Bindi Irwin says she sees 'so much of dad' Steve in brother Robert as he turns 19

It is very common for children to grow up to be versions of their parents. Bindi Irwin also believes her brother is much like their late father, Steve Irwin. The 24-year-old's younger brother, Robert Irwin, is turning 19 on December 1 and has already received several blessings and wishes from all over the world. Bindi posted a beautiful message celebrating her brother's birthday on Instagram, writing: "Happy Birthday to the taller Irwin sibling and greatest brother in the world." She also shared a photo of herself with Robert standing under a sign that reads "Watch your head."

In her post, Bindi went on to describe her brother as somebody who "lights up our life with your hilarious sense of humor and kind heart." She added: "I see so much of Dad in everything you do and I know he would be beyond proud of you. We all are." She thanked the teen for being the best uncle to her daughter Grace and a "fantastic brother to me and Chandler." Several Instagram users wished Robert in the comments with one writing, "Happy Birthday to a fine young man and a credit to his father's legacy." 

Chandler Powell, Bindi's husband, also shared a photo of him and Robert laughing while assisting little Grace on a surfboard. He wrote in the caption: "Happy Birthday to my brother-in-law and Grace's Funcle, @robertirwinphotography. You make the most of every day and find the fun in everything we do! Thank you for the one million laughs over the years." He added, "I feel lucky to call you my brother and friend. Here's to more awesome adventures and epic waves caught together in the many years to come."

Robert and Irwin are the children of the famous Australian zookeeper and conservationist, Steve Irwin. He was a celebrated wildlife expert who tragically died after a stingray barb pierced his chest while he was diving at the age of 44 in 2006.

Robert's birthday falls only a few days after the Steve Irwin Gala Dinner, an event honoring the legendary "Crocodile Hunter," which took place on Saturday, November 26, in Brisbane, Australia. The teen has been following in his dad's footsteps to become a great zookeeper and conservationist. Robert is also a wildlife photographer and attempts to honor his dad's legacy with everything he does. 

Sharing a throwback photo of him and his late father holding a little crocodile a few weeks ago in honor of "Steve Irwin Day" on November 15, Robert wrote in the caption: "It's a day to remember everything Dad was about — conservation, dedication, fun and family. It never ceases to amaze me what an impact Dad had on the world when I see people in every corner of the globe celebrating his life and legacy on this special day."

Robert works with his family at the Australia Zoo to rescue and research animals. Moreover, he recently released his photography book "Robert's Irwin Australia!" which features "powerful imagery from the most rugged, beautiful, surprising and awe-inspiring continent on Earth."
