The comments were enough for Channel 4 to cut ties with the player, who had been signed up as the face of its European rugby coverage.
Folau, a devout Christian, posted a picture on social media on Wednesday which included the words: "Warning".
"The comments and the post that Israel Folau has made, not just in the last 24 hours but also a year ago when he was in the press for the same things, he doesn't represent me, and for that reason, I think he's left Rugby Australia with only one choice and that's to sack him".
'Following today's meeting the two organisations will update their respective Boards on the matter to consider next steps.
Rugby Australia is set to terminate Folau's contract, just months away from a World Cup at which he would have been a central figure for the Wallabies.
But any hope of Folau returning to the game in which he made his name is now gone and his future now appears to lie in overseas rugby union.
RUPA will work alongside Israel and his representatives, the NSW Rugby Union and Rugby Australia to ensure that this process is followed.
"In the absence of compelling mitigating factors, it is our intention to terminate his contract".
Vunipola, who plays for the Saracens and the England national team, later made his own post defending Folau, adding: "There just comes a point when you insult what I grew up believing in that you just say enough is enough, what he's saying isn't that he doesn't like or love those people".
As he approached his auto, the news crew asked if he regretted his social media posts. "This is my position on it", he said on his Instagram page. Get excited about rugby in Australia and rugby in Canberra and hopefully we can get a good crowd tomorrow night.
"He's put himself before the game, he's put himself before his team-mates and I think he's isolated himself to the point where there's only one decision for Rugby Australia, where he has to go", Mitchell told Fox Sports.
"When people of influence use their public profiles to demean and discriminate, we can not allow such divisive comments to go unchecked".
