The Williams sisters Serena and Venus will play against each other in the final of the Australia Open.

Serena eased past the Croatian fairy-tale story of the tournament Mirjana Lucic-Baroni, with a 6-2, 6-1 semi-final win.

Venus had earlier defeated Coco Vandeweghe in three sets- 6-7 (7/3), 6-2, 6-3. At 36 years and 226 days, it made her the oldest woman in the 49-year open era to reach the final

It sets up the women's decider everyone was hoping for.
