Foley, who has appeared in five of Munster's seven GUINNESS PRO12 matches so far this season, was named man of the match in his country's win in Dublin.
And he says that the strength of the GUINNESS PRO12 has contributed to the confidence pervading the Irish camp.
"It was absolutely incredible, I suppose I've been dreaming about this since I was a young kid and you never know if you'll get the opportunity," he said.
"There's massive confidence in the squad. The provinces are going very well and Joe is trying to build for the World Cup and trying to get some depth in the squad.
"I think by the looks of things today he has a bit of depth there and fellas are hungry to play.
"But I won't be getting carried away with myself and the team won't be getting carried away with themselves. We've got a massive task next week against Australia."
