Yeah I went a couple weeks back and it was quite disappointing to see how there was mostly double ups or empty enclosures out there compared to when I was younger 10ish years ago maybe where each enclosure had something different in it.
I'd love to see a lot more of the enclosures in the Treetop trail inhibited instead of remaining empty. There's currently three empty enclosures out of all eight, and Melbourne could easily find species to move there. Squirrel Monkeys are extremely active, and could suit one of the larger enclosures. Golden Lion Tamirans would also fit the final enclosure, and I'd like to see Binturong return to Melbourne. Melbourne even have a Tree Kangaroo off display that could be displayed in one of the enclosures
