The Liberal National Government changed the methodology for calculating the operating subsidy in the 2016/17 budget without reviewing the potential impact on steps and classes, resulting in some country towns such as Carnarvon becoming over-cost recovered. However, 89% of water delivered to residential customers is billed at or below the metropolitan equivalent price.
Further, for 2019-20 in total country water supply schemes are under cost-recovered by 49%, including; Coral Bay, Denham, Onslow and Wiluna.
