A small cohort of Queensland politicians want to boot Brisbane.

By that they mean cut the state in half and let the north rule itself with its own economy, parliament, name, flag and constitution.

Robbie Katter, his fellow Katter's Australian Party MPs Shane Knuth and Nick Dametto, One Nation's Stephen Andrew and independent MP Jason Costigan, say it is time to secede.

"We all know why we should do this, now let's work together and get this done," Mr Dametto told a small crowd of backers in Townsville on Tuesday.
