The given pictures illustrate the development of a zoo in Australia from 1960 to the present.
Overall, the area has involved several significant changes, most notably the relocation of some amenities and the addition of new facilities.
Starting with the northern section, the northwest harbor was moved to the top left corner to accommodate the construction of a new entrance. Additionally, a new ferry terminal was built at the end of the path leading to the sea, allowing more tourists to visit the zoo. As visitors walk down the path from the ferry, they will notice that the bird and seal show sections, previously located at the first right turn, was removed to make way for a cable car that extends southward through the zoo. The former seal show area was replaced the chimpanzees, which had previously been located at the second right turn. Subsequently, the African animals section in the northwest was relocated to the flank of the new seal show area on the left. Meanwhile the Australian animals zone remained unchanged over the whole period.
Turning next to the southern area, in the other side of the path, opposite to the ferry, there was another entrance was constructed. The gift shop, which located to right of the former entrance has been developed into a larger building. Contrary, in the eastern part the picnic area remains the same over the time frame.
