Pool landscaping ideas, and the rule that undoes them

The non-climbable zone decides your planting plan

Start here, because every other decision on this page is downstream of it. Australian barrier rules require a continuous non-climbable zone: for a barrier less than 1800mm tall, a 900mm clear area measured as an arc on the outside of the fence, and a 300mm clear area on the inside. The barrier itself must be at least 1200mm above finished ground level.

The QBCC's published list of climbable objects reads like a description of a finished backyard: BBQs and outdoor furniture, trees, shrubs or overhanging branches, pot plants, garden features such as rockeries or raised garden beds, plus air-conditioning units, toys, stairs and window sills. Where two fences meet at a corner, the guidance goes further and calls for the corner to be treated for at least 900mm both inside and outside, because a corner gives a child two surfaces to brace against.

If your block genuinely cannot give you 900mm outside the fence — a common problem on narrow inner-suburban lots — there is a documented alternative: build the barrier to a minimum 1800mm in height and rely on the internal non-climbable zone. It is a real option, not a workaround, but it changes the look of the yard substantially and is worth pricing before you commit to a design.

Queensland's requirements sit in the Queensland Development Code MP3.4 rather than in AS 1926.1 directly; the 900mm zone is common to both. Check your own state's variation before you finalise a planting plan.

Ground level is a moving target

The single most under-appreciated fact about pool landscaping: the barrier's height is measured from finished ground level. Queensland's guidance says it plainly — ground levels and garden beds rise over time, reducing the pool barrier's height.

So a fence that was 1250mm at handover becomes a 1150mm fence, and non-compliant, after 100mm of new turf, mulch, decking or a garden bed is built up against it. Nobody did anything obviously wrong. The landscaper was not told the fence line was regulated, and the pool builder had already left.

Two practical consequences. First, if landscaping is a separate contract from the pool — which it usually is — the barrier requirement needs to be written into the landscaping scope, not assumed. Second, if you are landscaping around an existing pool, measure the fence height at several points before and after, because the failure is invisible until an inspector puts a tape on it.

Screening and privacy without building a ladder

Privacy is the most common reason people plant near a pool fence, and it is the most common way they break it. Hedging planted at 400mm tall sits well outside the 900mm zone on the day it goes in and is inside it three years later.

What works instead:

• Plant to mature width, not nursery width. Measure 900mm from the outside face of the fence, then add the plant's expected mature spread, then plant.
• Screen with the barrier rather than beside it. A solid or slatted panel that is the barrier, detailed with no footholds and no horizontal rails within the non-climbable zone, gives privacy without a second structure to keep clear.
• Put the planting on the pool side where the zone is 300mm, not 900mm — but check gaps between vertical members, which must generally not exceed 100mm, and remember the inside zone still exists.
• Keep overhanging branches in the maintenance schedule. Branches above the fence count, and they are the item most likely to have changed since the last inspection.

The same logic applies to everything else that migrates towards a fence line: the BBQ, the pool storage box, the trampoline, the stack of pavers left over from the build.

What the surfaces cost, and why the rates look contradictory

Published paving figures look irreconcilable until you notice what each one is measuring. A national cost guide puts paving and coping across a pool project at $8,000 to $45,000. Per-square-metre figures from Australian cost guides range from $40 to $65 for pavers supplied, $40 to $110 for porcelain and $25 to $150 for natural stone, with tiling labour at $50 to $85 per square metre for a standard patio and $85 to $150 per square metre for a pool surround. A builder guide meanwhile quotes paving “generally around $500 to $1,000 per square metre”.

Those are not the same measurement. The low figures are materials supplied. The high figures are a finished, laid, drained, compliant surface with the material included. Both can be honest and only one of them is what you will pay.

The premium on pool-surround labour over standard patio labour — roughly $85 to $150 against $50 to $85 per square metre — is the honest signal here. Pool surrounds carry slip resistance, falls and drainage requirements that a courtyard patio does not, and they interface with the coping and the barrier.

When you compare landscaping quotes, force them onto the same basis: same square metreage, same material, supply and install, drainage included, and state who is responsible for the finished level at the fence line.

Decking, levels and the things that become platforms

Decking around a pool does two things at once: it looks right, and it raises the ground. A Perth cost guide puts pool decking at $295 to $580 per square metre, and notes that poolside extras — compliant fencing, non-slip boards, coping and drainage — sit alongside that rate rather than inside it.

The compliance question with decking is not the deck itself but its edge. A raised deck, a bench seat, a planter box or a step built within 900mm of the outside face of the barrier is a platform, and a platform is exactly what the non-climbable zone exists to prevent. Retaining walls do the same thing where a sloping block is terraced near the pool.

Design the levels and the fence line together, in one drawing, before either is built. It is far cheaper than moving a fence.

Planting choices that do not end up in the filter

Compliance aside, the practical constraints around an Australian pool are leaf drop, root behaviour and salt. Fine leaf litter and blossom are worse than large leaves because they pass the skimmer basket and load the filter. Vigorous root systems near a shell or near paving are a long-term repair cost rather than a maintenance one. Plants immediately downwind of a saltwater pool cop splash-out from a chlorinator system.

None of that is regulated, so treat it as design judgement rather than rule-following, and ask a landscaper who has worked around pools specifically. What we would not do is publish a species list dressed up as fact — what tolerates a poolside position in Darwin has little to do with what tolerates one in Hobart.

The one thing worth being firm about: whatever goes in, check it against the 900mm arc at its mature size before it is planted, because moving an established hedge costs more than choosing a different one.
