About seven percent of the world's species live in Australia, making it home to the most diverse selection of animals on the planet.

Most of those animals are unique, in that they live only in the island continent.

Researchers, however, say that 20 percent of the country's surviving mammals are threatened with extinction, along with 12 percent of its birds.

The threat to the country's wildlife has prompted one organisation to restore a large tract of farmland near Canberra back to its original state, before the arrival of European settlers in the 18th century.
