Former Howard government minister Larry Anthony is planning a political comeback, making a tilt for the Queensland Senate seat being vacated by Barnaby Joyce.
Senator Joyce is giving up the senate spot in a bid to unseat Independent MP Tony Windsor in the NSW seat of New England at the September 14 election.
Mr Anthony, one of 12 candidates for the Senate preselection, was the NSW Nationals MP for Richmond from 1996 to 2004.
The son of former deputy prime minister Doug Anthony, he went on to be a minister in the Howard government.
Since exiting parliament, he has been a company director and pursued community interests.
The person chosen by the Liberal National Party for the position will serve for the balance of Senator Joyce's term, which is due to run out on June 30, 2017.
Other contenders include businessman Barry O'Sullivan, tourism executive Mary Carroll and scientist Dr Theresa Craig.
The LNP's 400-member State Council will meet in Mackay to select the party's candidate on May 25.
