BUNDAMBA MP Jo-Ann Miller says Bruce Flegg did the right thing - but Campbell Newman should have sacked him first.
Dr Flegg resigned on Wednesday after a staffer raised questions about the accuracy of the minister's lobbyist register.
Yesterday he was replaced by former NRL referee and Springfield school chaplain Tim Mander as Housing and Public Works Minister.
"The premier has lost authority within his own government, otherwise he would have acted before Dr Flegg himself did," Mrs Miller said.
"Dr Flegg has done the right thing. But it is the premier who should have brought down the curtain on this episode of the ongoing soap opera that is the LNP government."
LNP Member for Ipswich West Sean Choat said Mrs Miller's comments were "as predictable as they are inaccurate".
"I am personally disappointed at the resignation of Dr Flegg," Mr Choat said. "Dr Flegg acted in a very courageous way. Let's put this into perspective: the resignation was the result of administrative failures in the minister's office - nothing he did.
"Consider the previous Labor Government and the litany of scandals, maladministration and incompetence that wasted billions of dollars and not one minister was sacked or resigned their position.
"The premier said ministerial accountability was an unconditional part of being in cabinet. The minister's resignation demonstrates how seriously it is taken."
Ipswich MP Ian Berry said Mrs Miller "doesn't have a leg to stand on talking about accountability" when not a single person was sacked or resigned over Labor's health payroll debacle.
"Unlike Labor's absolute contempt for the tradition of ministerial responsibility, the LNP has set high standards of accountability and responsibility in government," Mr Berry said.
