SOME COMMON MYTHS

Full cost pricing for infrastructure, including externalities. We can’t afford the costs of a grant-based system.
WATER SUPPLY AND THE DROUGHT
A drought, Australia should have expected (not a 1 in 1,000 years event)
Irrigation, urban & industrial use $
Unmanaged flow reducing effect
Water use efficiency savings
- 723 GL
Reduced water yield (Trees and dams)
- 600 GL
Salinity Interception Schemes
Add back 500 GL ?????
Increased groundwater use
Estimated nett reduction in mean river flow and allocations to irrigators
Actual amount used
Water that returns to the aquifer
Gross entitlement = 100 MLReturn = 50 ML
WATER LICENCES AND TRADING
Whereas the inhabitantsof South Australia are subjected to loses, heavy costs, and much perplexity, by reason that the laws relating to the transfer and encumbrance of freehold and other interests in land are complex, cumbrous and unsuited to the requirements of the said inhabitants, it is therefore expedient to amend the said Act
