Head of inquiry into Murray-Darling Basin plan questions its use of science

Commissioner says Murray-Darling authority seems to have approved plans it did not see as achievable

The commissioner heading South Australia's royal commission into the Murray-Darling Basin plan, Bret Walker SC, has repeatedly questioned whether the Murray Darling Basin Authority relied on the best available science.

Hearing evidence today from the Wentworth Group of Concerned Scientists, a group that includes some of Australia's most eminent environmental scientists, Walker quizzed the group on the twin themes of whether the MDBA was fulfilling its obligations under the Water Act and whether it was relying on the best available science.
