Hill is locked up with the Wire until the end of the 2019 season and was recently made captain of the club.
Hill said if the right opportunity came up in the NRL he would be interested.
“I’d never say never,” he admitted.
“Maybe I’d had the opportunity before I signed again. I’ve got another three years after this year.
“My wife had fallen pregnant again so we just didn’t think it was the right time. But I’ve got ambitions. If the times right for me to go I’d have no… but if I didn’t go it’s not something that’s major to me.
“A lot of the lads love it. I speak to ‘Jammer’ and he loves it over there. So if it came around I wouldn’t mind having a shot.”
Hill described being made captain of Warrington as a massive honour and a real privilege.
“Especially some of the captains that have been here, like ‘Moz’,” he said.
“I learned a lot off him when I first got here and I think he was one of the first people to text me when it came out, congratulating me.
“So it’s a real honour and a massive privilege not only for me but for my family as well.”
Warrington are bidding to reclaim a top four spot this season after a difficult 2015 campaign. The Wolves have strengthened considerably with signings from rival Super League clubs and from Australia.
“I don’t think we fell short [at the end of the year], we fell short all year,” Hill said.
“We were never at the races. I just think we didn’t click. Maybe we needed a bit of luck in there and we didn’t get in.
“But that’s life when you have a couple of injuries. Again that’s life, we have to deal with it.
“We’ve got a lot more strength in depth now and quality as well so. We’ve bought really well. I’m really excited about this year.”
