World No 3 Coco Gauff began her Australian Open campaign in style on Monday but former finalist Stefanos Tsitsipas became the biggest casualty of the tournament so far. Novak Djokovic begins his bid for grand slam history later on a blockbuster day two and Jannik Sinner starts the defence of the trophy he won 12 months ago.

Defending men’s champion Jannik Sinner, Carlos Alcaraz and Novak Djokovic all play, with Nick Kyrgios leading Australian hopes. They are joined by Iga Swiatek, Coco Gauff, Ons Jabeur, Danielle Collins and Naomi Osaka on a star-studded day’s play. Here’s what to watch on the three biggest show courts and around the grounds.

Defending champion Jannik Sinner and 10-time Australian Open winner Novak Djokovic have landed in opposite sides of the draw for the season’s first major, ruling out a replay of last year’s semifinal encounter.
