This is the infamous Dingo. They were brought to Australia around 4000 years ago so it's debatable if they are wildlife or an introduced pest but they have certainly filled a predatory niche. Unfortunately, like many wild animals, they have been drastically reduced in numbers and have cross-bred with domesticated dogs. On Fraser Island (just north of Brisbane) this population is about as pure blood dingo as exists on Australia today. It's a gorgeous paradise island and the dingos frequent the beautiful beaches. You may have noticed a blue tag in the left ear. A tag in the right ear means this is a female. They are known to bite people and attack kids so if one becomes a problem the park staff know which one is which.
