Casey Dellacqua became the latest Australian to reach the third round of Wimbledon, producing a convincing performance to topple No.17 seed Elina Svitolina on Thursday.

However, it wasn't such a good afternoon for fellow Aussie Ajla Tomljanovic, winning just one game in the 6-0, 6-1 demolition at the hands of Poland's Agnieszka Radwanska.

Dellacqua, who is yet to drop a set in the tournament, has joined Sam Stosur in the third round and now faces the red-hot Radwanska.

While Stosur and Dellacqua are left to fly the flag in the ladies draw, Bernard Tomic, Nick Kyrgios and Sam Groth are still alive in the men's section.

Tomic will take on world No.1 Novak Djokovic, while Kyrgios has a date with Milos Raonic - the Canadian who ended his giant-killing run at Wimbledon last year.

Sam Stosur will square off against Coco Vandeweghe while Groth has a shot at No.2 Roger Federer.
