Indeed. Thank you for that question.
There are a number of categories of projects, I would say, within that capital envelope. A very large one is the government's office portfolio. It's close to seven million square metres of offices. We're doing an active review, in light of all the changes in the workplace, of our future needs for that space, but that space requires ongoing rejuvenation, renovation and replacement, so that's one big area.
We have other capital projects as well in what we call “engineering assets”. This would be work on bridges and other assets across the country. We have the plan of work that was noted on the parliamentary precinct, which is a very large undertaking with multiple phases in the work.
Those are some of the categories of work.
I don't know if my CFO, Wojo, wants to add anything on the nature of the ups and downs of the capital envelope.
