But Waugh said the Wallabies would be seeking clarity and explanations from World Rugby and referees boss Joel Jutge, who was also at the MCG, through regular channels.

“Joe’s comments at the press conference were 100 per cent aligned with mine as a CEO and a former Wallaby,” Waugh said.

“You’ve got to obviously give credit where it’s due in terms of the way the Lions fought back into the game and were able to seal victory, but our position on that particular decision is consistent to what Joe outlined in his analysis of that last breakdown.

“Clearly there’ll be the usual process, which is what happens after every Test match, and we’ll certainly be looking for a level of accountability from World Rugby over the next period of time.

“The game has come a long way [on player welfare] and it will continue to be one of the biggest focuses, so consistency around player welfare is critically important.

“We’ll go through the official channels for post-Test match reviews, and will expect a high level of accountability around some of the decisions.”

World Rugby declined to comment about Piardi’s decision and refereeing performance, or whether Schmidt may face sanction.

Questions have been asked about why World Rugby appointed Piardi for such a huge match, with the Italian having only handled 11 Tests before the MCG clash.

Senior World Rugby officials had sympathy for the frustrations of Australia after the game at the MCG, according to sources with knowledge of the matter who are not authorised to comment publicly.

Waugh declined on Sunday to share what communication between RA and World Rugby had occurred. He said his pride about the Wallabies’ performance in the narrow loss extended to the way the team handled the disappointment post-game.

“All contacts we have between Rugby Australia and World Rugby should stay between those two parties,” Waugh said.

“We obviously respect the governing body, and the way we should behave and integrity is one of our key elements of what we’ve been trying to drive and instil in the organisation, and how we behave on and off the field is very important to us.

“You saw the class the players showed in clearly a very high-pressure situation and with a high level of disappointment.”

Waugh said he’d been inundated with messages from people expressing pride in the Wallabies’ performances, and said the atmosphere of a record 90,307 crowd at the MCG had created one of the most memorable sporting events seen at the venue.

“And a lot of the feedback that I’ve received from people who travel the world going to sporting events, was that match was as good as they’ve ever been anywhere in the world,” Waugh said.

The RA boss said there expressed confidence the third Test in Sydney would still be a massive event despite being a dead rubber, and though some tickets are still available, the game is on track to sell out.
