Perth Landscaping Cost Calculator.Know what it should cost in Perth.

In Perth, landscaping typically costs between $6,825 and $78,750 in 2026, with most projects landing around $23,100. Pricing varies with size, finish level, complexity and your specific site.

A small soft-landscaping project takes 1–2 weeks. Larger projects with retaining walls, paving and structures can take 6–12 weeks.

Not strictly — but for projects over $20k, a designer typically saves more than they cost by avoiding rework and ordering correctly.

Planting, turf and garden beds generally don't need approval. Retaining walls above a height threshold (commonly 600 mm to 1 m depending on your state), significant cut and fill, and structures like pergolas or decks often do. Check with your council before work starts — retrospective approval is slow and expensive to obtain.

Most quotes cover site preparation, materials, labour and rubbish removal for the scope described. Common exclusions are soil disposal from excavation, drainage upgrades, electrical and plumbing connections for lighting or irrigation, and ongoing maintenance. Ask each contractor to itemise inclusions so you're comparing like for like.

Slope, soil type and access matter more than garden size. A sloping block usually needs retaining and drainage work before anything decorative starts, and rocky or reactive clay soils add excavation time. Tight access means machinery can't get in, so material is moved by hand — which adds significant labour cost.

In most states, structural retaining walls above the exempt height must be engineered and built by a licensed contractor. Any electrical work for garden lighting must be done by a licensed electrician, and connecting irrigation to mains water requires a licensed plumber. General planting, turfing and paving don't require a licence, though many states require landscape contractors to hold a building licence once the job value passes a threshold.
