“I’m going to get away from reality for a bit and then I’ll come home and face the music.

“It was hard (to say bye to Berina and Ayla) but I’m only going for a week. Having MND can be a bit confronting for her, but she understands and I’ll be home soon.

“I want to help find a cure and inspire people.

“I’m going over there to get ready to fight for my life.”

According to Code Sports, Arrow will be working with doctors and health experts.

It comes one day after the Queensland State of Origin enforcer and Colakovic spoke publicly about their situation.

Arrow left everyone in tears as he heartbreakingly shared his wish to see his daughter grow up in a raw radio interview on Friday.

Berina said during the interview with KIIS FM she hopes to give Ayla a brother or sister.

“I think in the lead-up to the diagnosis, I was in a bit of denial,’’ Berina said.

“It kind of spiralled into him losing a bit of his voice and that being very visible.

“He’s 30. We have a little one at home, she’s just turned one, so for me it was very, very hard.

“I would love Ayla to have a brother or sister, but even with stuff like that, those are big discussions, given the disease and lifespan of the disease and stuff.

“Those are probably big personal milestones, but I’m happy to go wherever he wants to go.’’

Arrow’s comments then provoked an emotional response from the hosts, with Georgie Tunny breaking down in tears.

“For me, it’s (to) be around my for my daughter and Berina for as long as I can,” Arrow said.

“And she knows I would do that. I’ll fight and I’ll be there. I will.”

Arrow and Berina, who got engaged in October 2024, said they have deliberately avoided receiving a prognosis.

The average life expectancy is 2-3 years from diagnosis, according to MND Australia, but the disease and its progression varies largely.

In an exclusive interview with news.com.au’s Extended Bench, neuroscientist Dr Alan Pearce said sadly there is currently not a lot that can be done to treat the disease, and the fact that he is an athlete would have no bearing on how fast or slow his decline is.

“It’s a very progressive disease and one that is difficult to try and treat,” Dr Pearce told news.com.au’s Extended Bench.

“You can manage the signs and symptoms but essentially, there are no treatments.

“Unfortunately, it won’t have much bearing (that he is an athlete).”

Arrow is not giving up, vowing to battle with all he has for his family.

“(The prognosis) for me, it’s be around for my daughter and Berina for as long as I can,” he said.

“And she knows I’ll do that. I’ll fight, and I’ll beat it — I will.”

Arrow isn’t fighting alone with the sporting world and Australia rallying around the former Rabbitohs star.

“This is such an important & brave discussion to have, from both perspectives. sending so much love & strength,” one wrote in response to Arrow’s interview on KISS shared online.

“Australia is with you,” another said.

“Jai your strength is an inspiration to so many . Your bunnies family , and wider NRL community are deeply motivated to stand with you and your family through it all. You sir, are a true gentleman,” a third commented.

While a fourth said: “Australia is backing you every second Jai.”
