Both teams had to overcome their fair share of adversity along the way in front of a sold-out HBF Park on Sunday.
John Manenti's side managed to scrape into the quarter-finals before knocking off the USA and defending Commonwealth champions Fiji on their way to a rematch with Argentina.
James Turner (gastro) missed the majority of the tournament whilst Henry Hutchison was eased into the event on his return to the Sevens circuit.
"We're not quite where we need to be and it's important that we learn to be in that environment and we're fighting for medals," Manenti said after the Final.
"I think it's the first time we've been in back-to-back finals since 2015, which is a really good achievement for the boys.
"What I'm striving for as a group is consistency. And so if we can put ourselves in that position, to be competing for medals, regardless of colour - the more exposure we can have with that, the better we're going to be playing under pressure."
"They just completely starved us of possession, it's tough to win when you don't have the footy," Australia captain Nick Malouf told Stan Sport on the defeat.
As for the Women, almost everything that could go wrong did.
Maddison Levi missed the start of the tournament and lasted five minutes before her second red card in as many games left her shattered on the sidelines. She was joined by sister Teagan until the Final after her high shot against Great Britain on day one.

Captain Charlotte Caslick, who was yellow carded in the Final for a deliberate knockdown, lamented the lack of discipline after a taxing weekend.
"We would have loved to have come away with a win. But I think the emotion and the lack of discipline throughout really let us down," she said.
“We definitely dealt with a lot of adversity and had lots of scenarios to learn from. Losing ‘BB’ (Bienne Terita) in the semi-final hurt because she was playing incredibly, probably the best in the tournament.
“Credit to Ireland. The depth in the World Series continues to grow. David Nucifora (Ireland’s high-performance chief) is an Aussie and has been a huge influence in Irish rugby improving.”
