Terri Irwin and Robert Irwin have shared an update on Bindi Irwin’s ongoing struggle with endometriosis.

While attending the third annual Steve Irwin Gala in Las Vegas on Saturday, May 2, the mother-son duo touched on 27-year-old Bindi’s absence at the event as they also opened up about her health.

“Bindi is doing so much better now,” Terri, 61, told E! News in a joint interview with Robert, 22. “So, things like a lot of travel are a bit challenging for her at the moment and so she’ll be here next year to celebrate this wonderful night.”

“This year she’s just staying a little close to home. So, ironically, it’s less taxing for her to be home feeding crocodiles,” she continued of her daughter, whom she shared with late husband Steve Irwin.

“She’s with us in spirit, for sure,” added Robert,

The annual gala is hosted by Terri, Robert and Bindi to fund and continue the conservation work Steve was so passionate about.

The family works as conservationists at the Australia Zoo in Queensland, ensuring that Steve’s legacy “lives on” and continuing his mission of “Conservation Through Exciting Education,” per the zoo’s website.

“Australia Zoo, there’s 500 in our team,” Robert told E! News. “500,000 acres of conservation land that we have. Someone has got to hold down the fort, so Bindi’s doing a great job of that,” added Robert of his elder sister’s absence.

The update on Bindi’s health comes after she revealed in March that she had had 50 lesions, caused by endometriosis, “cut out of my body” in the past three years.

Describing her experience as she marked Endometriosis Awareness Month, Bindi called living with the chronic condition “indescribable, inescapable pain.”

“As this month comes to a close, I urge everyone to remember this invisible disease each and every day,” Bindi captioned a March 30 Instagram post alongside photos of herself in the hospital.

Along with the lesions, the mom of one also said a “chocolate cyst that was adhering my ovary to my side was removed” and she’d undergone “an appendectomy and a hernia repair.”

“Trying to keep my invisible illness to myself after being told by doctors it was just ‘part of being a woman.’ I spent 10 years being undiagnosed,” she continued, adding that she felt “weak and deeply insecure” as a teen and young woman.

“I was trapped in my own body,” she wrote.

According to the Mayo Clinic, endometriosis is an “often-painful condition in which tissue that is similar to the inner lining of the uterus grows outside the uterus.”

One of the more painful symptoms of the condition is a “chocolate cyst,” which the Cleveland Clinic says resembles “brown, chocolate-like fluid” and is filled with old blood.

Bindi was diagnosed with endometriosis soon after welcoming her 5-year-old daughter, Grace, whom she shares with husband Chandler Powell.

In August 2023, Bindi told PEOPLE that getting the right treatment for the condition has been key “Now I wake up in the morning, and I don’t have to take anti-nausea medicine or have my heat pack. Being able to go for a walk with my daughter and not feeling like I have to throw up in the bushes is just wild to me,” she said.

“I was tested for everything. Every tropical disease, Lyme disease, cancer, you name it,” Bindi added. “I had every blood test and scan imaginable.”
