He added that the 31-year-old would be required to trial and that Football Federation Australia (FFA) should support his salary.
"While Usain Bolt is one of the most famous athletes on the planet, he's not a professional footballer".
The A-League's 2018/19 season begins in October. But the big question is can he play?
While signings like Bolt might spur an initial curiosity, surely ploughing millions of dollars into turning the A-League into an novelty circus sideshow isn't the most sensible long-term plan.
"We've been working for about four or five months on this and every day it got a little bit closer", said Mielekamp. We're not asking them to fund a trial.
Usain Bolt is considering an offer from Australian A-League side Central Coast Mariners.
"Once the FFA comes back and says that they'll be part of the process, we're going to the trial", he said.

The Central Coast Mariners chief executive Shaun Mielekamp revealed that the club has spent months chasing Bolt (good luck catching him), and that a season long loan deal could be wrapped up soon.
Rallis told Channel Nine Bolt was serious about becoming a soccer player. If all does go through (which appears likely) you might need to venture beyond your local listings if you're interested in watching Bolt play.
He has since trialled with German giants Borussia Dortmund and Stromsgodset in Norway. "Maybe a club will see something and decide to give me a chance", Bolt said at the time.
According to the Sydney Morning Herald's Rachel Clun, Usain Bolt is in discussions for a trial with the Australian A-League's Central Coast Mariners.
"He has a very good left foot, and time will tell at what level he is at and if it fits the A-League... it would only be big if he could play and go really well", he said.
Bolt has confessed his love for Manchester United and has even been invited to the club's Carrington training complex in the past, while former assistant manager, Mike Phelan, is now the Mariners' sporting director.
