Trampoline and Play Equipment Safety on Australian Residential Builds: AS 4989 and AS 4685

What it is

Two Australian Standards cover trampolines and play equipment on Australian residential sites. AS 4989 is the voluntary standard for trampolines used in the home. AS 4685 is the multi-part standard for playground equipment and surfacing. Both standards reference international counterparts (EN 71-14 for trampolines, EN 1176 for play equipment) and align Australian practice with global testing protocols.

Neither AS 4989 nor AS 4685 is mandatory under the National Construction Code for residential use. They are best-practice references that retailers, manufacturers, insurers and local councils use to assess whether equipment is fit for purpose. Where a builder is installing fixed play equipment as part of a residential build (a cubby house, a play tower, a fixed slide) the standards become the evidence base for safe installation.

The standards matter because childhood injury claims from trampolines and play equipment are common and the litigation pathway is well-trodden. A builder who installs equipment without consideration of clearance, surfacing and anchoring is increasing exposure.

Why it matters for residential builders

Builders installing fixed outdoor play equipment as part of a contract are providing the design and installation. That carries an obligation under the Australian Consumer Law (acceptable quality) and under each state's residential building Act (work performed with due care and skill). A child injured because equipment was installed too close to a fence, anchored to an unsuitable surface or supplied without adequate fall protection is a foreseeable risk.

The two most common injury patterns are falls from height onto hard surfaces and head impacts on adjacent structures within the fall zone. Both are covered by the standards. Both have been raised as factors in coronial findings and civil claims.

For builders supplying landscaping or play areas as part of a new home contract, getting the layout right at design saves expensive rework. A play tower installed too close to a fence cannot be retrofitted with a clearance zone without moving the equipment.

AS 4989: Trampolines for domestic use

AS 4989:2015 (revised in 2023) is the current Australian Standard for domestic trampolines. It covers safety aspects of trampolines designed for use in the home. The standard is voluntary but the Australian Competition and Consumer Commission references it as best practice and most major Australian retailers stock only AS 4989-compliant trampolines.

Core requirements include the following.

Frame and joint construction

The frame must withstand the forces generated by the maximum rated user weight without permanent deformation. Joints must not pinch or trap fingers. Padding must cover all parts of the frame, springs and edges that a user could contact.

Safety enclosure

AS 4989 requires (or strongly recommends, depending on edition) a safety enclosure to prevent falls from the trampoline. The enclosure must be at least 1.6 metres above the jump mat for adult-sized trampolines.

Maximum user weight and warnings

Every trampoline must carry a clear maximum user weight rating. The 2015 standard reduced the standard rating from 150 kilograms to 130 kilograms, which means a trampoline rated under the older standard does not automatically meet the newer one. Trampolines must carry warnings against simultaneous multi-user use, somersaulting and use without supervision.

Site requirements

The trampoline must sit on a level, well-drained surface with no objects within a 2 metre radius around the trampoline and no overhead obstructions within 7 metres vertically. The fall zone must be clear of trees, fences, furniture and other structures.

A common builder mistake is installing a trampoline pad too close to a boundary fence on a small block. The standard fall clearance cannot be met and the install is non-compliant from day one.

AS 4685: Playground equipment and surfacing

AS 4685 is a multi-part standard covering playground equipment and surfacing. It applies to play spaces that range from large public playgrounds to small private installations. The current parts include the following.

Part 0: Development, installation, inspection, maintenance and operation

Part 0 sets out the management framework: how equipment is installed, inspected and maintained over its life. It includes inspection schedules and the records expected for ongoing safety.

Part 1: General safety requirements and test methods

Part 1 covers the engineering and safety requirements that apply to all play equipment: entrapment gaps, finger and head probes, impact testing, structural integrity and warning labels.

Parts 2 through 11

Each subsequent part covers a specific equipment type. Part 2 (swings), Part 3 (slides), Part 4 (runways), Part 5 (carousels), Part 6 (rocking equipment), Part 11 (spatial networks).

Surfacing

AS 4685.6 covers impact attenuating surfacing. The standard sets out the required critical fall height performance of surfaces under and around play equipment. Sand, bark chips, rubber matting and synthetic surfaces are all permitted within their tested performance range. Hard surfaces (concrete, paving, compacted soil) under play equipment are non-compliant.

Fall zones and clearance

Both standards put fall zones at the centre of safety. The fall zone is the area around equipment where a child could fall and onto which impact attenuating surfacing must extend.

A simple rule for residential play equipment is a minimum 1.8 metre fall zone in every direction from any part of the equipment a child could fall from. For swings, the fall zone extends to twice the swing length in the direction of travel. The fall zone must be surfaced with material that meets the critical fall height for the equipment.

The fall zone cannot contain hard surfaces, fences, trees, sharp edges or other equipment. Two pieces of play equipment must be far enough apart that their fall zones do not overlap unless both pieces are designed for that combination.

Documentation and handover

For builders installing fixed equipment as part of a contract, the documentation pack should include the following.

Manufacturer evidence

Compliance statement, declaration of conformity to AS 4989 or AS 4685, age rating, maximum user weight and installation instructions.

Site plan

Marked-up plan showing the equipment location, fall zone boundaries and the surfacing extent. Photographs at completion are useful.

Maintenance schedule

A copy of the manufacturer's inspection and maintenance instructions handed to the homeowner. AS 4685.0 sets out routine visual checks, operational inspections (every one to three months) and annual main inspections.

Anchoring detail

Where equipment is anchored, the foundation design and any engineer involvement should be on file. Concrete footings should be set below ground level so they are not exposed in the fall zone.

Common defects

The defects that turn up most often on residential play equipment installs are predictable.

Fall zone shortfall

Equipment installed too close to fences, walls, pavers or other equipment. The fix is moving the equipment or installing protective surfacing.

Wrong surfacing

Bark chips that have been raked away or compacted to a depth below the manufacturer's spec. Hard ground exposed under a swing or slide. The fix is restoring the surfacing.

Exposed footings

Concrete footings sticking up above ground level inside the fall zone. The fix is burying the footings or fitting padded covers.

Old standards on new gear

A trampoline supplied or installed that meets an older edition of AS 4989 with a higher user weight rating than the current standard allows. The fix is replacement, not a workaround.

A builder who specifies layout, fall zone and surfacing at the design stage and documents the installation has done what the standards expect.
