Defending champions Venus and Serena Williams beat Cara Black and Liezel Huber 6-4 6-3 to clinch their fourth Australian Open doubles title.
The Williams sisters, seeded second, took 86 minutes to overcome the top seeds - taking a close first set before breaking Huber twice in the second.
Venus, 29, and Serena have collected four of the last six Grand Slam titles and have won 11 in total.
Serena, 28, plays Justine Henin in the women's singles final on Saturday.
Venus admitted the actual moment of their doubles triumph took her by surprise, as she had not realised it was match-point so was not expecting Serena's reaction.
"I actually didn't know the score and I thought that it was 5-2," she said with a laugh. "I thought, she's really happy about this break.
"I thought, wow, I've never seen her this happy, but I'll go with it."
The duo are now the third most successful women's doubles partnership in the Open era, after Martina Navratilova and Pam Shriver (21 Grand Slam titles), and Gigi Fernandez and Natasha Zvereva (14).
Serena says their recent success makes them wish they had taken the doubles more seriously earlier in their career.
"We were talking today about how we wished we had have played more when we were younger," she said.
"We still feel like we have so much we can win and just stay focused. We just love being out there and we love the competition.
"More than anything, we really have fun, we smile and we enjoy it."
