Landscaping is one of the last big line items in a Melbourne build - and one of the least regulated. Prices vary 2x for the same scope, quality gap between the top 8-10 Melbourne operators and the rest is huge, and the biggest Melbourne risk (drainage) rarely appears in a quote. This guide walks through the real all-in ranges for soft-scape and hard-scape, the Victorian Building Authority (VBA) approvals you actually need, and how to compare Melbourne landscaping quotes on a shared inclusions sheet.
Melbourne landscapers price in three buckets: soft-scape (lawn, garden beds, planting, irrigation), hard-scape (paving, walls, decks, driveways, drainage) and structures (pergolas, screens, water features). Soft-scape is where the margins are lowest and the quality difference is smallest. Hard-scape is where the money and the risk sit — this is where you need engineered detailing, particularly for retaining walls over 900mm.
Reactive basalt clay across most of metro Melbourne moves seasonally. Paving laid on unstabilised clay will heave and gap within 24 months. Retaining walls without proper drainage weep-holes and geo-fabric will bulge or fail. The four Melbourne-specific line items every quote should carry: (1) compacted road-base under all paving, (2) ag-drain behind every retaining wall over 600mm, (3) soil-improvement in garden beds (not just topsoil dump), (4) a proper irrigation controller with drip lines — not popup sprinklers on clay.
Retaining walls over 1m usually trigger development approval. Fences that double as retaining walls need a neighbour consent under the Fences Act (SA) or Fences Act 1968 (VIC). Structures like pergolas within a certain setback of the boundary trigger their own approval. Your landscaper should own the Victorian Building Authority (VBA) lodgement, not you. If they say "no approval needed, don't worry", you're the one who gets the council letter.
Landscape is unregulated (no mandatory licence for pure soft-scape) but hard-scape work above $12,000 in SA and above the DBI threshold in VIC needs an appropriately licensed / registered builder. Insist on:
Full backyard refresh: 4-8 weeks on-site. Soft-scape only: 1-2 weeks. Full hard-scape with retaining and drainage: 8-14 weeks. Add 4-6 weeks for design + engineering before crews arrive.
