Blakey has trained with the Roos' father-son program, last year spent time at the Lions with their Academy, and has been a part of the Swans' Academy for nearly a decade since his father John Blakey joined the club's coaching panel.
"At the moment, I still have to play a lot of good football before I think about it," he said.
"Dad has a rich history at both North and Brisbane, so I'm not just focused on Sydney. I love Sydney and Sydney's home at the moment, but obviously dad won two premierships at North and started his career with the Lions which was so good for him.
"I'll keep my options open and I'm not set on what I'm going to do."
