Lessons from Australia’s water markets

• Can work in complex systems, including across boundaries

• Have enabled private investment and supported irrigation

• Large benefits to agriculture, urban areas and environment

• Require

- good water planning and effective cap on water extractions

- specifying, monitoring and enforcing entitlements

- water registers, metering and accounting

• While costly, these fundamentals support good water management

• can be introduced incrementally and participants learn quickly
