Despite the unusual circumstances, Hannebery said he and Sydney agreed on him trying to move back to his native Victoria.
Hannebery added he would be happy to stay with the Swans, but is confident about a deal being struck.
"It all happened very quickly as I thought I'd be a Swan for life," he said.
"Things change really quick. 'Why now?' is because I guess it's probably the right time."
Injury restricted Hannebery to 15 games this season, his lowest total in nine years.
But he played the last four matches and is upbeat about what he can offer St Kilda.
"I have a lot of work to do, but I'm really confident I can get back to full health and top form," he said.
