Pauline Hanson and Bob Katter, two of Queensland's most controversial federal politicians, are joining forces ahead of next year's state election.

Mr Katter said the pair are burying their differences ahead of a drought tour across regional Queensland, starting Monday.

The "Drought Tour with Pauline and Bob" starts in Charleville on Monday, before wrapping up in Roma on Thursday.

While Senator Hanson's and Mr Katter's parties will remain separate, they will be using their respective representation in Parliament to put pressure on the government.
