Kangaroo Island is a must-see for South Australia, because the natural scenery and wildlife have enough charm to attract you again and again. One-quarter of the area on Kangaroo Island is designated as a national park and protection. Districts, there are kangaroos, koalas, lynxes, acupuncture, platypus, sea lions and other rare animals and more than 200 birds, often seeing them appear around you. The koala on Kangaroo Island is a latecomer. It has also caused ecological imbalances due to the number of koalas. The government has also taken hunts and sterilizations to koalas.
