Robert Irwin – $4 Million

Just like his sister, Bindi, Robert Irwin is working hard to keep the memory of his father, Steve Irwin, the Crocodile Hunter, alive. In addition to currently starring on the Animal Planet show Crickey! It’s the Irwins, Robert has found real success as an author. The 17-year-old helped create and co-author the books series Robert Irwin: Dinosaur Hunter, a children’s series.

While not making millions as a television star and author, Robert has also become the leading photography contributor to the Australia Zoo Crikey magazine. All in all, he’s managed to put just over $4 million in his bank – not too shabby!
