Tilio played a key role in City's premiership-championship double under Patrick Kisnorbo last season and scored a memorable long-range goal on his Olyroos debut in a surprise win over Argentina at the Tokyo Olympics.

The 20-year-old winger will remain with City until the end of the 2023/24 season.

"The club has shown a lot of faith in me so it was really a no-brainer to extend my contract," Tilio said.

"I want to help the club continue to have success and create more memories in my time here so I can repay the faith that they have put in me."

Tilio started 10 of City's final 11 matches last season, banking a goal and an assist in the semi-final win over Macarthur.

"My goal this year is to continue to develop as a player and person to take my game to a new level," he said.

"I want to push my teammates and push myself to play each week and show what I'm capable of by growing in confidence and bringing more to the team than I have before."

The ALM season is set to kick off on November 19, with City hosting Brisbane Roar at AAMI Park in the opener.
