Ah yes, the QVB. As I kid, I rode with my dad in his truck delivering stuff around Sydney on school holidays and remember the QVB when it was derelict, shored up with corrugated iron sheeting and sheets of ply. There was talk of demolishing it. Fortunately, it was refurbished instead and is now one of the jewels in Sydney's crown. Definitely worth a look if you're visiting the Big Smoke.
