Your guide to landscaping for australian homes - building guidance for Adelaide and South Australia.
Content scope
This guide has been reviewed for South Australia (Adelaide metro + regional SA). Building licensing, warranty, stamp duty and approval rules differ in other Australian states — verify against your local authority before acting.
Landscaping is usually the last line item on an Australian build, and it is often the one that gets squeezed. That is a mistake. A thoughtful landscape lifts kerb appeal, improves the way the home lives day to day, and protects the slab from erosion and water damage. It also has a real impact on energy use, with the right tree placement cutting summer cooling loads by ten to twenty per cent. This guide covers the decisions an Australian homeowner needs to make before signing a landscape contract, including paving and decking choices, retaining walls, lawn versus native garden trade offs, irrigation systems, and pool surrounds. Most numbers below are 2025 and 2026 Adelaide and broader Australian metro pricing for supply and install.

Key takeaways
Plain practical advice for Australian builds. No fluff.
Australian climate ranges from cool temperate in Tasmania and the Adelaide Hills through to hot dry in the inland and tropical in the north. Plant selection that ignores your zone will fail in the first hot summer. Check your council water restrictions and design around any permanent rules, especially in South Australia where surface water restrictions are common.
Adelaide reactive clay soils swell and shrink with moisture, which lifts paving and cracks slabs over time. Get a soil test (about $350 to $550), and budget for free draining sand or gravel under paving and for ag drains on sloping blocks.
A traditional couch or buffalo lawn uses around 700 to 1,200 litres of water per square metre per year in Adelaide. Native garden beds with mulched groundcovers use around a third of that. If you want lawn, keep it to a defined functional area.
Paving stones cost less per square metre (around $90 to $220 supply and install) and last longer than timber decking, but they soak up heat and can be uncomfortable underfoot in summer. Decking is cooler but needs annual oiling and replacement of fixings every ten to fifteen years.
Anything over one metre high in South Australia needs council approval and an engineered design. Use treated timber for cheap (around $280 to $420 per square metre face area), reinforced concrete block (around $450 to $700), or natural stone for premium (around $700 to $1,200).
A simple drip and sprinkler system with a battery controller runs around $1,500 to $3,500 installed for a typical 500 square metre block. Smart wifi controllers add about $250 to $450 but cut water use by another twenty to thirty per cent.
A deciduous tree on the north and west sides of the house shades windows in summer and lets winter sun through. Allow at least one metre of clear soil around each tree and check where underground services run before planting.
If you have a pool, the surround must be slip resistant (R10 or higher), heat tolerant, and chemical resistant. Travertine and porcelain pavers are the most popular Australian choices. Budget around $8,000 to $18,000 extra to landscape around a typical pool.

A small front yard refresh in Adelaide (turf, two trees, some shrubs and mulch) starts at around $3,500 to $6,500. A full landscape package on a new 450 square metre block, with paving, fencing, lawn, retaining and basic irrigation, runs $25,000 to $55,000. High end design led work with custom pools, stone retaining and mature trees easily passes $100,000. Always get itemised quotes and watch for soft costs like soil removal (around $80 to $130 per cubic metre to truck away), engineered drawings for retaining over one metre (around $1,500 to $3,500), and council fees if you are touching the verge. Supply only versus supply and install can mean a 35 to 50 per cent difference, so price both ways. Most landscapers will quote a fixed price after a site visit. Variation orders mid project are where budgets blow out, so finalise your design before they start.
