Senator CADELL (New South Wales) (14:40): Minister, a consortium of Australian universities found that another 12 million hectares of land is needed to host wind turbines, solar panels and transmission lines under your renewables-only energy plan. Has the government requested any advice? Senator Ayres interjecting— The PRESIDENT: Senator Cadell, I'm sorry. Please resume your seat. Senator Ayres, I need to hear the question, and your interjections are disrespectful and disorderly. Senator CADELL: Has the government requested any advice on how its energy plans will impact Australia's energy and food security, given that now 30 million hectares are being taken? The PRESIDENT: Minister McCarthy?
