I can respond to the parliamentary precinct aspect.
There are challenges with heritage structures, of course, but I think we can move beyond trade-offs and zero-sum games and align by prioritizing heritage, sustainability, accessibility, and security. Much of that comes down to having a clear plan of where you're trying to get to, and understanding the buildings, and understanding what the character-defining heritage elements are. Then you can make strategic choices about how you can achieve sustainability elements. We've already done some of that, in part, in the precinct.
We're already exceeding our targets for GHG emissions. For example, when it moves into restoration, we are looking at making the Centre Block a flagship project of sustainability. There are significant improvements that have already been made. In this building, for example, there are solar panels on the roof. There is heat recapture. We have energy-efficient building systems, and on and on. The green wall that you would have seen as you came in and green roofs have been installed throughout the precinct.
