Sydney may be a difficult destination for Matt Dufty, with most clubs already stocked at fullback.
Penrith have Dylan Edwards and Jaxen Edgar; Parramatta have Isaiah Iongi and Joash Papali'i; Wests Tigers have Jahream Bula, Sunia Turuva and Jake Averillo.
Canterbury's options are Connor Tracey, Jacob Kiraz and Connor Votano, while Manly have Tom Trbojevic, Tolu Koula and Lehi Hopoate.
St George Illawarra have Scott Drinkwater and Clint Gutherson; Cronulla have Will Kennedy and Liam Ison.
The Roosters have James Tedesco, Cody Ramsey and Rex Bassingthwaighte; Souths have Jye Gray and Latrell Mitchell.
Dufty, 30, started at fullback in an elimination final this season and was one of its feel-good stories, but is now officially unemployed.
Souths offered the former Dragons No.1 a lifeline after he returned from Super League after Christmas for family reasons.
On a full-time training wage of $1,200 a week, plus $3,000 in match payments, he played 15 games and kept regular fullback Jye Gray out of the starting side.
He helped the Rabbitohs reach the play-offs, where they lost in week one to eventual grand finalists Newcastle.
Souths hope to find salary-cap room to keep him, but Dufty is open to another NRL club, preferably in Sydney to support his family.
