Wade Ormsby and Sam Brazel won their group on day one and entered the knockout stage among the favourites but lost a tense semi-final against the French pair of Romain Wattel and Mike Lorenzo-Vera.
The Australians began the day with a 2-0 victory over the European Women’s team of Mel Reid and Carlota Ciganda, back t back birdies at the fourth and fifth holes enough to take the match.
The French started fast in the semi-final with a birdie at the first but the Australians levelled the score at the very next with a birdie of their own.
Managing only a par at the par-5 third proved crucial as they fell behind again then made the fatal error at the fourth with a bogey.
When both teams birdied the fifth the French advanced to the final where they met a red-hot Irish team.
The Australians were flat in the consolation match and didn’t make a single birdie as Jeunghung Wan and Soomin Lee dispatched them three pints to nil.
Meanwhile Ireland’s run to the final saw them account for the England Women’s team of Charley Hull and Georgia Hall in round one, make a chip in birdie to beat South Korea in a play-off in the semi-final before overcoming France comfortably in the final match.
Dunne and Moynihan were teammates in the 2015 Walker Cup but their professional career paths have been somewhat different, Dunne a European tour winner already while Moynihan has struggled.

However, they teamed well in the quirky six-hole greensomes format with Moynihan making a crucial contribution when his chip in birdie guaranteed the team a place in the final.
"When you have the tricolour besides your name it becomes a little bit more serious," said Dunne after the win.
"We're happy to represent Ireland well, have a nice trophy under the belt and it kind of sets well to kick on for the rest of the season.
"It's an individual game and it's nice to get together with a partner, especially like Gavin, who I've been friends with for a long time, and have success like this.
"We just played really solid all week. Gavin was hitting some amazing iron shots and, obviously, the pivotal moment for us was him chipping in on the play-off against the South Koreans."
While neither of the two women’s teams advanced beyond the semi-final they were a popular, welcome and – more importantly – competitive addition to the field.
They played the six holes a total of 180 metres shorter than the men but all involved were comfortable it made for a fair contest.
England’s Mel Reid declared the event not only a success but an important boost for women’s golf.
"I think it's a huge success for women's golf," she said. "We've hopefully opened a few more eyes to women's golf and that we can compete and that we are pretty good at what we do and we work very hard at what we do.
“Hopefully it's inspired not just a few more young girls but young guys and men, women, all over to take up the game. That's ultimately what we want to do.
"Loads of the girls in America have been saying how much they have enjoyed watching it and Lydia Ko has already messaged us saying she's absolutely desperate to get on a team next year."
