The experienced 48-cap Socceroo may have finally found a home back in NSW after brief stays at clubs throughout the football world
Carney, 30, joined the Jets in February and went on to make seven appearances, providing three assists as they narrowly missed out on a place in the finals.
"I've really enjoyed the vibe since I've been in Newcastle and I'm happy to have signed on for a couple more years," Carney said.
"I'm confident we can go into next season and have a good crack at it and give this town what it deserves, which is a team that not only makes the playoffs but is able to achieve even more than that."
Agreeing to remain with the Jets could afford Carney some much-needed stability after brief spells with little success at AD Alcorcon, Bunyodkor and the New York Red Bulls in recent years.
Former Adelaide United assistant Phil Stubbins has taken over from interim boss Clayton Zane as the Jets' head coach going into the 2014-15 campaign, and Carney believes the new man has what it takes to guide the team to success.
"I was really pleased when I had the chance to sit down with Phil and discuss his plans for the team," he said.
"I think with the new coach and the squad we're building, there are some really exciting times ahead for the Jets."
