Top-seeded Rafael Nadal advanced easily to the third round with a 6-2, 6-4, 6-2 win over another Australian, Thanasi Kokkinakis.
Roger Federer also looked impressive in his second round match versus Blaz Kavcic, racing to a 6-2, 6-1, 7-6(4) win.
Defending champion Victoria Azarenka held firm for a 6-1, 6-4 second-round victory over Barbora Zahlavova.
Fifth seed Agniezska Radwanska raced to a 6-0, 7-5 win over Olga Govortsova before play was suspended.
