The entire Murray-Darling Basin will be policed by the new Inspector-General to ensure every region around the Basin gets their fair share of water.
The new role will see someone hold stronger powers to assure transparency, scrutiny and integrity around the use of the Basin.
The Inspector-General's role includes checking water recovery and delivery of water efficiency projects; monitoring compliance; investigating suspected water theft across the Basin; creating annual reports for the Minister for Water Resources; and engaging with the community about implementing the Basin Plan.
There has not been someone appointed to the role yet, but Mike Keelty is currently acting as interim Inspector-General.
Senator for South Australia Anne Ruston said the Inspector-General would be a statutory position which would give them power und the Commonwealth Water Act 2007.
"The drought has shown just how valuable water is in Mayo and this will make sure we get our fair share," Senator Ruston said.
"The Inspector-General will also make sure the MDBA, Commonwealth and all states live up to their responsibilities in delivering the Plan as agreed and to ensure the laws governing water use are followed."
Minister for Water Resources David Littleproud said communities, farmers and environmentalists across Mayo could be assured the Basin Plan was being delivered as promised.
He said having the Inspector-General look after the Basin was an "integrity measure".
"The public needs to know the Basin Plan is delivering the water it was intended to, and farmers need to know the Plan is working for as it should," Mr Littleproud said.
"The Inspector-General can investigate suspected water theft, collect evidence and supply it to the authorities.
"Offices and staff to support the Inspector-General will be established in both the northern and southern basin."
