Swan says yes, in writing, for now
The City of Swan takes a middle position that neither of its neighbours takes. Synthetic turf sits under "Other Permissible Verge Treatments", introduced by a sentence that is worth reading in full: "The use of hardstand treatments other than for paths and crossovers is not normally encouraged within the City for safety, drainage, environmental and aesthetic reasons. The following treatments are allowed but require written permission from the City." You lodge an Application to Alter Verge Form with a plan, and if the City approves the plan, that is your authority.
There is a genuine watch item attached, and Ballajura homeowners should know about it before they commit money. At the City of Swan annual electors meeting on 2 February 2026, residents carried motions asking the City to consider removing synthetic lawn from the approved verge list and to investigate prohibiting synthetic turf on private property, with an exception for sporting grounds. Echo Newspaper reported on 12 February 2026 that the council was expected to consider the motions later in the year. A motion at an electors' meeting is a request to Council rather than a decision, and as at August 2026 the published Verge Guidelines still list synthetic turf as permitted with written approval. We would still ring the City first. Every other council in our coverage answers this question differently again, which we have set out in what each Perth council permits on a verge, quoted from the documents.
The obligations that come with a Swan approval are the ones people forget to budget for: maintain it in a safe and sound condition, reinstate it at your own cost if a utility digs it up, and leave at least one opening a metre square per frontage for a tree or garden bed. The same rules and the same watch item apply four kilometres away, so if you are comparing notes over the fence, see how the Swan approval works for a Beechboro verge.
Sand that holds water
Perth sand has a reputation for draining so well that drainage stops being a design question. On the Bassendean system that reputation is only half earned, and Ballajura is a good illustration. The Jandakot low dunes drain the way you expect. The Joel depressions, nearly a third of the suburb, do not: they are mapped as poorly drained, and the reason is what sits underneath rather than what sits on top. Across the Bassendean phases the dataset repeatedly records clay or a "weak iron-organic hardpan" at depth, typically somewhere between one and two metres. Water moves fast through the sand and then stops.
For a turf base, that turns into a practical instruction rather than an alarm. Ask what the ground does after rain, not just what it looks like dry. On the higher dune ground the base is straightforward and the sand does most of the work for you. On low ground, falls and where the water leaves the lawn area are worth deciding deliberately. Nothing in any Australian Standard or WA government document sets base depth or drainage for artificial turf by soil type, so this is a conversation with your installer rather than a compliance exercise.
The repellence figures are the other half of the local picture, and they are the reason a lot of Ballajura lawns look patchy no matter how carefully the roster is followed. Water Corporation puts the general case plainly: "Sandy soils are known to be water repellent (hydrophobic), making it a challenge to maintain a healthy garden in WA." Here, 42.2% of the suburb maps into the highest repellence class the dataset publishes.
What a Ballajura job usually involves
Most enquiries from this part of the north east are established yards rather than handovers, which means the work starts with removal rather than construction: lifting the existing lawn, carting the spoil, and capping the reticulation that used to feed it. Retic capping deserves its own line on the quote. Many Ballajura systems run off a garden bore, and a bore setup is plumbed differently to a scheme one, so mention it when you enquire.
After that it is the ordinary sequence: excavate, lay and compact the base in passes, screed it level, lay the turf with a consistent grain, join, secure the edges and brush in the infill. The detail that separates a lawn that still looks flat in five years from one that does not is entirely in the compaction and screeding, which is the part you cannot inspect once the turf is down. If you want the whole city view first, synthetic grass in Perth generally covers tiers, ranges and the water rules in one place.
Ballajura questions, including the one about the verge
Can I lay synthetic turf on my Ballajura verge?
Yes, with written permission first. The City of Swan's Verge Guidelines put synthetic turf under the heading "Other Permissible Verge Treatments", alongside paving and compact aggregate: "The following treatments are allowed but require written permission from the City". You submit an Application to Alter Verge Form with a detailed plan. Worth being precise here, because it is often reported wrongly: synthetic turf is not on Swan's banned list. That list covers asphalt, bitumen, concrete, structures and loose aggregate.
Is the City of Swan about to change its mind on this?
Possibly, and you should check before you order material. At the City of Swan annual electors meeting on 2 February 2026, two motions were carried: one asking the City to consider removing synthetic lawn from its approved verge treatments list, and one asking it to investigate prohibiting synthetic turf on all private property with an exception for sporting grounds. Echo Newspaper reported on 12 February 2026 that "The council is expected to consider the motions at an upcoming ordinary council meeting later this year." An electors' meeting motion is a request to Council, not a rule change, and as at August 2026 the published Verge Guidelines are unchanged.
What conditions come with a Swan verge approval?
Three that affect the build. You must install to the plan the City approved and maintain it "in a safe and sound condition". You must reinstate it at your own cost if a utility has to dig it up. And the design has to leave "at least one opening of a minimum of one metre by one metre in the hardstand treatment for the placement of a tree or garden bed per property frontage", with two or three openings on the side verge of a corner lot. Levels must also be set to direct water into the tree wells or garden beds where possible. Where there is no path, a 1.2 metre clear zone is required along the verge.
Is Ballajura built on sand?
Almost entirely, about 94% of it Bassendean System, but the sand is not uniformly dry. The Jandakot phase at 41.9% is "Jandakot low dunes", grey sand over pale yellow sands. The second largest unit, the Joel phase at 31.5%, is described simply as "Poorly drained depressions. Humus podzols." A further 2.6% maps as lakes and swamps and 2.2% as drainage lines. Deep sand and poorly drained are not contradictions on the Bassendean system, because a clay layer or an iron-organic hardpan sits underneath at depth and water stops when it reaches it.
Does that mean my lawn area could hold water?
It means it is worth checking rather than assuming, particularly on the low-lying parts of the suburb. Free-draining at the surface is not the same as free-draining all the way down. The useful question for an installer is not "does this sand drain" but "where does the water go once it is through the sand", and the answer is a site observation, ideally after rain. All of the percentages above describe the whole suburb polygon, parks and drainage reserves included, not any particular block.
Is water repellent sand a problem here?
It maps as one of the higher risk areas we cover. On the WA Government's Water Repellence Risk layer, 42.2% of Ballajura carries the class ">70% of map unit has a high water repellence risk" and another 11.4% carries "50-70% of map unit has a high water repellence risk", with 31.6% in the "10-30%" class and 8.2% unmapped. Those labels are percentages of a map unit, not odds for your house. For a natural lawn it means wetting agents and patchy dry spots are a normal part of life here. For synthetic turf it is one of the reasons people stop fighting it.
