Speaking to Deborah Knight, Minister for Mental Health and Nationals member of the upper house Bronnie Taylor presented a united front.

“We are a coalition partner, but we are our own party, and when we decide that these things are the most important thing for our communities … [we] stand with them.

“That’s why they vote for us. That’s why we have the Nats.”

Asked whether she’d be prepared to leave the state cabinet and move to the crossbench, the Minister said she’d “do what needs to be done”.

“I stand united with the National party, and all of my colleagues feel the same.

“Our party room is completely behind John Barilaro, but this is a decision that we have all made together.

“We need to be listened to.”
