The Australians also suffered an upset defeat to Fiji on Saturday and will need to focus on their defensive woes ahead of Tokyo next month.
Head coach John Manenti said the results may not show it, but he saw positives with the squad's improvement.
"I thought we stepped up across the park with our whole performance," he said.
"We worked really hard and made them work hard for their tries...we asked a few questions to them and probably probably should have asked a couple more.
"But ultimately, I thought we were much better tonight than we have been against New Zealand for a little while."
Fiji remained undefeated through the tournament to take out the men's competition, while New Zealand's Black Fern's won all of their matches on their way to the Oceania Sevens title.
