Creative attacker Ono gave the league newcomers a big boost by agreeing terms for the 2013-14 season as they prepare for their Saturday home derby with Sydney FC where they can clinch the regular season title.
"I love this club and I want to play more football with them so we can achieve more beyond this season," Ono said in a club statement.
"I have told anybody who asks me about the club that it is like a big family.
"Of course I mean the players and the coaching staff but I also mean everyone who works in the club - they are like family to me."
Ono said he had unfinished business in the Hyundai A-League with the Wanderers.
"We have had a great season and there is much more to do and I want to be part of it," Ono said.
"We are all looking very forward to our clash with Sydney FC and any other challenges that come along this season.
"Once this season is over I will then look to next season and prepare with my club the best I can."
Coach Tony Popovic said Ono was an outstanding player who had fitted in very well at the club.
"We see his talent every week with his creativity and his skills," Popovic said.
"Shinji is an integral part of our team building next year and we are very happy that he has re-signed with us."
