Kangaroo Island, the outlying island of South Australia, had no residents on the island when it was found, only kangaroos; today there are only 4,000 residents, but there are tens of thousands of koalas, known as the unfenced zoo. The entire Kangaroo Island is the size of eight Singaporeans. It takes about four hours to get around the island. If you drive by car, you can take the car to the island. Seal bay can be in close contact with seals, and the weathering of magical rocks is also very distinctive. If you are interested in the stars, then it is best. There is almost no light pollution on the night of Kangaroo Island. It is obvious that the Big Magellanic Cloud and Southern Cross are a good place to watch the stars.
