Star Wallabies lock Adam Coleman is content with the "fine line" players must tow when tackling decoy ball carriers, after the TMO reversed an Israel Folau try for a hit Coleman laid on James Ryan.
Coleman was one of the Wallabies' best in the 18-9 win, setting the tone with some shuddering hits in the first 20 minutes and following suit with 14 total tackles - the large majority of those dominant in contact.
A farcical second half intervention from TMO Ben Skeen stole some of the limelight from his stellar performance, though, Coleman penalised for an off ball hit on James Ryan long before Israel Folau crossed for the Wallabies' second try.
"It was a fine line there. It went across the face and I finished the tackle," Coleman said.
"Unfortunately it got pulled back and that’s the refs call. It was a fine line there and I probably overstepped the mark there a bit."That’’s part of my game, being physical and that’s something I really wanted to step up this week was my line speed.
"We could have easily gone into our shells there and then gone away from our processes but we really stuck to our processes and then we got an outcome after that."
While Ireland didn't respond with too many huge hits of their own, Coleman is expecting the Irish pack to kick things up a notch once more in Melbourne.
"It was a battle of attrition out there," Coleman said.
"Both teams were very physical and it’s something we expected from Ireland.
"We know Ireland are going to be a different team next week.
"We need to review that game hard and then really focus on next week.
"Yes, we got the win here, but there’s two more games to go - we look forward to recovering now."
One area of the Wallabies' game which will no doubt be reviewed is the lineout - Brandon Paenga-Amosa missing three throws in his Test debut.
There looked to be a communication issue in at least two of those lineouts but Coleman said they were little more than teething problems which will be rectified in the coming days.
"It was a six-day turnaround, there was always going to be some teething problems," he said.
"But we’ll look to rectify that next week.
"Really happy for Brandon making his debut - he’s made a lot of sacrifices and (I'm) very proud."
