England picked up their first tournament victory of the season on Sunday as they saw off New Zealand in the final of the Canada Sevens.
This was the first time this campaign that Australia didn't lift the Cup as they were knocked out by England during the semi-final stage.
England won the tournament in British Columbia after beating New Zealand 31-14, with captain Emily Scarratt delighted with the victory.
"I'm thrilled with the performance. We knew that if we played the way we know we can, we could get to the final," she told World Rugby.
"It was a really tough match against New Zealand but we stuck to the system. The first half was ping-pong in terms of tries but we stuck to our systems and we've our reward now.
"We've now got a few days off when we get home, as we're absolutely shattered after a back-to-back set of tournaments. But it's a great feeling."
England Women's coach Simon Middleton added: "The girls were absolutely outstanding today, executed the game plan to a tee and played with loads of composure and energy. Our defence was particularly good against Australia and New Zealand and i couldn't be more proud."
Host nation Canada won the Plate, seeing off Spain, while Australia claimed third place after beating France in the Bronze Medal fixture.
