On 21 May 2018, Carney officially signed with North Sydney, in reaction to the signing, General Manager of football at Souths Shane Richardson said "We've spoken to Norths about Todd Carney and it's our position that we will develop our young halves, as opposed to bringing in a player from outside the club in this instance," Richardson said. "'The 'Rabbitoh Way' is to build a culture that rewards young players for hard work, a culture that has respect for the club and its people, respects the members and sponsors that invest financially and emotionally into what we are doing here at South Sydney, and a culture of developing young players that want to play for South Sydney and that we see having a future NRL career".
