The solid 6-4, 6-3 victory gave the Williams sisters, the No. 2-ranked team, five doubles championships in the last seven major tournaments. They've entered 17 majors as a doubles teams, winning 11 of those events.
Friday's win was the fourth Australian Open title for the Williamses, who took the championship in 2001, 2003 and 2009. The 2010 Australian Open title means the Williams sisters hold the last three doubles titles, having taken first at last year's Wimbledon and U.S. Open events.
World No. 1 singles player Serena Williams will be in action Saturday in the women's singles final against Belgian Justine Henin.
The doubles championship comes with a check for $400,000. If Serena wins the singles title, she'll pick up an additional $1.8 million.
