Fast bowlers Charlie Stobo and Henry Thornton are the new additions to the New South Wales contract list for 2017-18, while Ben Rohrer and Josh Lalor have not been offered deals and wicketkeeper-batsman Ryan Carters has retired.
Rohrer, a veteran batsman who has played 55 first-class games during a decade of service with the Blues, has taken up a position as Tasmania's new state talent manager, though he is expected to play for the Sydney Thunder this summer.
Stobo burst on to the state scene last season with seven wickets on his first-class debut against South Australia, but injuries prevented him from adding any further matches in the second half of the summer.
"Charlie Stobo has been very impressive in grade cricket and we identified him quite early as someone of huge interest for us," New South Wales coach Trent Johnston said. "His line and length bowling is very good. He's a huge talent."
The state's new rookies are legspinner Dan Fallins and batsmen Param Uppal and Jordan Gauci. Gone from last year's rookie group are offspinner Chris Green, allrounder Jonte Pattison, and Thornton, who has been upgraded to a full contract.
