Wanderers had previously lost the first-leg of their FAI Premier Division promotion/relegation playoff tie 2-0 in Fingal before the return match in Bray.

With the scores poised at 1-1 with Bray behind on aggregate going into injury-time, Brisbane-born O'Connor moved forward before heading in Gary McCabe's 91st minute corner.

The goal seemed to offer Bray a late lifeline before O'Connor went from hero to villain straight from the kick-off when he was dispossessed trying to get the ball moving and allowed Fingal to grab the sealer.

The result means 24-year-old O'Connor, who narrowly missed selection to be part of the Olyroos squad at Beijing in 2008, drops to Ireland's Division One with Bray.

O'Connor, who joined Bray as a teenager from Queensland club Rochedale Rovers, had helped Wanderers gain promotion in 2004 before their five-year reign in the top flight came to an end this week.

Other Aussie keepers who have scored include Mark Bosnich, Michael Petkovic and Adam Federici.
