Bloomfield swaps with Trevor King, with the Souths prop reverting back to the bench.
In the backs, Archie Saunders returns to the back three after missing the defeat to Italy.
Austin Durbidge comes onto the bench as Grey has named a 6-2 bench split, with Waratahs teammate Billy Dickens and Boston Fakafanua set to cover the backs.

Australia needs to defeat top-ranked Ireland and deny them a bonus point if they wish to ensure their qualification for the semi-finals.
They currently sit in second place in Pool B, with the top sides from each Pool and the best-ranked second-place finisher qualifying for the finals.
Captain Toby Macpherson called for a response after the five point defeat to the Italians with their tournament on the line.
"I don't think (the game) slipped away, we just missed our opportunities in the A-zone. We created plenty of opportunities, we've just got to be better at executing them," Macpherson told broadcaster RugbyPass TV post-game.
"You can say it rained or it was windy but at the end of the day, we've got to get better and that's what we're planning on doing this week leading into Ireland.
“…They (Ireland) are a really good team, a class outfit, but they've got points that we'll attack and no doubt they've got points on us. The boys have got to get up, swallow the tough pill today, back it up this week at training, get better and get better quick.”
