Despite their success, the girls revealed on Sunrise that they still can't believe they are now $250,000 richer.
"We're still in shock!" Gracia laughed when asked how it felt to be part of the winning team.
Fighting back tears as they were announced as winners, Gracia said, "I think it’s the greatest achievement that we have ever accomplished and we did it together which makes it more special than anything else."
But just what was going through their minds as they were waiting for their final scores to be revealed?
"Most of what we were thinking was, 'all the hard work is finally over', but there were a lot of mixed emotions," Gracia said.
The second group of sisters to win the competition in the show's history, the girls became fan favourites thanks to their hilarious mid-cook arguments.
"We spend a lot of time with each other and we argue a lot," shared Tasia.
"But our relationship is we fight and then we forget the next day, or the next minute."
Hinting during last night's finale that there was a 'sauce business' on the cards, the sisters revealed on Sunrise that their dream is well under way.
"We have a [peanut satay] sauce that's ready to come out, we're just waiting for the right time," the girls teased.
