JEFF Seeney has called time on a 20-year career in state politics, announcing in Parliament last Thursday he had decided not to contest the next election.
The Callide MP, who served as deputy premier in the Newman government, said he planned to spend time with his grandchildren and seek new opportunities in the corporate sector.
Mr Seeney told the Central Telegraph the expansion of Callide under the proposed redistribution of state electorates, while not the reason for his decision, had been an appropriate time for him to assess his options.
"The electorate was made bigger, despite all of the predictions from all of the pundits, and to be honest (it) surprised me as well," he said.
Nominations have now been called for the LNP to choose a candidate to replace him on the next ballot.
While Mr Seeney would not be drawn on who, if anyone, he would support for preselection, he said the changes to his electorate represented an opportunity for a younger person to take on the job.
"Part of my decision was the recognition that I've been in this role for 20 years," he said.
"The role of a state member is not something you can learn overnight... this is an opportunity for a young person to do that."
He said there would be time for valedictories and reflection closer to the next election.
"I've had to make this decision now but I'm still the member for Callide for - I believe it will be - the next 12 months," he said.
"So it's full steam ahead, I'm doing the job as hard as I ever did.
"There'll be time... for me to give advice to the next person when they're elected, but that time's not now."
Mr Seeney admitted concerns the seat could be vulnerable to a resurgent One Nation did cross his mind as he made the decision.
"The redistribution gave me some comfort - notionally, at least on the last elections' figures, the seat is a little bit more attractive," he said.
"But One Nation is such an unknown that you can't take anything for granted.
"I think if you look at the areas that are in the seat now, they've been very sell served by the LNP and I hope people will see this as a strong LNP seat.
"But that's up to them."
