There are certainly no hornbills, kiwis or birds of paradise (that I recall). An excerpt from my 2010 review:
Indo-Australia – This area has large but basic primate islands for orangutans and white-handed gibbons, an Aussie building with 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.
It is entirely possible that many of these birds were there when the zoo opened in the 70's. As seen by many of the zoo's graphics they have not been updated in some cases since that time.
