Rockingham is a suburb of Perth, Western Australia, located 47 km south-south-west of the city centre. It acts as the primary centre for the City of Rockingham. It has a beachside location at Mangles Bay, the southern extremity of Cockburn Sound. To its north stretches the maritime and resource-industry installations of Kwinana and Henderson. Offshore to the north-west is Australia's largest naval fleet and submarine base, Garden Island, connected to the mainland by an all-weather causeway. To the west and south lies the Shoalwater Islands Marine Park.

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 · Rockingham Sand Plain

Coastal sand plain aquifer south of Cockburn. Shallow water table, generally bore-friendly substrate.

Bore prevalence: High
Water table: 1-4 m

Bore considerationsSalinity risk near coast - test EC before installing. Iron content typical for the system.
