King has also played ten Tests for Australia, nine State of Origin matches for NSW and two games for Country Origin, as well as being selected in the inaugural ESL Exiles team which defeated England earlier this year.
Standing 190cm and weighing in at 100kg, King is one of the leading players in the English Super League competition today, and will return home to Australia over the next two years.
Rabbitohs CEO Shane Richardson is pleased to be bringing an experienced outside back to the Club.
“We’re really happy to be able to attract a player with the experience and talent that Matt King possesses to our Club for the next two years,” Mr Richardson said.
“Matt was one of the leading lights during Melbourne’s dominance of the competition, alongside players such as Greg Inglis and Michael Crocker, and also our new Head Coach in Michael Maguire.
“He has the runs on the board and we’re looking forward to welcoming Matt and his young family to South Sydney next season.”
