Ash Barty will begin her Australian Open campaign against Ukrainian world No.120 Lesia Tsurenko and should comfortably progress through the first week at Melbourne Park.

But then the world No.1’s path to Open glory could become treacherous.

Barty may have to beat her 2019 Wimbledon slayer Alison Riske, Petra Kvitova, who dumped her from the quarterfinals last year, and defending champion Naomi Osaka or seven-time winner Serena Williams in successive matches to make the title decider.

Thursday night’s draw pitted Barty in the same top half as third seed Osaka and eighth seed Williams.

The men's and women's singles draws are complete:

Grand Slam draws, though, rarely pan out as predicted and Barty will be focusing solely on her opener against Tsurenko on Monday.

The Ukraine was ranked as high as 23rd in the world after reaching the 2018 US Open quarter-finals.

If she progresses, Barty – who repeated her 2019 French Open triumph over Marketa Vondrousova to storm into the Adelaide International semifinals –will play world No.44 Rebecca Peterson or the 48th-ranked Polona Hercog in the second round.

World No.36 Elena Rybakina is her projected third-round opponent, with world No.14 Petra Martic or 18th seed Riske – who abruptly ended Barty’s 15-match European winning streak last July in London – likely to be lying in wait in the last 16.

Barty potentially faces Kvitova in the quarters and Osaka or Williams in the semis, with world No.2 Karolina Pliskova heading up a softer bottom half of the draw also featuring Wimbledon champion Simon Halep.

Nick Kyrgios will open his campaign against unseeded Italian Lorenzo Sonego.

With Alex de Minaur forced to withdraw through injury, Kyrgios will be Australia’s top men’s hope when the season’s first Grand Slam begins on Monday.

Seeded 23rd, Kyrgios’s first big test is likely to come against Russian star Karen Khachanov in round three and the former quarterfinalist could run into world No.1 Rafael Nadal in the round of 16.

In-form 2018 US Open quarter-finalist John Millman will open his campaign against rising Frenchman Ugo Humbert, while Davis Cup teammate Jordan Thompson plays Kazakh Alexander Bublik.

Young gun Alexei Popyrin, who made the third round last year, has a tough opener against former finalist Jo-Wilfried Tsonga.

James Duckworth opens against Slovenian Aljaz Bedene, Chris O’Connell takes on Russian 17th seed Andrey Rublev and fellow wildcard Andrew Harris can expect a show-court showdown with eighth seed Matteo Berrettini, a US Open semi-finalist last year.

Marc Polmans meets Mikhail Kukushkin and Alex Bolt, who was also awarded a wildcard following his charge to the last 32 in 2019, plays Spaniard Albert Vinolas Ramos.

Wildcard playoff winner  John Patrick Smith faces Argentina’s 22nd seed Guido Pella.

Other highlights of the draw included six-times winner Roger Federer landing in the same side as seven-times champion Novak Djokovic and Venus Williams plucked out to meet 15-year-old American sensation Coco Gauff in a repeat of their 2019 Wimbledon opener – which the teenager won before reaching the fourth round.
