"We will make sure that we have covered our base right across Australia," he said.
"We are pulling no punches and giving people an alternative."
However, Mr Katter has admitted the party has so far attracted less than half the potential candidates that it needs.
Mr Katter also says he will make an exception for South Australia, depending on the wishes of independent Senator Nick Xenophon.
"We would be preserving that relationship and if Nick wants us to run there, we will be running there," he said.
"But if not, we will be throwing our whole-hearted support behind Nick Xenophon.
"We don't agree with Nick on everything but the really important issues we've fought side-by-side."
"The debacle that we've seen in Canberra over the last three years has been the result of fringe parties and independents having control of parliaments," he said.
"I don't think any Australian would suggest that what we've seen in Canberra over the last three years is a situation we want to see repeated.
"It's been in nobody's interest."
