In March 2011, successive leader John-Paul Langbroek stood down in favour of Brisbane Lord Mayor Campbell Newman.
As Opposition Leader he provided bipartisan support to facilitate the development of the coal seam gas industry in Queensland enraging many of his rural based parliamentary colleagues and Federal National Party Members.
He also delivered on promises made as Opposition Leader to develop regional planning legislation to facilitate the coal seam gas industry and protect landholders rights and prime agricultural land.
Following the Coalition's loss at the 2006 state election, standing leader Lawrence Springborg relinquished leadership of the opposition and the Queensland National Party.
On 18 September 2006, Seeney was endorsed as the new state National Party leader, with Maroochydore representative Fiona Simpson as his deputy.
The next day, with counting still underway even though the LNP's victory was beyond doubt, Bligh resigned as premier and state Labor leader and announced her retirement from politics.
Seeney served in an interim three-man cabinet with Newman and Nicholls until the full ministry was sworn in on 3 April.
Seeney holds a Masters degree in Business Management MBA from the University of New England and a certificate in rural business management from QUT and was the former Deputy Mayor of Monto a shire Council and chairman of the Burnett Inland Economic Development Organisation (BIEDO).
