The 32-year-old Olympic sprint king said at an event in his native Jamaica he planned to concentrate on a career in business.
"I don't want to say it wasn't dealt with properly, but I think we went about it, not the way we should and you learn your lesson, you live and you learn," he said, according to Television Jamaica.
"It was a good experience. I really enjoyed just being in a team and it was must different from track and field and it was fun while it lasted," he said.
"The sports life is over, so I'm now moving into different businesses, I have a lot of things in the pipeline, so as I say, I'm just dabbling in everything and trying to be a business man now," said Bolt, who scored two goals for the Mariners but failed to break into their team in Australia's A League.
The Mariners are currently bottom of the table with only six points from 14 games.
In October a Maltese club, Valletta FC, reportedly offered Bolt a two-year contract to join them but he apparently turned it down.
