Barrier issue

Trees, Shrubs & Vines Near Pool Fences: What Passes and What Fails?

Trees, shrubs and vines near a pool fence don't automatically cause an inspection failure. What matters is whether they provide usable climbing points.

These illustrated examples show what can pass, what can fail, and how to fix common problems.

As a general rule, seek advice before planting within 900mm horizontally of a pool barrier.

What parts of a tree can support climbing?

Branch tips can appear flimsy, but a branch junction (where a branch joins the trunk or another branch) can be strong enough to create a climbing point for a young child. This is often called a fork.

FAIL

Accessible branch junctions

Thin outer branches can bend, but junctions closer to a trunk can create usable climbing points.

FIX: Remove the plant, or prune suitable trees to a single smooth vertical trunk at least 1200mm above ground level.

PASS

Lightweight, flexible plant

It looks similar, but the thin main stems bend down under weight instead of providing effective climbing support.

BE CAREFUL: Regrowth can create stronger climbing points. Reassess as the plant grows.

Vines wrapped around pool fences

Climbing vines wrapped around vertical pool fence bars, creating potential climbing points.
FAIL

Vines create usable climbing points

Wrapped stems can hold weight, even when individual vines are thinner than 10mm.

FIX: Remove vines from the fence and prevent regrowth.

Dense hedges: a critical difference

Exceptionally dense growth can prevent access to branches, but trimmed ends may expose them.

POTENTIAL PASS

Exceptionally dense hedge

The branch structure cannot be reached, including at the ends.

WATCH THE HEIGHT: A hedge below the height of the pool barrier will typically provide a climbing point at its top.

FAIL

Trimmed hedge end

Exposed branches and junctions provide accessible climbing points.

FIX: Remove access to the exposed branch structure or remove the hedge.

Illustrative examples. Compliance depends on the plant and surrounding barrier.

What about thorny plants?

POTENTIAL PASS

Natural thorn deterrent

Some lemon, lime and other naturally thorny plants may deter climbing. The individual plant still needs assessment.

CHECK: Natural thorns must genuinely deter access to climbing points.

Large trees and the upper non-climbable zone

FAIL

Branches reaching into the upper zone

A tree can be outside the lower 900mm zone but still create climbing points where its branches extend into the upper NCZ.

FIX: Prune branches clear of the upper NCZ, or remove the tree if needed.

Illustrative example, not a recorded inspection result.

So, how do you fix climbable vegetation?

  • Remove the tree, shrub or vines causing the problem.
  • Relocate the plant away from the barrier.
  • Prune suitable trees to a single smooth vertical trunk for at least 1200mm vertically from ground level.

Also check: Branches extending into the upper non-climbable zone.

THE KEY POINT

It's the climbing points a plant creates, not how harmless its branches look, that matters.

The law

Queensland pool safety requirements

Queensland's pool safety standard, QDC MP 3.4, requires the applicable 900mm non-climbable zone (NCZ) and additional clear area to maintain the barrier's minimum effective height of 1200mm. Vegetation can cause non-compliance where it creates accessible climbing points or reduces the effective barrier height.

EasyPoolCert assesses branches, trunks, forks, cut stumps, converging stems and vines that may provide a young child with climbing support. Projections exceeding 10mm are a particular concern, but thinner branches can also create climbing points at strong junctions. Foliage that can be pushed aside, openings greater than 100mm, and exposed branches at trimmed hedge ends are important accessibility considerations. Smooth vertical trunks without usable projections, and genuinely inaccessible vegetation, may be assessed as non-climbable.

Common questions

My tree passed its last pool inspection. Could it fail the next one?

Yes. As trees and shrubs grow, new branches and forks can create accessible climbing points. Vegetation that was compliant previously may become non-compliant, so regular trimming and maintenance are important.
