Melbourne Storm centre Ryan Morgan is to join St Helens from the 2017 Super League season.
The 26-year-old, who started his career with the Parramatta Eels, has signed a three-year contract at Langtree Park.
"I'm really looking forward to coming over to St Helens. It has a great history and is a successful club and that is what excited me about the move," he told the club's official website.
"It was a tough decision to make, especially moving away from my family, but being part of a successful organisation and trying to build something in England made the choice easier.
"I spoke to a couple of former Super League players before deciding and they had nothing but good things to say about the club and the comp.
"Blake Green is here at Melbourne and he said he enjoyed the lifestyle and the footy - as did Willie Tonga too.
"Hearing that made the decision a lot easier."
