    Fraser Island is in Queensland, Australia, about 200 kilometers north of Brisbane. It is about 120 kilometres long and 240 kilometers wide. It is a very important is land because it is completely made of sand, but there is a long beach along the east coast. Planes arrive and leave from here.

The sand makes unusual shapes. There are hills made of sand called sandblows. Nothing grows on them. They move one or two meters a year from the northwest towards the southeast of the island, getting bigger and bigger. At other places on the island, such as Rainbow Gorge, The Cathedral and Red Canyon, the sandy rocks have different colors. Sometimes the rocks are so brown that they turn the sea brown, like coffee.

Surprisingly, the sandy island has a lot of different plants and animals. There are dark forests- eucalyptus woods, beautiful flowers and over a hundred lakes. There are many kinds of birds, like owls and curlews. There are many animals there, too, such as crocodiles, flying foxes and wild dogs called dingoes.

About 500,00 people visit the island every year to see the island's beauty and nature. People enjoy camping and hiking there. Unluckily, the visitors create problems. They damage (毁坏) plants and frighten (惊吓) animals. Their sun cream (防晒霜) makes the water dirty. So it is necessary to manage the visitors. For example, people may not use motor boats or go fishing in the lakes, and they need official papers to drive there.
