The two maps illustrate the main changes made to an Australian zoo between 1960 and the present day.
Overall, the zoo has been significantly transformed, with several new facilities introduced, some areas removed, and many zones relocated. The site has become more structured, with clearer access points and reorganised animal enclosures.
In 1960, the harbour was located in the northeast corner, with a single entrance in the south. A north-south road divided the zoo into two sections. To the west of this road were the African animals in the north and the Australian animals directly below. On the opposite side, the chimpanzees were positioned centrally, surrounded by birds to the north, a seal show further northeast, a picnic area in the southeast, and a gift shop in the southwest.
Today, the overall layout has changed considerably. The harbour remains along the northern edge, but a ferry terminal and a new entrance have been added on this side, while the original southern entrance has been retained. The seal show has been relocated to the former chimpanzee area, and African animals are now placed to the west of this feature. The birds and chimpanzees have been removed and replaced by a new wild animals section in the northwest, while the Australian animals remain in the southwest. The gift shop has been expanded, and a cable car has been constructed linking the seal show and the picnic area.
In summary, the zoo has experienced extensive redevelopment, with modern facilities added and animal zones rearranged to create a more organised layout.
