Nick Kyrgios was the star of the show winning the first ATP Cup tie against Stefanos Tsitsipas for the second time 7-6, 6-7, 7-6 in a close ran affair.
John Millman nearly fluffed their lines though playing as a substitute against No.486 Michail Pervolarakis, who went 7-8 last season on the ATP Challenger Tour but claimed it 4-6, 6-1, 7-6.
John Peers and Chris Guccione made it a clean sweep from there by defeating Markos Kalovelonis and Petros Tsitsipas 6-3 6-4 and next up for the Aussie's will be Great Britain in the Last Eight.
The Australian team though have established themselves this past week though as potentially the team to beat and they will hope to live up to that against their fellow Group winners.
