Teenager Coco Gauff was handed a first-round showdown against Venus Williams following the draw for the Australian Open.
The 15-year-old was pitted against seven-time Grand Slam champion Venus, who she beat at Wimbledon to make global headlines.
Gauff has built on her breakthrough brilliantly, winning her first WTA tournament at the end of last year to break into the top 100 and earn direct entry to the draw in Melbourne.
Naomi Osaka, seeded third, starts her title defence against Czech Marie Bouzkova, while second seed Karolina Pliskova will take on Kristina Mladenovic and 2008 champion Maria Sharapova will play Donna Vekic in an eye-catching clash.
Serena Williams has landed in Osaka's quarter of the draw with the American starting her quest for a record-equalling 24th Grand Slam against Anastasia Potapova.
French Open champion Ashleigh Barty, the world No 1, will be looking to end Australia's 42-year wait for a home champion since the unseeded Chris O'Neill won the title, when she opens up against Lesia Tsurenko.
Barty faces a potential meeting against Alison Riske again in the fourth round after the American's upset win at the same stage during Wimbledon.
Caroline Wozniacki will begin her final Grand Slam campaign against Kristie Ahn. The Dane will be hanging up her racket after the tournament.
Tricky opening for British trio
British No 1 Johanna Konta has been struggling with a knee injury and was given a tough first-round assignment against the tricky Tunisian Ons Jabeur.
Konta, the 12th seed, has a projected fourth-round meeting with Serena Williams to look forward to.
It's a tough start for Katie Boulter, who returns to Grand Slam tennis after six months out with a back injury, when she faces fifth seed Elina Svitolina, while Heather Watson takes on Kristyna Pliskova.
