Mr TED O'BRIEN (Fairfax) (14:47): My question goes to the Prime Minister. The government's budget has disproven the RepuTex modelling behind Labor's Powering Australia energy plan. I note that over the weekend the Department of Climate Change, Energy, the Environment and Water removed reference to that modelling from its website. Since Treasury and the department don't trust Labor's modelling, why should the Australian people? Opposition members interjecting— The SPEAKER: Order! Members on my left will cease interjecting. The member for Fairfax was heard— Mr Littleproud interjecting— The SPEAKER: The Leader of the Nationals! The member for Fairfax was heard in silence, so will be the minister. I give him the call.
