Clive Palmer says Katter's Australian Party and independents will have to join his party if they want a free piggy-back at the next Queensland election.
The mining magnate says KAP Queensland parliamentary leader Ray Hopper should sign up with the Palmer United Party (PUP) if he wants to join forces.
"Well Ray should apply for party membership," Mr Palmer told AAP.
"He should join our party, they didn't poll very well.
"Tell him to get his application in."

KAP had a dismal showing at the federal election, with party leader Bob Katter only just expected to hold his seat of Kennedy with preferences.
The party failed to win any other seats, but Mr Palmer's fledging party seems to be on track for a lower house seat, and possibly two Senate spots.
However, Mr Palmer is also optimistic of securing a third Senate seat after West Australian votes are counted.
Mr Hopper said earlier that a coalition of PUP, KAP and the independents would pose a genuine threat to the Liberal National Party at the next state election.
"As it stands on today's figures we could win another seven or eight seats in Queensland if we do something along those lines," he told the ABC Radio.
Mr Hopper wanted to meet with Mr Palmer in the "very near future" to discuss the potential alliance.
Queensland Premier Campbell Newman said the potential marriage of sorts revealed more about Mr Hopper, who defected from the LNP earlier this year, than it did about any real political threat.
However, Mr Newman refused to comment about the PUP or its surprise success in the federal election.
Mr Palmer said on Tuesday evening the party would heavily target Mr Newman's government from now until the next Queensland poll.
He says PUP will contest the 2015 state election under the name the United Australia Party, which the Australian Electoral Commission refused to register for the federal poll.
Queenslanders couldn't wait for the next state election to punish Mr Newman for asset sales and outsourcing services, Mr Palmer said.
"If the 28 per cent primary vote I received contesting the seat of Fairfax at the federal election is replicated statewide, then we will mount a serious challenge to Campbell Newman's LNP government in 2015," he said in a statement.
The United Australia Party is already represented in the Queensland parliament by state leader Alex Douglas and deputy Carl Judge.
