Hunt has signed a one-year contract, while Rankin’s two-year deal secures him at the Club until the end of the 2017 season.
Hunt debuted for South Sydney in 2012 and has played a total of 21 NRL games across three clubs, including Parramatta and most recently St George Illawarra.
The 26-year-old played seven NRL games for the Dragons this year and can cover wing or fullback.
The 23-year-old can play a range of positions including fullback, five-eighth and halfback.
Head Coach Jason Taylor said both Rankin and Hunt will bolster the Club’s depth next year.
