The Atlanta win pushed Australia out to 60 points, 14 clear of New Zealand with just two rounds remaining. The team has been drawn in Pool B at Langford and will play USA, Fiji and Spain.
Debutants in Atlanta - Theresa Fitzpatrick, Terina Te Tamaki, and Stacey Waaka - have the chance to impress again with only one more tournament (France) left in the season before the New Zealand Olympic sevens team is selected in early July.
"We made some real progress in Atlanta with a very young side," said Horan. "Seven players had never tasted the pressure of finals sevens rugby before so that's great experience to bank. We'll certainly be looking to build on that in Langford where another tough pool awaits us."
