Redlands United have pulled off an incredible Westfield FFA Cup upset in coming from behind to beat Hyundai A-League champions Adelaide United 2-1 at a frenzied Perry Park on Wednesday night.

Trailing 1-0 until deep into added time, the Queensland side equalised right at the death through Michael Lee before Paul O’Brien sparked wild celebrations with an ice-cool extra-time winner.

The victory, broadcast live on Fox Sports, is just the third time a Member Federation club has beaten Hyundai A-League opposition in what is the competition’s third year.

Speaking after the match to Fox Sports, Redlands boss Matt Chandler described it as a “fantastic night” to be involved with the 98-year-old club.

While one fairytale continues, another has come to an end after fellow Queensland team Surfers Paradise Apollo fell to a narrow 1-0 defeat away to Canberra Olympic.

The Gold Coast side, in their maiden appearance on the national stage, pushed the hosts all the way but were unable to produce an equaliser.

Thanks to all the supporters following the match tonight and to @COFC1956 and @SURFERSAPOLLO for providing a great contest #FFACup #COLvSPA

Canberra forward Philipe Bernabo-Madrid latched on to hopeful long ball forward to put his side ahead in the 36th minute.

Surfers Paradise produced several openings after the restart but spurned their best chance when Burcin Yorulmaz turned a smart cross around the post with 20 minutes remaining.

Goalkeeper Faider Royer-Mejia starred for the visitors as they bow out at the Round of 32 with their pride well and truly intact.
