Hiring a Landscaper
can mean four
very different things.

"Landscaper" covers everything from mowing the lawn to building a $40k retaining wall holding up your neighbour's yard. Same word, four different trades, four different sets of legal rules. The Sydney homeowner asking "is a 25% deposit normal?" doesn't realise the same NSW 10% rule that protects builders also protects them — if the job is over the threshold.

$5k

The NSW threshold where licensing kicks in.

10%

The legal maximum deposit. Not 25%. Not 30%.

Before we start

Soft landscaping is gardening.
Structural landscaping is building.

The word "landscaper" hides two very different jobs. Mowing, planting, mulching, light paving — that's soft landscaping and the rules sit closer to gardening. Retaining walls over 600mm, structural paving, drainage, decking attached to the house — that's structural landscaping and the rules sit closer to building.

The deposit law, the licensing threshold, the engineering certificate — all of them depend on which side of that line your job sits. The 10 questions below force the distinction into the open.

The retaining wall that fails in year four didn't have a structural engineer's drawing. That's the test, and that's the lawsuit.

How much should it really cost?

Landscaping pricing is two different markets — soft and structural. They share a job title and almost nothing else.

A landscaping quote should split into seven lines. Anyone packaging it into a single "$30k for the backyard" number is either a tiny scope or a setup for variations.

Seven lines a working quote shows

1Site prep + removal. Excavation, removing existing structures, tip fees.
2Hardscape. Paving, retaining, decking, edging. The expensive part.
3Drainage. Subsoil drainage, ag-pipe, surface stormwater. Skipped = future $20k repair.
4Soft landscape. Soil, mulch, plants, lawn. Often a separate sub-contract.
5Irrigation + lighting. If included. Separate trades sometimes — check.
6Engineering / certificates. Retaining over 600mm, structural paving, DA fees where applicable.
7Contingency + variation rules. What's open. What triggers a re-quote. $ ceiling on each.

Indicative ranges

AU 2026

Lawn install (50m² turf)	$800 – $2,500
Paving (30m² concrete pavers, installed)	$4,500 – $9,500
Retaining wall (under 1m · timber sleeper)	$300 – $600/m
Retaining wall (over 1m · engineered block)	$700 – $1,400/m
Backyard makeover (small · soft + light hardscape)	$15k – $40k
Full backyard build (structural + planting + irrigation)	$60k – $200k+

Indicative. Sloped sites, heritage, council overlays, premium materials = upper end.

How to tell a real one from a cowboy.

Landscaping cowboys love verbal scope changes and big deposits. The two combine to put $20k+ in their pocket before they've laid the first paver.

Red flags — in order of how often you'll meet them

!
Deposit over 10% (NSW residential over $5k)
The 10% statutory maximum applies to landscaping above the licensing threshold. 25% / 30% / 50% deposits are illegal and the loudest single warning sign.
!
No drawings, just "we'll work it out on the day"
A working landscaper produces a marked-up plan — site layout, levels, planting schedule. Without drawings, every variation favours them.
!
No engineer for the retaining wall
Any retaining wall over 600mm in most jurisdictions needs engineering. Anyone offering to build it without an engineer's drawing is offering you a future structural failure on your title.
!
No drainage in the quote
Hard surfaces + planting beds without subsoil drainage = waterlogging, root rot, retaining wall failure. Drainage is invisible and expensive. Cowboys skip it.
!
Cash discount
Same as every trade — no invoice trail, no warranty, no statutory protection. Particularly common in soft-landscaping crews.

The verification routine — 10 minutes, free

✓
State licence if over threshold. NSW: structural landscaping over $5k requires a Landscape Construction licence. QLD: above $3,300, QBCC.
✓
ABN on abr.business.gov.au. At least 12 months. Match the licence.
✓
Three reference jobs. Recent. Same scale + scope as yours. Drive past one. Hidden retaining wall failures show after 2–3 years.
✓
Public liability insurance. Certificate of currency. A landscaping crew on your site without PL is a risk you carry.
✓
Engineering certificate for any retaining over 600mm. Drawing + structural engineer\'s certificate.

Ask this, exactly

"Can you send your licence number, the engineering certificate for the retaining wall, and confirm the deposit is no more than 10%?"

When does a landscaper need a licence?

The licensing rules depend entirely on what kind of landscaping you're doing — and most homeowners don't realise the threshold applies to them.

NSWNew South Wales

NSW Fair Trading

Structural landscaping work over $5,000 requires a Landscape Construction licence.
Retaining over 600mm + drainage + paving = "structural."
Max deposit: 10%. The 25% pattern in r/sydney threads is illegal.
Check Service NSW.

QLDQueensland

QBCC

Landscaping work over $3,300 needs a QBCC licence.
Retaining walls over 1m require an engineer + QBCC-licensed builder.
Same threshold triggers Home Warranty Scheme.
Check qbcc.qld.gov.au.

VICVictoria

VBA

Domestic landscaping over $10,000 may need VBA registration.
Retaining walls over 1m: structural engineer + registered builder.
Above $16,000: Domestic Building Insurance required for structural works.
Check vba.vic.gov.au.

Half-time

The 25% deposit isn't normal. It's illegal.

Quote anatomy, the cowboy test, the licensing rules. The first three sort the structural landscapers from the cash-paid mowing crews. The next seven are how you tell the working operators apart from each other — and how the retaining wall holds in 2046.

When can you actually start?

Landscaping has its own season. Plants do best installed in autumn or spring. Concrete + paving needs dry weather windows. And anything structural needs council approval (DA or CDC for big jobs) — which can run 6–16 weeks before the first sod is turned.

A real start window.

Working landscapers are 6–12 weeks out for structural jobs. Soft jobs sometimes 2–4 weeks. "I can start tomorrow" on a big job is a warning.

A real build window.

Backyard makeover: 3–6 weeks. Full structural build: 8–16 weeks. With DA approvals: add 2–4 months upfront.

Weather + season.

Planting: autumn or spring. Concrete: not in 35°+ heat or driving rain. Honest landscapers schedule around the season, not against it.

Ask this, exactly

"What's a realistic build window for this scope, and is there a season we should aim for?"

What happens next, step by step.

1Step
Site visit + design brief
Levels, sun, soil, drainage, access. You describe what you want; the landscaper says what's possible.
2Step
Design + engineering
Site plan with levels, retaining engineering certificate, planting schedule, materials list.
3Step
Contract + 10% deposit
Letterhead, licence number, deposit ≤ 10%. Variation rules in writing. DA / CDC lodged if needed.
4Step
Site prep + structural
Excavation, retaining walls, drainage, paving, slabs. Engineer signs off any structural element before backfill.
5Step
Soft landscape + irrigation
Soil delivery, planting, lawn install, irrigation, lighting. Mulch goes on last.
6Step
Handover + plant care
Walk-through, defects list, plant care document (watering schedule, fertiliser, mulch refresh).

Architect, designer, structural, or maintenance?

Four professionals, four different price points. The single biggest cost mistake in landscaping is hiring the wrong one.

Lane 1

Landscape architect

Registered architect specialising in outdoor space. Design only, doesn\'t typically build.

Right when: $500k+ project, heritage / sloping site, you want design ahead of build.

Wrong when: small backyard, fixed budget, want one operator.

Lane 2

Landscape designer

Designs the garden, plant palette, hardscape layout. May coordinate trades or just sell the design.

Right when: you want a designed scheme to give to a builder, want plant + hardscape design coherence.

Wrong when: you want one operator end to end.

Lane 3 · most common

Structural landscaper

Licensed for structural work — retaining, paving, drainage. Builds from designs or basic briefs.

Right when: backyard makeover with hardscape, retaining, drainage. One operator end to end.

Wrong when: just want lawn + a few plants — overkill.

Lane 4

Maintenance / gardener

Mowing, pruning, planting, mulching. No structural work. Often no licence required.

Right when: ongoing maintenance, light plant work, soft landscaping only.

Wrong when: retaining over 600mm — they can\'t legally do it.

The expensive mistake is hiring lane 4 for a lane 3 job. The unlicensed gardener offering to "build a small retaining wall" doesn\'t have the engineering, the licence, the insurance, or the structural training. The wall fails in year four and you wear the cost — and the lawsuit.

Ask this, exactly

"Which lane do you operate in — and is my job above the structural / licence threshold in this state?"

Warranty — plants ≠ paving.

Landscape warranty splits into separate clocks for separate elements. Plants and lawn die naturally — a warranty here covers stock failure, not weather neglect. Paving cracks; retaining walls move. Each gets its own promise.

Layer 01

Statutory structural

6 years (NSW · VIC) / 6.5 years (QLD) on structural work above the threshold. Free, automatic.
Layer 02

Hardscape workmanship

Paving, retaining, drainage. Typically 12 months to 5 years. Must spell out callback triggers.
Layer 03

Plant + lawn warranty

Typically 90 days on plants, 30 days on lawn. Stock failure only — neglect / drought / pest exclusions.
Layer 04

Insurance-backed

HBC / HW / DBI applies above the state thresholds for structural work. Same as a builder.

Ask this, exactly

"Could you list the workmanship warranty on hardscape, the plant + lawn warranty, and the structural cover — in writing?"

Slope, drainage, soil.

Sydney landscaping is wildly site-specific — the same brief on a flat block costs half what it costs on a steep harbour-edge block. Three things drive the cost:

Slope
Anything over 5% gradient needs retaining + drainage. Steep blocks add retaining + access cost. Battle-axe blocks add machinery access cost.
Drainage
Subsoil drainage, ag-pipe, stormwater connections. Skipped = waterlogging, root rot, retaining failure. The invisible expensive layer.
Soil + rock
Sandstone under inner Sydney lawns means excavation rate doubles. Reactive clay needs more reinforcement. Soil test results drive the price.

Heritage suburbs add another layer — original planting, council overlay, heritage-approved materials. Premium suburb effect is real, but so is the actual extra work.

Ask this, exactly

"Have you done a soil + drainage assessment for my site, and what\'s in the quote for slope / rock contingency?"

Edge cases — get a second opinion for…

Retaining walls over 1m

Engineering certificate + licensed builder mandatory. Steep blocks may need stepped walls + structural drainage.
Drainage on hard sites

Subsoil + surface drainage on clay or rock sites is specialist work. Wrong drainage = retaining failure.
Tree work / removal

Council permits in many LGAs. Anything over 6m height typically needs an arborist + permit. Different trade.
Heritage Conservation Area

Heritage overlay restricts planting, paving materials, fencing. Council pre-approval needed.
BAL bushfire zone

Plant choice restricted, defensible space rules, mulch type restrictions.
Strata / townhouse

Owners corporation approval, common-property issues. Some strata schemes restrict planting.
Coastal / saltwater

Plant palette restricted, salt-resistant hardscape materials needed.
Pool integration

Pool fencing + landscaping interaction. Plant choices restricted within 1m of fencing.
Neighbour party walls / boundary

Boundary fencing law, neighbour notice for excavation near boundary, party wall agreements where applicable.

After they leave.

Landscape aftercare is unusual because the job is still becoming itself for the first 12 months. Plants take root. Lawn establishes. Drainage gets tested by the first heavy rain. A working landscaper schedules a 3-month and 12-month visit. A cowboy doesn\'t answer the phone after the final invoice.

Plant care document.

Watering schedule, fertiliser dates, mulch refresh, pruning calendar. Tailored to your plant palette.

3-month check-back.

Replant any plant losses under warranty. Check drainage performance after first heavy rain. Test paving + retaining.

12-month walkthrough.

Full review at the end of one growing season. Anything not thriving — discuss. The hallmark of a real landscaper.

6-year structural clock.

Statutory cover runs from completion. Keep contracts + photos + variation records + engineering certs.

Ask this, exactly

"What\'s your defects period, what does the plant warranty cover, and do you do a 3-month and 12-month check-back?"

If you've read this far

A landscaper who quotes the engineer\'s drawing before the planting plan is not a unicorn. It's the bar.

We can introduce you to landscapers in your area who already work this way — engineering for retaining, drainage costed in, deposit under 10%, plant care document at handover. No paid placement.
