Some of the best-quality groundwater in Australia underlies the upper and lower south-east of South Australia and parts of south-western Victoria.

Underground water in some areas has collapsed and water quality is deteriorating, putting at risk not only a fragile natural ecosystem but a $5bn regional economy.
