Senator ROBERTS (Queensland) (16:03): My question is to the Minister representing the Minister for Climate Change and Energy, Senator McAllister. The government has ruled out adding nuclear electricity to our energy mix based on the government's calculations showing a higher cost of nuclear energy as against wind and solar. Minister, can you please inform the Senate of the levelised cost of generation of wind, solar and nuclear that informed the government's position? The PRESIDENT: Thank you, Senator Roberts. I will just remind you that questions need to go to ministers, not assistant ministers, so I'm directing the question to Minister Gallagher.
