NO.1: Kangaroo Island Among the many attractions in South Australia, my favorite is Kangaroo Island. Located in South Australia, Kangaroo Island is close to Adelaide and is Australia's third largest island. From Adelaide, take the ferry and arrive in 45 minutes. It is rumored that when the island was first discovered, there was no human habitation. Only the kangaroo was squatting, so it was named Kangaroo Island. To this day, the population of Kangaroo Island is still less than 4,000, but there are tens of thousands of koalas. So here is also affectionately called: the zoo without fences. NO.2
