Not much. The largest open exhibit on the right was empty and is apparently an indoor area for kangaroos or wallabies, I presume when the outside weather is bad? There was a snake exhibit on the left, a tree shrew exhibit on the left and a tree kangaroo exhibit on the right. A couple others that I don't recall. Not that good of an exhibit - there seems to be no reason why most of these animals could not have been outside (especially in Brownsville).

The fact that I almost don't recall this at all tells a story - however, since I was working in Australia and visited over twenty animal collections there, no Australia-themed section in a zoo abroad has managed to captivate me.
On my visit in August 2010 there were bats, two exhibits of sugar gliders, the indoor holding area for almost 20 eastern grey kangaroos, a Virginia opossum (a marsupial but from North America!), Matschie’s tree kangaroos, tawny frogmouths and bettongs. There used to be kowaris and cuscus here as well, but they are both gone from the zoo. Outside are aviaries for salmon-crested cockatoos and kookaburras, as well as the eastern grey kangaroo outdoor yard, a cassowary/cape barren goose enclosure and a basic walk-through aviary with cockatiels and lots of doves. Mindoro and saltwater crocs are in nearby pools that are lush with vegetation.
I checked ISIS today and according to that site the roos are actually western grey kangaroos (of 3 different subspecies) and there are at least 15 of them.
