Landscape & Garden Design in Australasia

Australian design works with the bush rather than against it: structure from eucalypts and banksias, colour from the dry-country flora, and a house that opens to the garden. Fire and water set the rules.

Practice in this climate

Designers start with a bushfire attack level assessment and a water strategy, then place the garden to shade the house and screen the neighbours. Native planting is grouped by soil and drainage, with a low-fuel zone near the building. Lawns are shrinking; gravel, mulch and dense groundcover take their place.

Watch outA eucalypt within 10 m of the house is a maintenance and fire decision, not just a shade decision.

The year here

SeasonWhat to do
AutumnPlant natives and trees; mulch before winter.
WinterPrune, plan firebreaks, and order spring planting.
SpringPlant perennials, mulch, and check irrigation.
SummerShade, water new plants, and reduce fuel near the house.

Constraints

  • Phosphorus-sensitive proteoids (banksia, grevillea, waratah) are killed by ordinary fertiliser; use low-P products.
  • Bushfire is a design parameter: defendable space, low-fuel planting and water access come before aesthetics.
  • Summer drought and water restrictions are normal; native and Mediterranean species outperform thirsty exotics.

FAQ

What grows best for garden design in Australasia?

The palette lists 14 taxa that match this discipline in the region; start with Gum, Bloodwood, Wattle. Each entry names the role it plays and why it suits this climate.

When is the planting window in Australasia?

September to April. Autumn is the first move: Plant natives and trees; mulch before winter.

What is the main risk here?

Phosphorus-sensitive proteoids (banksia, grevillea, waratah) are killed by ordinary fertiliser; use low-P products.
