Tough test next for Juan Martin del Potro
Smooth second-round successes for Djokovic and Federer
Six-time Australian Open champion Novak Djokovic eased past Gael Monfils in his second-round encounter and will tackle Spaniard Albert Ramos-Vinolas next.
The Serb, who is as short as 1-10 to oblige, has won all four of their meetings without dropping a set and is likely to book his place in round four.
Roger Federer's title defence gathered pace with a smooth success over German Jan-Lennard Struff and the Swiss legend is 8-13 to record a third straight-sets victory over Richard Gasquet.
Federer breezed past Aljaz Bedene 6-3 6-4 6-3 in his opener before blitzing Struff 6-4 6-4 7-6 and shouldn't be dismissed in his bid to bring up a hat-trick of easy wins.
The game of the day sees Juan Martin del Potro tackle giant Czech Tomas Berdych and bookmakers are finding it difficult to split the pair.
Del Potro is rated slight favourite at 4-6 but the Argentinian needed four sets to see off Karen Khachanov in the last round while battling an apparent injury and punters should tread carefully.
Just ten of the top 20 seeds remain in the women's event and two Melbourne winners, Angeligue Kerber and Maria Sharapova, lock horns in a highly anticipated third-round encounter.
Kerber, the 2016 champion, is slightly preferred at 8-11 but there's little to split them if they are both at their best. The last three meetings have gone to a deciding set and bet365 go 5-4 about the match going the distance.
