true that was a very good game from the Wallabies, but Ireland weren't nearly the team they were that day and then later against the AB. They played hard but totally lacked precision. In fact that game was a big wakeup call for Ireland, I genuinely believe they were so disappointed by that performance not scoring a single try and conceding many (four ?) was just such a disillusion to them and they expected so much more and knew they were much better, that provoked a huge reaction within them all and they just tore shiit up in the next test, and possibly (I dunno) that's what gave them so much motivation and confidence entering the 6N, and winning it.
If I were Australian, I'd say maybe the second test against the Lions (although that brings that whole series to mind and isn't a fond memory...).
I may also have picked Test 3 against France, because although the opposition was woeful, it was after a huge blowout in Test 1, a crazy low-score Test 2 somewhat competitive, and then just when you thought the French had figured Aus out they take another pounding. Possibly satisfying for Aussies, although not all that much when you understand just how France were on that tour for a number of distinct reasons.
I think the best is to come, though, for Australia.
And if I'm Irish, I'd say the game against Wales 2014. Cardiff 2013 was a huge ego-boost too, but it didn't end satisfyingly, and was just a one-off. Tournament was a total failure overall. But Wales 2014 in Dublin was complete domination, the whole 80minutes, and THE symbol of Ireland's ***le.
