Venus and Serena Williams will meet in a Grand Slam final for the ninth time after the American sisters came through their semi-finals in Melbourne.

Thirteenth seed Venus, 36, beat fellow American Coco Vandeweghe 6-7 (3-7) 6-2 6-3 to reach her first major final since 2009.

World number two Serena, 35, saw off unseeded Croat Mirjana Lucic-Baroni 6-2 6-1 in the second semi-final.

Serena is attempting to win an Open-era record 23rd Grand Slam singles title, informs BBC.

It would also be a seventh Australian Open victory for the younger Williams sister, while Venus hopes to win an eighth major title, first in Melbourne and first since Wimbledon in 2008.

Saturday will be their first Grand Slam final against each other since Wimbledon 2009 when Serena won in straight sets.
