The opening 63-3 win over Italy was a strong start for the English but Moriarty knows that there were aspects of the game that they must improve on leading in to the clash with Australia on Friday (KO 6:35am BST).
"There were parts of the game against Italy where we were struggling to score, and to be honest we left a few tries out there. It was a tough physical game as expected.
"We've watched the Australians in a few warm-up games they've had, as well as the game they had against Argentina on Monday and they're quite similar to us in the way that they play. So we're expecting a really tough game but I really can't wait for it."
Speaking to the local media this week, David Humphreys insisted that Gloucester are looking forward to kicking off the new European Rugby Challenge Cup against Brive on Thursday evening, although an unfamiliar opponent and a five day turnaround will pose a challenge.
Director of Rugby David Humphreys felt that his Gloucester side put themselves in a position to put Saracens under real pressure at Allianz Park on Saturday, praising his team's commitment and defence, while admitting that a lack of accuracy hit their chances in the second half.
Speaking to the local media at Allianz Park, Tom Savage was disappointed after the defeat at Saracens, but claimed Gloucester did plenty of good things and could've taken more than a losing bonus point.
In case you missed it, there was plenty of activity on the official Gloucester Rugby website following the 55-0 European Rugby Challenge Cup win over CA Brive, including a number of post match video interviews.
