It could be expanded into the bongo enclosure and the little-used portion of the lawn area behind the reptile house. The bongo could be moved out to Werribee (they're in a terribly boring, bargain basement paddock) and some eland and even a rhinoceros or two brought to Melbourne. Admittedly, it essentially re-creates on a smaller scale the Floodplain paddock at Werribee, but that could be turned into a positive - use it to promote Werribee somehow.
