Carney, who spent the 2016 Super League campaign with Catalans Dragons, is trying to agree an exit from Cronulla in the coming weeks.
The 30-year-old is hoping to have finalised his future before the New Year, but the Aussie has now admitted he has options in both the NRL and Super League.
He admits his first choice would be to stay in the NRL but the former Sydney Roosters star admits a return to England is an option.
"I’d love to be in the NRL, but if it [playing again] means I go back to England I’m still in contact with a couple of clubs there," Carney told Rugby League Week.
"Everyone’s hopeful and I’ve had a lot of support, but it’s up to the bosses who run the [NRL] game.
"But until this Sharks stuff is over, which will hopefully be soon so we can move on, until that’s finished I’m still in the unknown.
"I just need to focus on this and after the fight I’ll go back home and spend some time with mum and my sisters over Christmas and then I’ll make a decision and I’ll see what I have to do to hopefully be playing here in Australia or over in England."
