The duo lost to Germany in three sets in the quarter finals 23-21, 15-21, 15-17, a day after upsetting the top-ranked team in the world, Agatha Bednarczuk and Barbara Seixa from Brazil.
Seixa said the Melanesians were better than them on the day and deserved all the credit for handling the wind better than they did.
Miller Pata says it's Vanuatu's greatest moment on the world tour and like a dream come true.
Their fifth-placed finish matches their best effort at a World Tour event.
They now head to Poland for another Grand Slam.
