Bob Katter's newly-formed Australian Party aims to win more than 20 seats in Queensland's next election after merging with the Queensland Party.
The newly created Australian Party will "bloody" the major parties founder Katter said today.
He joined Queensland Party founder founder Aidan McLindon to announce the merger of their two groups.
Both said Mr Katter's experience and Mr McLindon's youth presented a "formidable combination".
Mr Katter said there was "a lack of logic" in parties with the same policies fighting each other.

"Surely we should be punching away at the two parties in there,"Mr Katter told reporters in Brisbane.
"If you think there's not going to be blood on the carpet, you're making a terrible, bad mistake."
Mr Katter, who will be Australian Party's federal leader, said it was "more than feasible" that the new party would win more than 20 seats at the next state poll, due by March 2012.
He vowed to be a force beyond regional areas, promising to campaign the length and breadth of Queensland wherever good candidates could be found.
"We will be winning seats in Brisbane," Mr Katter said. "I can tell you that right now."
Mr McLindon, who will be state leader, said some in his party had been disappointed with the merger and some had described Mr Katter as "a cut snake".
But he said Mr Katter had stood the test of time and he was proud to be working with him.
"Cut snakes last for 39 minutes," Mr McLindon said. "This good man's lasted for 39 years, so he must be doing something right.
"He speaks from the heart and he gets it right nearly all of the time."
Mr Katter, a federal MP representing the electorate of Kennedy since 1993, founded the Australian Party in June. Mr McLindon's Queensland Party was set up last year.
Liberal National Party (LNP) leader Campbell Newman said he was concerned the new force could see Labor returned to power and asked voters to support the LNP.
"Mucking around with minor parties and independents will lead to the same disastrous situation we have at the federal government at the moment," he told reporters on the Gold Coast.
