Mike Cooper is to leave St George Illawarra Dragons and rejoin Warrington Wolves from next season.
The prop, who left Warrington for the NRL in 2014, was under contract with the Dragons until the end of the 2017 campaign.
However, he has been released from that deal on compassionate grounds, allowing his family to return to the United Kingdom.
"It was a hard decision to make but both my partner and I have decided that is what is best for our young family is to return home at the end of the year," England international Cooper said
"It's not a decision that we have both taken lightly and we both spent a lot of time thinking about what was best moving forward for the three of us.
"We will have been here three seasons come the end of the year and that is a long time to be away from family and friends, especially when you have a young child."
Warrington coach Tony Smith, whose side are second in Super League, told their official website: "It's great news and a great signing for the club. It's probably something that we hoped for a few years ago, that Mike would eventually return to our club, but
it's probably a little sooner than we thought considering how well he's done.
"It's a real shot in the arm for the club and we really look forward to taking on a player who seems like a veteran here in his early years, at such a young age. It's testimony to Mike that he wants to come back home and play for his home-town club.
"He is a very proud Warrington boy and we are more than happy to embrace him and look forward to working with him again. I enjoyed my time working with him and he has come on as a player a whole lot since then as well so I think his addition will really strengthen our club."
St George are ninth in the NRL after 12 games, level on points with Canterbury Bulldogs and Gold Coast Titans in the race for the top eight.
