The Red Dragons wrapped up their time in Australia and New Zealand by losing 1-0 to the A-League side at the Sky Stadium. Luke Flowerdew's 49th-minute close-range goal made the difference as the Welsh club finished its tour with two defeats from three friendly games Down Under.
Wrexham goalkeeper Okonkwo had a night to forget as his costly error gifted Flowerdew the opportunity to score the winner. Okonkwo should have comfortably collected a low cross inside the six-yard box but the ex-Arsenal man fumbled it and the ball fell kindly for the Phoenix star, who casually pushed it into the net.
The Championship side had quite a few opportunities to come back or seal a win. Elliot Lee had an opportunity to equalise almost immediately but his brilliant header cannoned back off the woodwork. Then, just past the hour mark, Lee attempted a powerful half-volley but goalkeeper Josh Oluwayemi pulled off a fine save to stop him from restoring parity.
Ollie Palmer also saw a goal ruled for handball as Phil Parkinson's men suffered a frustrating and avoidable loss as they prepare for the long trip back to the UK.
