Robert Irwin has shared a sweet tribute to his sister Bindi Irwin after she revealed earlier this month that she had been forced to have surgery to remove her appendix and 14 lesions as a result of her endometriosis. Doctors also needed to repair a hernia that she acquired during childbirth four years ago.

Bindi pulled out of the Steve Irwin Gala in Las Vegas for the surgery, leaving Robert to host the event solo. It comes after the Wildlife Warrior had 37 endometriosis lesions and a cyst removed two years ago.

Taking to Instagram, Robert shared a photo of himself and Bindi wearing their khaki Australia Zoo uniforms. He wrote, “Happy to see you on the up and up, Bindi. You face every hurdle head on, take it in your stride and inspire us.”

Bindi commented on the post, “One day at a time. Tremendously grateful for your support. You’re the best.”

“We’re a good team!” their mum, Terri Irwin, also wrote.

Many of the Irwin family’s fans also commented on the post, with one user writing, “You know parents have done a good job when siblings show love for each other.”

“I just love your relationship,” another added. “I’m also really close with my sister. It’s an amazing thing, having a sibling as a BFF.”

“Bindi, as someone who is fighting endometriosis as well, thank you for being the light in the dark tunnel of madness,” a third said.

“They don’t call her a warrior for nothing,” another said.

On the same day as the Steve Irwin Gala, Bindi revealed she underwent surgery. She shared a video and a lengthy statement on Instagram, which read: “I am so thankful that I got the help I needed with Dr. Seckin and Dr. Chu at Lenox Hill Hospital. After having a grumbly appendix, I finally had to seek help the day of our Steve Irwin Gala in Las Vegas.

“I consulted with Dr. Seckin, and we agreed that if I flew to New York, he could also check for endometriosis again. Surgery was a success. My appendix was removed, along with another 14 lesions (after having 37 endometriosis lesions and a cyst removed two years ago). I also had a repair to a large hernia I acquired through childbirth four years ago.”

She continued, “Thankfully, I am on the road to recovery. I appreciate all the kind messages I’ve received, and the support for our Gala in Las Vegas. Credit to Robert for hosting the evening, he did such an incredible job raising funds and awareness for Wildlife Warriors.

“And thanks to my family for always being there for me. I have so much love for dear Chandler & sweet Grace. Thank you to Mum for being there with me every step of the way. And rest assured, I’ll see you at the next Steve Irwin Gala in Brisbane this November. One day at a time. Time to heal now. Sending my love to you all.”

Her followers shared their support, with one person writing, “To raise awareness even in these tough moments is just so incredible. Heal well Bindi! We’re all cheering you on.”

“14 lesions after only 2 years?!” another said. “And they wonder why women with endo are in such pain! Glad you are on the mend, and thank you for using your platform to highlight such a blindspot in women’s health.”

Some also shared that Bindi sharing her endometriosis diagnosis with the world is what helped them find out they also had it, with one woman writing, “Bindi, you are the reason I learned about endometriosis and was able to get diagnosed last year after years of terrible pain. You have made such a major difference in my life. Endo sucks and nobody should have to go through it, you’re such a valuable advocate for us as you share your journey with the world.”

In response, Bindi shared another post, which read: “Healing. Thank you for your incredible words of support and kindness. The reason I share my health journey is because more girls and women desperately need answers to their undiagnosed pain. I’ve battled with endometriosis for more than 12 years.

“This disease is crippling and can make you feel incredibly isolated. We need to raise awareness and change the narrative for women’s health. I see you, your pain is real, and you deserve answers and genuine health care.”
