Tasmanian senator Jacquie Lambie is without a senior advisor, with Rob Messenger quitting.
Mr Messenger moved to Tasmania to guide the party's campaign at the 2013 federal election.
Senator Jacquie Lambie has told News Corp she and Mr Messenger have had a falling out over policy and that he's 'moved onto bigger and better things'.
"Politics is constantly evolving as new information arises and Rob did not agree with the direction I am heading as a Senator.
"It wouldn’t be appropriate to discuss this further – I respect Rob’s right to privacy," Senator Lambie said.
Mr Messenger, is a former LNP member of Queensland's parliament and was an office holder and candidate for Clive Palmer's now defunct party.
