The funding was part of a deal with independent Member for Kennedy Bob Katter to gain support for the coalition in parliament.

“The agreement will support the continued stability of the government and us getting on with the job,” Mr Morrison said in a statement.

Queensland Natural Resources Minister Dr Anthony Lynham said he was seeking more details on the Federal Coalition’s dam plans for North Queensland.

“Let’s be clear: We are always keen to see Federal money heading for Queensland,” Dr Lynham said.

“We are just not sure what is the next step, or what is expected of any Queensland government or statutory bodies.

“The Palaszczuk Government has already funded an initial investigation into the Hughenden Irrigation Project with the Flinders Shire Council and an initial business case of the $5.35 billion Hells Gate project has identified significant challenges.

“Usually, detailed business cases are conducted, sometimes by independent bodies like Building Queensland, before governments commit to major, long-term infrastructure like dams.”

In  a letter to Mr Katter the PM wrote:

“I seek your continued agreement to support the Government on issues of confidence and supply, as well as all motions procedural or otherwise and second reading amendments that attempt to cause disruption to the good order of the House.

“As a result of meeting with representatives from the area, it is a decision of the Government to advance the interests of the constituents of Kennedy and agree to the funding of up to $180 million for the Hughenden Irrigation Scheme project and up to $54 million for the Hells Gates Dam Stage 1, Big Rocks Weir.

“The funding for these projects is for all necessary regulatory, compliance, pre-construction and capital works.”

Mr Katter agreed to the proposals outlined “with appreciation”.
