the inside (pool side) — not the usual 1200mm
- Non-climbable zone: a 900mm zone on the inside of the fence, measured down from the top — clear of anything climbable on your side
- No horizontal rails exposed on the pool side within the zone — rails must face the neighbour or be shielded with flat sheeting
- Gaps: the 100mm rule applies as usual, including under the fence
The logic: a child inside the yard can reach the boundary fence, so it must resist climbing from your side. The neighbour's side isn't your inspector's concern — but what leans against your side is.
Common problems and fixes
- 1500–1799mm paling fence: extend with lattice or height extensions rated for the purpose, or fence the pool separately inside the yard
- Exposed rails on the pool side: fix flat palings or sheeting over the rails to remove the footholds
- Neighbour's trees/structures: only your side's climbability is assessed, but overhanging branches within the zone still count — trim them
- Retaining wall raising your ground level: effective height is measured from your finished ground; a 400mm garden bed against an 1800mm fence leaves 1400mm — a fail as a boundary barrier
Boundary fence cost-sharing laws cover ordinary dividing fences — but the extra height and modifications needed for pool compliance are generally the pool owner's cost, not the neighbour's. Worth knowing before the conversation over the fence.
