Josh van der Flier
The Leinster youngster continues to pass every test with flying colours and is rapidly developing into a world-class flanker.
Outstanding off the bench in both games against New Zealand, he continued that form from the start against Australia.
Van der Flier made 12 tackles but it was his work at the breakdown that was most impressive. The problem Schmidt has is how to fit him into an ultra-competitive back-row.
Ireland's backline had a totally unfamiliar look to it but once again, Ringrose stepped up to the mark in another brilliant performance that proved that he belongs on this stage.
Only CJ Stander made more carries than him, and although he is destined to end up at outside-centre, he gave an exhibition of how a 12 should play. Mature beyond his years.
10 The difference in the number of penalties conceded by the two teams. Ireland (3), Australia (13).
"We have been told that. We can't talk about that in public, because they don't want the interpretations being done in public. That's the edict they have given us: we can't say anything about it; we'd love to but we are not allowed to."
A fuming Michael Cheika keeps his counsel on Jerome Garces' performance.
