Australind Water Hardness & Quality Report (2026)

Australind's drinking water is supplied by the Water Corporation via the South West Water Supply Scheme, drawing from Wellington Dam on the Collie River and supplemented by Harvey aquifer groundwater extraction for the Harvey Shire LGA on the Leschenault Inlet coastal strip in Western Australia. Water hardness in Australind is measured at 152.5 mg/L — classified as moderately hard — within the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Australind — a fast-growing lifestyle coastal community on the Leschenault Inlet adjacent to Bunbury, known for the tranquil Leschenault Estuary Nature Reserve, the heritage Australind village precinct, and the Bingham Road wetlands — receives a moderately hard supply reflecting the blend of Wellington Dam surface supply and local coastal plain groundwater in the south-west WA distribution system.

Australinds' moderately elevated hardness reflects the blending of Wellington Dam Collie River catchment supply — drawing from Precambrian Yilgarn Craton granite and laterite terrain that produces softer surface water — with supplementary Harvey coastal plain aquifer groundwater that accumulates moderate calcium, magnesium, and saline ions from the Quaternary to Tertiary sedimentary coastal plain formation. The mixed source supply classification at TDS 379.4 mg/L reflects this blend of soft Precambrian granite surface supply with more mineralised coastal plain groundwater characteristic of south-west WA water supply systems.

Australinds residents face moderate limescale build-up on taps and in kettles — descaling every three to four weeks is typical. Hot water systems benefit from annual inspection. Under WA water restrictions, garden irrigation is limited to two days per week in summer. The low lead reading (0.002 mg/L) is reassuring. The Water Corporation provides water quality information at watercorporation.com.au, with all ADWG health standards consistently met. The moderately hard supply is typical for the south-west WA coastal plain communities served by the South West supply scheme.
