Senator AYRES (New South Wales—Minister for Industry and Innovation and Minister for Science) (14:49): One thing that I can guarantee, Senator Babet, is that the cheapest form of energy, the cheapest electricity system for Australia, if you're remotely interested in certainty, affordability and reliability, is renewables backed up by storage and backed up by gas. That's the truth of the matter. That's why what's left of anyone with a sensible position coming from the opposition on the other side, I assume, is out there briefing journalists to say, 'We're desperately unhappy, actually, with the position that's been adopted by some of the characters over here.' The one thing you can guarantee will drive up electricity prices and drive away investment in Australian manufacturing capability in the energy system is the sort of policy incoherence we've seen over there. The PRESIDENT: Senator Babet, a second supplementary?
