The Outback is full of wildlife adapted to the tough conditions. In Kakadu, in the tropical north, the crocodile population is expanding. Taking a boat trip on one of the many rivers, it will not be long before you spot these pre-historic reptiles lounging on the banks or cruising the warm waters. Noisy galahs and black cockatoos fly through the eucalyptus trees, and long-legged jabiru storks wade in the wetlands. In the drier regions, red and grey kangaroos bound easily across the landscape – these symbols of Australia will provide a lasting memory of an amazing journey.
