Carney has an option in his favour for the 2011-12 seasons, the clause offering him an out after the 2010 season as uncertainty continues over coach Neil Henry’s future with the club.
Henry is contracted through to the end of 2009 but has been strongly linked with the Brisbane job which becomes vacant at the end of this season.
Carney says he rejected offers from other clubs because Canberra felt like home and he says he has a premiership and State of Origin jumper in his sights.
“At the end of the day my heart was here,” Carney said.
“Money doesn’t buy happiness and I feel I’ve got my happiness here.”
