The Wallabies' grand slam rugby dream is over after a heartbreaking last-minute try to captain Brian O'Driscoll secured Ireland a dramatic 20-all draw in Dublin.
Celebrating his 100th Test in spectacular style, O'Driscoll sliced through a huge gap in the Australian midfield to score under the posts.
Referee Jonathan Kaplan blew fulltime immediately after Ireland five-eighth Ronan O'Gara drilled the conversion to shatter the Wallabies's hopes of emulating Australia's legendary 1984 tourists who completed the grand slam sweep over England, Ireland, Scotland and Wales.
After a dream start, with winger Drew Mitchell scoring in the third minute, the Wallabies were never headed and looked like storming Croke Park when inspirational captain Rocky Elsom crashed over in the left-hand corner to break a 13-13 deadlock 18 minutes from time.
The draw, which came on the first anniversary of Ireland's most recent defeat, snapped the Six Nations champions's eight-Test winning streak -- but would have nevertheless left the Wallabies devastated.
They will head to Edinburgh tomorrow gutted at watching their shot at history slip away so cruelly.
