The order of play for Tuesday at the Australian Open has been released, and it's a big day on the women's side of the draw.
Top seed and home favourite Ashleigh Barty enters the draw, taking on Montenegro's Danka Kovinic - and both of last year's finalists are in action as defending champion Sofia Kenin faces Aussie Maddison Inglis and runner-up Garbine Muguruza plays lucky loser Margarita Gasparyan.

Rafael Nadal, seeded second here, begins a quest for a 21st Grand Slam singles title - in the absence of his current co-record holder Roger Federer. He plays Laslo Djere of Serbia - the first time the two have encountered each other.
Elina Svitolina will not have an easy ride against Marie Bouzkova. The Czech is in decent form, testing out her skills in singles and doubles in the warm-up events in Melbourne. The two have only met twice before, and have one win apiece.
One Brit will definitely be going through to the second round as Dan Evans, seeded 30th, takes on Cameron Norrie at the end of the day on Court 9.
At around the same time, women's number one Johanna Konta, the 13th seed, will come up against qualifier Kaja Juvan.
Heather Watson faces Kristyna Pliskova on Court 10, while qualifier Fran Jones has a very tough task against Shelby Rogers of the USA out on Court 5.
