There is no such species as the "grey koala".
Koalas have virtually no defence against large predators such as dingoes or domestic dogs. Their sharp claws are sufficient defence against smaller predators such as quolls and feral cats. They also use their sharp claws to climb tall, straight gum trees quickly to get away from ground-dwelling predators.

protection
Koalas have sharp claws, which are basically their only defence. When in the safety of their trees, their only predators are pythons and birds of prey, and they have no defence against these creatures.
Each of Australia's state governments enacted laws to protect the koala from around the late 1930s.
