Australian Open: Federer, Nadal and Djokovic's opponents drawn
Roger Federer, Novak Djokovic and Serena Williams headline the Australian Open's first day of play. Defending champion Naomi Osaka is also in action.
The Japanese star gets proceedings underway on Rod Laver Arena when she takes on Marie Bouzkova.
Williams, who is hoping to equal Margaret Court's Grand Slam record over the next fortnight, then follows with her clash against Anastasia Potapova.
Federer completes the day session with his first match of 2020 vs American Steve Johnson.
World No 2 Djokovic has been handed the benefit of a cooler night slot for his battle with Jan-Lennard Struff.
But he must wait until Ashleigh Barty has completed her duel with Lesia Tsurenko.
There are a host of other intriguing match-ups scattered across the rest of the day, especially on Margaret Court Arena.
The pick of the bunch sees the oldest player in the tournament, 40-year-old Venus Williams, take on the youngest, 15-year-old Coco Gauff.
Coincidentally, the pair met in the first round of Wimbledon last year where Gauff announced her name to the world by stunning the seven-time Grand Slam champion.
Next Gen star Stefanos Tsitsipas is also in action alongside a trio of British hopefuls - Dan Evans, Kyle Edmund and Johnanna Konta.
