Coach John Fletcher was understandably delighted with his side in all aspects of their game. He said: "I'm very, very pleased. It was a great game of rugby - we both passed the ball around and scored some fine tries. Who says teams in the Northern Hemisphere can't play rugby?
"I knew that Australia would be dangerous in broken play and they lived up to expectations, but we stuck with it and I thought that for large parts of the game we were the better side.
"We played some good rugby and we kept going at the end, which was great."
England were in contention at the interval thanks to a smart piece of work by scrum-half Dan Robson at a quickly-taken throw-in, the No 9 seizing the chance to catch Australia napping and give lock Dominic Barrow time and space to gather the ball and dive over for the first try of the game after 18 minutes.
Fly-half George Ford hit the woodwork with the conversion, but he was successful with penalty kicks after 22 and 30 minutes to keep his side in the hunt.
The tourists were always threatening in broken play and created a handful of openings with strong counter-attacking, but it was not until first-half injury time that the tourists finally broke through with a try by No 8 and captain Jordan Tuapou.
Fly-half Rohan Saifoloi added the conversion to his earlier hat trick of penalties to give the tourists a 16-11 half-time advantage, but that was short lived as a penalty try for deliberate knock-on, converted by Ford, restored England's lead.
The second-half was a frenetic nip-and-tuck affair to the final whistle, tricky wingman Kimami Sitauti twice rounding off smart handling movements for tries for the tourists and Saifoloi adding a conversion.
England, however, stuck tenaciously to the challenge, edging in front with a smart try from replacement scrum-half Joel Hodgson 21 minutes into the second-half and then snatching the prize in the closing minutes when Hodgson was held just short after a flowing movement from inside their own half and Bell was on hand to drive over.
