What is the predator of the Rockhopper penguin?

The fox will raid dens and eat young.

In southern Australia, where the Little Penguin colonies are, dogs (both domestic and wild) and feral cats are a major threat to the nesting penguins. Dogs have been known to get into the protective enclosures and kill off large numbers of these penguins indiscriminately.

Out at sea, predatory skuas have been known to attack penguins, while sea eagles also prey on them. Leopard seals, sea lions, walruses and orcas are also enemies of penguins.
