Hillarys is a northern coastal suburb of Perth, the capital city of Western Australia, in the local government area of the City of Joondalup. It is part of the Whitfords precinct, and is located 21 km north-northwest of Perth's central business district via Mitchell Freeway and Hepburn Avenue.
Soil zone · Spearwood Sands
Yellow-brown sands over Tamala limestone at varying depth. Free-draining with mildly alkaline pH from the underlying limestone.
- Drainage
- High
- Water retention
- Low
Irrigation strategyModerate cycles work well. Plant selection should suit alkaline pH. Standard pop-up and rotor systems are effective.
Installation notesLimestone often hit at 300-800mm depth - plan trenching accordingly. Rock saw or hand pick may be required. Consider above-ground manifolds where rock is shallow.
Groundwater · Gnangara Mound
Large unconfined superficial aquifer covering most of Perth north of the Swan River. Primary garden-bore source for the northern suburbs.
- Bore prevalence
- Very high
- Water table
- 1-5 m
Bore considerationsDWER bore licence required. Most properties on sandy soils have viable shallow bores. Iron staining is common - filtration often needed. Subject to abstraction limits and metering rules.
