Laying Artificial Grass in Sydney: The Process and What It Costs

What you are actually paying for when you lay a synthetic lawn

Start with the gap that confuses almost everyone comparing prices. Budget turf costs roughly $25 to $40 per square metre to buy as a product. Supplied and laid, the same tier is around $75 to $95. The extra is not margin on the grass. Published Australian industry figures put a typical job at roughly 40 per cent materials, 30 per cent base preparation and 30 per cent labour, which means well over half of what you pay buys excavation, road base, screenings, compaction plant, edging, infill and the hours of the people doing it.

Read that ratio once and several things become obvious. Moving up a quality tier changes only the materials component, so upgrading the turf costs less than the difference in product prices suggests, while the lifespan gap between tiers is large. Going the other way, buying premium fibre and letting someone economise on the base spends money on the layer that was never going to fail first. A quote that is dramatically cheaper than the others is almost always cheaper in the 30 per cent you cannot see once the lawn is down.

Price per square metre is also not flat across job sizes. Mobilising a crew, hiring plate compactors, ordering minimum quantities and removing spoil are largely fixed costs, so a compact courtyard carries a higher effective rate than a big open lawn. That is general reasoning about how trades price small jobs rather than a Sydney specific published figure, but it explains why a 20 square metre terrace yard can feel disproportionate.

Sandy east, heavier west, and why the digger has the final say

Sydney does not have one ground condition, it has several. Broadly, coastal and sandy country tends to be free draining, while much of the western and inland ground is heavier and clay based, which drains slowly and moves as its moisture content changes through the seasons. Those two situations ask different things of a base. Free draining ground is more forgiving of water, but loose sand still needs a properly compacted structural layer or the surface will settle unevenly under foot traffic. Heavier ground needs enough depth of free draining crushed rock, graded to a deliberate fall, to carry water sideways to an outlet rather than trusting the soil below to soak it away.

The honest caveat is that this is a tendency, not a map. Fill, old building rubble, previous landscaping, rock closer to the surface than expected and a neighbour's drainage all sit inside a single street, so what matters is what the installer finds when they dig, not the postcode on the envelope. That is also why a quote given over the phone from a photo is a guess. Anyone pricing your job properly should be able to tell you what they expect to hit, what they will do if the ground turns out worse than that, and how the price changes if it does. Our pages on synthetic lawn in Randwick and turf in Penrith and the western suburbs put the two ends of that spread in context.

Access is the second local variable, and on inner suburban blocks it can outweigh the ground. Everything going in (road base by the tonne, screenings, heavy awkward rolls of turf) and everything coming out (the excavated lawn, roots and topsoil) travels the same route. A rear lane or a driveway to the backyard makes it a machine job; a 900mm side gate, a set of steps and a wheelbarrow makes it a labour job, and the quote should say so rather than quietly absorb it. Somewhere to park the truck matters too on streets with no standing space. That is usually why a terrace quote reads so differently from a friend's quote out in a growth corridor estate.

The build, stage by stage, and where the corners get cut

An installer works through a fairly settled sequence, and knowing it lets you read a quote and a work site rather than take both on trust.

• Excavation. The existing lawn, roots and topsoil come out to about 75mm, or closer to 100mm where vehicles will drive on the surface. Irrigation heads in the area are capped off rather than left live under the turf.
• Weed membrane. A permeable geotextile is laid over the prepared ground by many installers, though Australian practice varies and some treat a well built compacted base as barrier enough. Ask which approach yours takes and why.
• Base build. Road base or crushed rock goes in as the structural layer, wetted and plate compacted, then a finer screenings or crusher dust layer is screeded over it, levelled to the falls and trimmed cleanly to kerbs and borders. A second screed pass is normal.
• Compaction, more than once. The base is compacted at least twice and made as hard as it practically can be. This is the stage that decides whether the lawn is still flat in five years, and it is completely invisible by handover day.
• Laying and grain. Rolls are set out to relax, then cut. The fibres lean one way, so the lawn reads a different shade from different angles and every piece must run the same direction or the joins map themselves out in contrasting tone.
• Joins. Edges are trimmed back a couple of stitch lines to remove the factory selvedge, the pieces are butted rather than overlapped, and synthetic joining tape with adhesive holds them from below with the fibres kept clear of the glue. Blades get changed often, because a blunt knife tears backing instead of cutting it.
• Edges and fixings. Perimeters are pinned at roughly 300mm to 400mm intervals into a prepared edge. Where turf meets concrete or pavers, adhesive does the work instead, usually over a thin foam underlay.
• Infill and brushing. Kiln dried silica sand at around 10 to 15 kilograms per square metre, worked in with a power broom. It ballasts the lawn, stands the blades up, shields the backing and makes the joins disappear. Under sanding looks fine on day one and matted by the following summer.

Independent testing and installer guides agree on where amateur jobs come undone, and it is not the laying. It is the base. Compaction and falls are the two things a weekend approach tends to compromise, and both take about a year to show themselves. If you are weighing the two routes on price, we set them side by side in our comparison of rolls bought off the shelf versus a trade install, and the full scope of what a Sydney turf installation covers step by step is worth reading before you take a quote apart.

Heat should change where you lay turf, not only what you buy

Heat is the objection that comes up first in Sydney, and it deserves to. Western Sydney University researcher Dr Sebastian Pfautsch has reported unshaded artificial turf reaching surface temperatures far above natural grass, including on days that were not especially hot by local standards. Those are his reported measurements rather than a fixed figure that applies to every product in every yard, and pile height, colour and infill all move it. The safe summary is the one manufacturers use themselves: it gets hotter than grass, and in full summer sun it can get very hot indeed.

What most people miss is that this is a decision made at the laying stage, not only at the shop. Where the turf goes, and where it deliberately does not, is the strongest lever you have:

• Map the shade before you map the lawn. Note where the fence line, house, pergola or a mature tree throws shadow through a summer afternoon, and put the turf where the shade lands rather than assuming the whole yard should be covered.
• Leave the hottest strip to something else. A west facing sliver that bakes from two o'clock onwards is often better as garden bed, paving under a sail or planting. A smaller synthetic lawn that gets used beats a larger one that nobody stands on in January.
• Plan a shade structure into the job, not after it. Footings for a sail or pergola are far easier to set before the base is compacted and the turf is bonded down at the edges.
• Keep a tap within hose reach. TigerTurf lists hosing the surface as one of the practical mitigations alongside shade, cooling infill and simply timing use for morning or evening. That is only convenient if the outlet is close to the lawn.
• Ask about yarn colour and cooling infill. Lighter colours run cooler, which is accepted physics. Products marketed as cooling yarns or evaporative infills may well help, but the percentage reductions quoted are the supplier's own claims rather than independently verified results, so ask for the data behind the number.

We treat the temperature question at length, including what the research does and does not establish, in our guide to how hot a synthetic lawn gets in full Sydney sun. If you are still sorting out the terminology while you compare products, the astro turf naming confusion is worth five minutes first.

Laying turf against re-turfing with natural lawn

The fair comparison is not synthetic turf against the tired lawn you have now, it is synthetic turf against doing the natural version properly, because re-turfing is the real alternative. Both jobs start the same way: strip the old surface, prepare the ground, level it. The difference is what happens after the last roll goes down.

A new natural lawn has to be watered in heavily to establish, and Sydney Water's Water Wise Guidelines are permanent rather than a drought measure. Lawns and gardens may be watered with drinking water only before 10am or after 4pm, whether by hand held trigger hose, sprinkler or watering system, with smart and drip irrigation allowed at any time. Fines are $220 for an individual and $550 for a business, and hosing down hard surfaces is not permitted. There is a 28 day exemption that lets newly laid turf be watered without those time restrictions, which tells you something in itself: the rules had to carve out an exception because establishing a natural lawn genuinely needs that much water. On day 29 the ordinary rules resume, for the life of the lawn.

Against that, a synthetic lawn has a higher up front cost and near zero water demand afterwards. Be careful with the long run comparisons circulating online, though. Some Australian suppliers publish ten year figures that make synthetic look overwhelmingly cheaper, while CHOICE has pointed out that the up front install is roughly double the natural equivalent. Those are different framings of the same decision and they should not be blended into a single number. And to say it once more plainly: there is no rebate, anywhere in Australia, for taking out lawn and putting in turf. The water case is avoided bills and avoided compliance hassle, nothing more.

The environmental side deserves both halves too. Recycling pathways for end of life turf do exist in Australia, but CHOICE has flagged a larger lifecycle carbon footprint than natural grass and up to 60 per cent higher runoff. That is a genuine trade off rather than a footnote. For the wider picture of products, tiers and what suits different yards, start with artificial lawn options across Sydney.
