Bindi Irwin penned a touching tribute to her late father Steve Irwin on Instagram over the weekend, remembering him as "The Greatest Dad on Earth" on Sunday, Nov. 15, which is recognized as Steve Irwin Day in the wildlife expert's native Australia.
Steve Irwin was killed by a stingray on Sept. 4, 2006, as he was filming underwater footage for a documentary.
