Roger Federer beat compatriot Stan Wawrinka in five sets Thursday to reach his first grand slam final since the US Open in 2015.

On that day, Serb Novak Djokovic overcame Federer 6-4 5-7 6-4 6-4 to win his 10th major title.

Federer's last slam title came almost five years ago, when he beat Andy Murray in the Wimbledon final in 2012.

Earlier Thursday, Serena Williams beat Croatian veteran Mirjana Lucic-Baroni in straight sets to reach her 29th grand slam final.

Older sister Venus was also victorious in her semifinal, overcoming Coco Vandeweghe to reach her first major final since Wimbledon in 2009.

Venus's most recent major final appearance also marked the last time the Williams sisters met in a grand slam final. Serena came out on top that day, winning in straight sets.

Rafael Nadal will take on Bulgaria's Grigor Dimitrov Friday for a place in the Australian Open final. It would be the Spaniard's first major final since beating Djokovic to the 2014 French Open title.
