At its 2009 state convention,the LNP overwhelmingly backed a call from delegates to have an independent body draw up an upper house and take it to a referendum if it won office - a position backed by the party's state council in November that year.
Mr Seeney said the LNP's 2009 position had been superseded by support for State Parliament's new committee structure,developed with bi-partisan support.
"I think the motion in 2009 was probably an expression of a desire to see something change in the Queensland Parliament,"Mr Seeney said.
"Everybody wanted to see some more accountability and more input into legislation."
Mr Seeney said the LNP now believed that the new committee structure should be given time to work,and would not take the upper house concept to a referendum.
"I think that that expression of a desire for change has certainly been superseded by the new committee structure,"he said.
State Parliament will this month discuss an"upper house"for Queensland when Beaudesert MP Aidan McLindon's model for a"People's House",using the state's mayors as MPs,will be debated and voted on.
