Mladenovic and Garcia admitted that the victory was even more special for them, given that the pair lost three years ago in a decisive match against the Czech Republic.
"Three years ago we failed at the final stage of the tie and today we wanted to get revenge on ourselves. It is impossible to describe how we feel now – said Mladenovic on the pitch after the victory.
Captain Julien Benneteau, who said he would have "a lot of beer" to celebrate until late at night, said he dreamed of this moment at the beginning of the year.
"I am now the most proud man in the world. I am very proud of my girls and my team, they deserve it because they have been fighting for this title for a long time. "
Earlier, Tomljanovic exorcised his debut demons within 24 hours to pull his country back into competition.
Tomljanovic, chosen to play in reverse singles against the world No. 122 Pauline Parmentier, overcame her nerves by winning sets 6-4 7-5 in an extraordinary story of redemption.
Just a day after surrender to a 6-1 6-1 loss in his first match representing Australia, Tomljanovic was again supported by captain Alicia Molik, even after world-wide Barty was defeated in one of the most epic battles in the history competition.
"I'm very happy to have a second chance today," said Tomljanovic after match after match, admitting that she had gone to bed knowing that she would definitely play in reverse singles.
In the first match of the day, Mladenovic came out of the set to beat Barty & # 39; ego in just over two and a half hours in front of another filled house at Perth Arena.
In what the winner described as "epic", Mladenovic finally won 2-6, 6-4, 7-6.
The defeat ended Barty & # 39; ego's next 15 victories and put considerable pressure on the inexperienced Tomljanovic.
After the marathon match, Mladenovic got lost in words, fighting with tears, thanking French fans.
Barty, one of the quietest tennis media performers, looked unhappy when asked if she felt "cramped" at some of the major moments of the match.
"Did it look like this?", She replied.
"I don't think I would, I came back from the failure twice in the third set, and Kiki just played more aggressively.
"From my point of view, I fought as hard as I could, I hope I made my team proud and I hope I made all Australians proud because I fought with everything I have left."
The decisive set was a roller coaster, with four serving breaks, and reached its climax thanks to a tie.
The breaker did not actually symbolize the war of exhaustion, because Mladenovic set foot, knocking over Barty & # 39; ego to take it 7-1.
