The reason there are so many kangaroos in Australia is due to lack of natural predators. though many species of kangaroos have become extinct since Man introduced non-native predators such as cats, dogs and foxes, the larger kangaroos such as the Red and grey kangaroos have actually benefitted from European changes. In some cases, land clearing of bushland and woodlands to create pastures for cattle and sheep over the past 100 years has provided feed to kangaroo populations, which eat far less than stock animals do.

Kangaroos have no main natural predators apart from dingoes that were introduced into Australia in the last 1000 years or so. Even then, dingoes will not prey on healthy adult kangaroos - only on frail and young kangaroos. The Marsupial Lion, now long extinct, was also believed to have been a main natural predator of the Kangaroo.

With little threat from predation and thousands of square kilometres of land cleared to produce feed for domestic grazing stock, kangaroos have flourished.
