There are literally thousands of kilometres of safe , sandy beaches for children to explore ; deep dark caves where they ' ll learn about huge , prehistoric marsupials ; the murray river where they can fish and water ski ; and national parks and wide open aces where they can make noise and have fun without disturbing a horde of other tourists 据说这里有几千公里安全的沙滩供孩子们去探索:在漆黑的洞穴里了解史前的有袋动物;在墨累河里掉鱼滑水;尽情地在国家公园和空旷开放地制造“噪音” ,玩耍,而不去打扰别的旅游者。
