The eight-time Olympic gold medal victor and current record holder for the 100 metres is aiming to secure a contract with the Australian side after joining them on trial at the start of August.
The 32-year-old eight-time Olympic gold medallist is trying to transform himself from global athletics superstar to professional football player and hopes to win a contract for the Mariners ahead of the 2018-19 Australian top flight campaign.
"To score two goals, it's a good feeling, it's what I'm working towards, I try to improve myself, I try to get better and I'm doing that".
"It was my first proper game and I'm just happy I got a chance", Bolt said. "I'm keen to be a Mariner, and get into the team". Cue hysteria in Campbelltown as the trademark "Lightning Bolt" celebration was beamed around the world.
His second goal wasn't quite as impressive as his first, but that didn't stop Usain Bolt cementing his position as a pro footballer with a Fortnite dance. The retired sprinter and 100-meter world record holder not only made his very first professional soccer start, but he scored his first two goals.

He was persuaded by Treasury Secretary Steven Mnuchin that Powell, who was already a Fed governor, would be a force for stability. Moreover, Roberto Perli of Cornerstone Macro calculates that a big part of the higher rates is an increase in the "term premium".
His dart to the near post created space for McCormack, who confidently headed home his first goal in Mariners colours from fellow new signing Tommy Oar's delivery.
Bolt added his second of the evening by taking advantage of some outrageous defending before rolling the ball into an empty net.
It was the first game Bolt has started since joining the A-League club in August for an indefinite trial. The Mariners will offer Bolt a permanent deal should he impress enough during his trial.
Playing in a central striking role, he scored his first in the 55th minute to put Central Coast 3-0 up with a powerful left-footed finish after racing onto a Ross McCormack through-ball.
Since retiring in summer 2017, he has trained alongside club teams in South Africa, Jamaica and Norway, plus had a much-publicized visit with Borussia Dortmund in March.
