Evaluating progress toward the Goal TERM Water in the Australian Economy By 2032: 5 Million more people 34% increase in irrigation efficiency 22% increase in household efficiency 15% decrease in rainfall ± water recycling ± seawater desalination ± rural water trading Shadow price $kL Perth$10.50 $5.80 $4.20 $3.80

Impacts valued to date Some of the research impacts that the Flagship has valued: Identified an additional 20 Gigalitres per annum of recoverable water from Perth primary groundwater supply (saving about $200m in capital works); Climate analyses underpinning accelerated investments in new water infrastructure in WA and Vic of $500M and $50M. Identified irrigation water savings of about 295 GL in the Murrumbidgee catchment (worth about $200m on the permanent trade market).
