Premier Dominic Perrottet insists the federal government should fund to raise the Warragamba Dam wall despite Ben Fordham revealing otherwise.

The NSW Premier is now insisting the state will fund the $1.6 billion project on its own if the Prime Minister won’t share the cost.

He told Ben Fordham the wall will be raised next year.

“We will have the final reports conducted and submitted to the federal government … very shortly.”

But Ben wants to know an exact timeline for the build.
