The NPL Queensland team have already become the first team from the Sunshine State to reach the last four but are keenly aware a victory over Melbourne City at Perry Park would provide a notable milestone for non A-League teams.

Since the FFA Cup started in 2014 every NPL team to reach the last four has been beaten by A-League opposition.

Strikers defender Matt Richardson said he and his teammates take on City with no fear, especially having already eliminated A-League opponents Wellington Phoenix in the round of 32.

"We're not in the top four just to make up the numbers. We want to go all the way and try and win it," Richardson told AAP.

"There's no reason why we wouldn't put our best foot forward and see what we can do.

"There's a reason we've come this far. We've already beaten A-League opposition so we can hope to do it again. It's just about on the night and see what happens."

A big personal challenge looms for 21-year-old Richardson against City as he attempts to shackle Socceroos striker Jamie Maclaren.

The ex-Brisbane Roar favourite has formed a lethal partnership with English import Craig Noone in City's run to the semis, the pair scoring all of the team's goals so far in the competition with four apiece.

"Obviously he's a centre-forward, I'm a centre-half so it'll be a one-on-one battle there but at the end of the day I can't dwell on his achievements or how good they are," Richardson said.

"I just have to play my game ... do my best to defend and do my best for the team. I'm not too worried about it."

Tuesday's game kicks off at 7.30pm AEST with the second semi-final between Central Coast Mariners and cup holders Adelaide United to be played on Wednesday.
