I'd have to disagree significantly with my colleague about the transparency aspect. I think we're at a low point in recent years in terms of transparency around procurement, and committees like this remain one of the few venues by which government and government officials communicate about what's happening with multiple tens of billions of dollars' worth of taxpayer investments.
During the pandemic, I've seen things like updates to the defence capabilities blueprint, which have been touted as a transparency exercise, effectively stopped for reasons that I don't really understand, because you can do web editing from home, as far as I can understand.
