Mr LITTLEPROUD (Maranoa—Leader of the Nationals) (14:52): My question is to the Prime Minister. In the past 12 months, sheep prices across the nation have plummeted by up to 70 per cent. Industry confidence has collapsed and farmers are being forced to the wall as a result of the government's announcement about shutting down the live sheep export industry. Did the government undertake any economic modelling on the impact of banning live sheep exports— Government members interjecting— The SPEAKER: Order! There's far too much noise on my right. I'm going to ask the Leader of the Nationals to state that question again. The member for Fremantle will cease interjecting. I want to make it clear at the beginning of question time this week that no-one is to interject during a question. The Leader of the Nationals has the call. Mr LITTLEPROUD: My question is to the Prime Minister. Prime Minister, in the past 12 months, sheep prices across the nation have plummeted by up to 70 per cent. Industry confidence has collapsed and farmers are being forced to the wall as a result of the government's announcement about shutting down the live sheep export industry. Did the government undertake any economic modelling on the impact of banning live sheep exports before announcing the shutdown?
