Wallabies number eight Rob Valetini has been sent off for a high tackle during their clash against Wales.
The visitors were eager to get off to a positive start and found space behind the Welsh line as Andrew Kellaway crossed for the first try.
However, a disastrous period of play saw the Wallabies down to just 13 men.
The incident came in the 14th minute as Wales looked to attack via lock Adam Beard, with Rob Valetini levelling him in the tackle.
This left Beard dazed, with the incident sent to the TMO, ruling a high shot from the number eight.
With the match officials deeming he made no effort to lower his body height, this gave referee Mike Adamson little option but to issue a red card, despite conjecture from former Wallabies winger Drew Mitchell.
"There's no intention there, that's not a red card in my book anyway," he added on Stan Sport.
"His technique was poor but it wasn't foul play."

Whilst the incident caused much debate, Wallabies coach Dave Rennie was comfortable with the decision.
“I don’t have an issue with the red card because that’s how it’s being officiated these days,” he said in his post-match press conference.
“Rob’s responsibility is to drop his tackle height and he didn’t, had a head clash so you have to take it on the chin.”
It marks the second red card for the Wallabies in 2021 after Marika Koroibete was sent off during the third Test against France.
Despite a late fightback, the Wallabies were unable to pull off the win as they went down 29-28 after a penalty after the siren
