Real Perth Landscaper Quotes — Cost Guide
Three Perth landscapers quoted the same backyard — here's what each charged
We sent the same 180m² Perth backyard scope — paving, lawn, planting, retic, basic lighting — to three Perth landscapers and asked each for a written quote. The numbers came back at $14,200, $19,400, and $22,800. That's a 60% spread on what should be a similar job, and the surprising part isn't that the highest quote was the most expensive. It's that the lowest quote, properly scope-matched, was actually the most expensive once you added back what it omitted.
The job brief — what we asked for
To make this comparison meaningful, all three landscapers got the same brief, the same site visit window, and the same scope description. Here's the precise specification we provided.
Site: 180m² flat backyard in Willetton (south of the river, mid-range suburb, sandy substrate, no slope, no existing retaining). 1990s build, single-storey home.
Existing condition: Tired buffalo lawn yellowing in patches. 1990s concrete patio with surface cracking. Six-plant border on one side, four plants dead, two failing. No working irrigation.
Scope requested:
- Remove existing patio and dead lawn
- New brick-paved alfresco zone, 35m²
- New Sir Walter buffalo turf, 90m²
- Mixed native garden beds, 30m² total
- Reticulation system: full coverage, 4-station
- Soil amelioration for sandy substrate
- Mulch finishing throughout
- Basic mood lighting (4 path lights, 2 feature lights)
- 4–6 week project window acceptable
What we did NOT specify: Brand of pavers, specific plant species (left to landscaper recommendation), or lighting brand. We wanted to see what each landscaper would propose within an identical scope.
How quotes were sourced: Three landscapers from operators servicing the Willetton area, all licensed and trading 5+ years. Quotes received within 10 working days of site visit. Landscaper identities have been anonymised at their request.
Quote A — Premium designer-builder ($19,400)
The "design-first" operator. Includes a formal design phase before construction.
| Line item | Detail | Cost |
|---|---|---|
| Design consult + plan | 90-min site, sketch plan, plant list | $1,200 |
| Demolition + dump fees | Patio break-out, lawn lift, removal | $1,400 |
| Soil prep + amelioration | 180m² treatment | $1,500 |
| Brick paving | 35m² premium brick paver, hand-cut detail | $4,725 |
| Sir Walter turf | 90m² supply + install | $3,150 |
| Garden beds + planting | 30m² mature stock, designer selection | $3,600 |
| Reticulation install | 4-station, smart Wi-Fi controller | $2,400 |
| Mulch + edging + lighting | Pine bark, steel edging, 6 lights | $1,425 |
| Total | $19,400 |
Strengths. The design phase formalises scope before construction starts — fewer mid-job surprises and changes. The smart Wi-Fi controller adds about $300 over a standard controller but lets you adjust watering remotely. Mature plant stock means immediate visual impact rather than waiting 12 months for plants to fill out. 12-month plant warranty included.
Weaknesses. Highest design-phase cost in the comparison — for a relatively standard suburban backyard, $1,200 of design work is more than some homeowners want to pay. "Mature stock" is undefined in the quote; worth getting specific about plant size before signing.
Quote B — Mid-market owner-operator ($22,800)
The "I do everything myself" operator. No design phase, daily on-site supervision, longer warranty.
| Line item | Detail | Cost |
|---|---|---|
| Site visit + sketch | Free | $0 |
| Demolition + dump fees | Patio break-out, lawn lift | $1,800 |
| Soil prep + amelioration | 180m² thorough treatment | $1,800 |
| Brick paving | 35m² standard brick paver, hand-cut | $5,250 |
| Sir Walter turf | 90m² supply + install | $3,600 |
| Garden beds + planting | 30m² mid-range native selection | $4,200 |
| Reticulation install | 4-station, standard controller | $2,800 |
| Mulch + edging + lighting | Pine bark, brick edging, 6 lights | $2,400 |
| Project management | Owner-operator on-site daily | $950 |
| Total | $22,800 |
Why higher than Quote A despite no design phase. Owner-operator pricing typically reflects more direct labour cost — no margin on subcontractor markups. Brick edging chosen for unified visual look (versus Quote A's steel) — more labour-intensive. Higher demolition cost reflects more thorough dig-out and base preparation. Project management line is the daily on-site premium.
Strengths. Single point of contact, owner accountability, daily site presence. 24-month workmanship warranty (longest of the three). Strong portfolio of comparable Perth jobs.
Weaknesses. No formal design phase — scope agreed verbally on site, which can lead to scope ambiguity. Higher cost without obvious premium in materials.
Quote C — Budget operator ($14,200)
The trap quote. Looks like the obvious winner. Isn't.
| Line item | Detail | Cost |
|---|---|---|
| Site visit + sketch | Free | $0 |
| Demolition + dump | Combined removal | $1,200 |
| Brick paving | 35m² standard brick | $4,725 |
| Turf | 90m² kikuyu (not Sir Walter) | $2,250 |
| Garden beds + planting | 30m² basic plant selection | $3,150 |
| Mulch + edging | Pine bark, no edging detail | $800 |
| Path lighting | 2 path lights (not 6 as briefed) | $200 |
| Project management | Self-managed | $0 |
| Total as quoted | $14,200 |
What's missing or downgraded from the brief:
- No reticulation in this quote. Should add $2,400. When asked about it: "we can add that, it'd be $2,800 extra." Note the upcharge versus the others' baseline.
- No soil amelioration. Should add $1,500. Critical for Perth sandy soil — without it, plant beds fail within 18 months.
- Kikuyu instead of Sir Walter buffalo. Saves $1,350 upfront but kikuyu is less drought-tolerant under Perth's two-day-per-week water roster. Many Perth homeowners regret the substitution within two summers.
- 2 path lights instead of 6. Incomplete to brief — only one-third of the requested lighting.
- No project management line item. Translates to ad-hoc subcontractors and limited oversight.
- No warranty period stated. Always a red flag.
Normalised total if you add back what's omitted to match the brief: $14,200 + $2,800 retic + $1,500 soil prep + $1,350 Sir Walter upgrade + $800 (4 additional lights) = $20,650.
So Quote C, scope-matched, is actually $1,250 MORE than Quote A — but presented as $5,200 cheaper.
The lesson — how to compare Perth landscaping quotes
Scope-match before dollar-comparing. When three landscapers quote different totals on the same job, the cheapest one is almost always omitting scope rather than truly being cheaper. The question isn't "which quote is lowest?" — it's "which quote actually includes everything I asked for?"
Red flags in cheap Perth landscaping quotes:
- No reticulation line item (or "we can add that for $X" deferral)
- No soil amelioration for the sandy substrate
- Kikuyu substituted where you specified Sir Walter buffalo
- No warranty period stated
- No project management or supervision detail
- Single-line quote without itemisation ("just $X for the whole thing")
Questions to ask every Perth landscaper before signing:
- Is reticulation included? What spec — number of stations, controller type?
- How are you preparing the soil for the sandy substrate?
- What warranty do you provide on plants and workmanship?
- Will you or a foreman be on-site daily, or is it subcontracted out?
- Can you show me three completed Perth jobs of comparable scope?
When the higher quote is actually cheaper. Quote B at $22,800 looks expensive against Quote C at $14,200, but Quote B includes everything in the brief and has the longest warranty (24 months versus none stated). Cost-per-year-of-life on the work often matters more than the upfront number. A $19k landscape that lasts 15 years is a better deal than a $14k landscape that needs $5k of remediation in year three.
To sanity-check any quote line by line, the full Perth landscaping pricing table has every component priced individually. If a quote's line item differs from the typical range by more than 30%, ask why.
For readers considering DIYing parts of the job to save money — there's a separate calculation around tool hire, time, and licensed-work requirements that matters as much as the labour cost. See DIY vs hiring a landscaper in Perth →
FAQs about Perth landscaping quotes
Why do Perth landscaping quotes vary so much?
A 60% spread between Perth landscaping quotes for the same scope is common, and the variation almost always comes down to scope omission rather than genuine market price difference. The cheapest quote often excludes reticulation ($2,000–$3,000), soil amelioration for sandy soil ($1,000–$2,000), or substitutes lower-grade materials (kikuyu turf instead of Sir Walter buffalo). Once you scope-match all quotes to the same inclusions, the spread typically narrows to 10–15% — a normal range for differing labour rates and material sourcing.
What's typically MISSING from a cheap Perth landscaping quote?
The four most common omissions in cheap Perth landscaping quotes are: (1) reticulation system installation, (2) soil amelioration for Perth's sandy substrate, (3) waste removal and dump fees, and (4) workmanship warranty period. The lowest quote we received on a 180m² Willetton backyard came in at $14,200 — but adding back the four omitted items brought the true scope-matched total to $20,650, more than the mid-range quote of $19,400.
How many quotes should I get for a Perth backyard landscape?
Get three. Two quotes is too few to spot scope-omission patterns. Four or more wastes everyone's time and dilutes the landscaper's interest in winning your job. When sourcing three quotes, brief each landscaper identically — same site, same scope description, same timeline. If two of three quotes cluster within 15% and one is dramatically lower or higher, you've identified the outlier worth scrutinising.
