There are two main coral reefs in Australian waters. The Great Barrier Reef is the largest coral reef in the world. It extends 2300 km down the coast of Queensland, Australia. On the west coast, off Exmouth, is Ningaloo Reef, another impressive coral reef.

Two animals that I know live on the sand of a Coral Reef are a Jawfish and Garden Eel, but there is guaranteed to be many more.
Fish aren't mammals...
Colonies of coral take on many shapes and sizes. No two look the same. Some resemble plants, some resemble brains, some are spiraling while others are flat like a table top. All of these make up a coral reef. There are many different types of coral reef as well. There is atoll reef, barrier reef, fringing reef, table reef, apron reef, bank reef, patch reef and others. Each of these different types of coral reef grows in a different environment. For more information about the specific shapes associated with the reef types listed above, see the related link.
No, they are made by polyps, which confusingly are also known as coral (but coral the reef is made of and the polyps are two different things).

The Great Barrier Reef was formed over two thousand years ago by nature itself.According to the Great Barrier Reef Marine Park Authority the current, living reef structure is believed to have begun growing on an older platform of coral reef about 20,000 years ago. The older coral reef platform is believed to be 500,000 to 600, 000 yeas old.
Runoff from farms near coral reefs can cause two basic problems; sedimentation and nutrification. Sedimentation means that silt and dirt particles get washed into the ocean, blocking out light, and landing on and smothering reef animals. Nutrification causes large algal blooms that can easily overgrow and crowd out coral reef animals.
coral reefs are made in the oeacen by rocks and plants that are in the oceacen for handereds of years.
