The LNP has started day six of the election campaign splashing the cash, promising $1.3 billion worth of critical water infrastructure and dams across the state.

The funding will go towards five main projects in a bid to gain water security for Queensland.

The last regional dam built was Paradise Dam near Bundaberg, 12 years ago.

LNP leader Tim Nicholls said Labor hated dams and refused to progress them.
