Now the Socceroo wants the Australian Professional Leagues (APL) to come on board with his bid to give more communities the chance to connect with professional soccer and grow the A-Leagues in the process.
Mabil scored his first City goal to deliver a 2-1 win over Sydney FC last week and celebrated with fans from western Melbourne's South Sudanese community.
The 31-year-old was born in a Kenyan refugee camp to South Sudanese parents before his family settled in Adelaide.
Mabil organised 100 tickets - mostly for young fans - through the Mät Foundation, co-founded by fellow Socceroo Thomas Deng. A bus nicknamed the 'Awer Mabil' transported those spectators to and from the game.
That will be repeated for Saturday night's match against Western Sydney at AAMI Park.
"It was an unforgettable moment for the kids, and it's something that they will never forget," Mabil said.
"And for me, that's what I'm all about, to be honest, about communities.
"And I've worked very hard with City to make sure that we provide what is needed for the kids to be able to access games, and we're gonna do it this weekend."
Mabil isn't stopping there.
"It makes me happy that it's not just my community - now we're going to reach out to the other communities," Mabil said.
"Because that's what football is all about - getting the kids inspired from all different backgrounds, and that's what we're going to do this weekend, and we'll continue to do.
"I hope the league will jump on board also. So when I'm in other states - because I'm sure there's other communities in other states that we can help ... that's something I have to have a word with the league about to organise in the future."
Mabil believes it can also help the A-Leagues garner new fans.
"Football is the number one played sport at junior level," Mabil said.
"So this is the easiest way to motivate the kids and when the kids are inspired, they will talk to their parents, and then they will come to the game.
"So it can only be beneficial for the league and for the game in Australia."
Mabil hopes to put on another show on Saturday.
The attacker has re-established a tight connection with his former FC Midtjylland teammate Emiliano Marcondes.
"Marcondes is my boy," Mabil said.
"We played obviously in Denmark together and we won the league there.
"He is, for me, the best player in the league, and it's an easy connection to have with him."
