Thank you.
I just have time for one quick question.
The government is investing hundreds of millions of dollars in the parliamentary precinct, and I've seen some of the historic buildings and the advantages. We have access to our windows, which are basically a single-pane window, but we get fresh air, so that's the trade-off: the fresh air versus the sealed-in, recirculated air.
Have you looked at the precinct here and the numbers, what we're at right now, and once it's completed what kinds of savings and energy efficiencies and greenhouse gas emission reductions there will be?
