Australia has done the double at the Central Coast Sevens, beating Fijian Barbarians 19-17 in the final.
The Australia Gold team held off the Fiji team in the final to top their 2016 runner-up finish.
It's the Aussies' second win in as many tournaments, after coming out on top in the invitational Oktoberfest 7s in Munich.
Australia coach Andy Friend said that win gave them plenty of confidence, something that was beginning to show.
"They often say losing can be contagious but winning is also contagious and it breeds confidence and the boys have definitely got confidence," he said.
"We won’t get ahead of ourselves but for the players, they've got real belief as individuals and the systems of the team and everything."
Australia Green finished fifth after going down to Fijian side Tabadamu in the quarter-final, Friend pleased with their ability to rebound in the plate competition.
Friend praise the leadership of Jesse Parahi in that green team, with the returning star captaining the side and bringing plenty of experience to the team.
"He was the captain there, he's been key player for us for a long while in sevens and it was his first tournament back," he said.
"He was immense, he guided the young blokes very well so really a credit to him."
Australia will play in the Oceania Sevens in a fortnight as their preseason continues.
