During the press conference on Friday, Bolt said the Mariners had not yet indicated whether he had secured a spot on the team.
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.
About 15 minutes later, Macarthur's defenders clashed with the goalkeeper, and the ball spilled loose for Bolt to walk it into the net.
"I think [Bolt] can make it".
Eight-time Olympic champion Usain Bolt is no more outrunning the fastest men in the world but the sprint great, it seems, will continue mesmerising his fans on the football turfs in Australia. "They will treat me just like a footballer should be treated".
"He covered himself in glory tonight and I think that everybody is super pleased for him. you've got to take your hat off to him".

If you thought Kanye West would have air-tight security you couldn't be further from the truth. How do we know? Kanye West is in the house - the White House, to be precise.
After catching his breath, Bolt was back in the action, beating two players after a lucky bounce before his shot was dampened by strong defending by Macarthur.
"His speed endurance is a little bit better but he still looked exhausted after 15-20 minutes".
"He is very humble", he said of Bolt.
"Slight improvement if you want to say that but his touch is still very poor", Bosnich said of Bolt's performance today.
"I'm just pushing myself and have put in the work so now I have to go out there and execute".
The A-League season begins next weekend, as Central Coast goes up against Brisbane Roar on Sunday, October 19.
The Jamaican then capitalised on a defensive mix-up to score his second just after the hour mark before being substituted with the score at 4-0.
Bolt soon will discuss his future with the Mariners, who kick off their A-League (Australian first division) regular season next week.
