We spotted many famous faces at the tennis on day four.

Alex De Minaur’s night match was the main drawcard – spotted in the crowd were AFL legends Eddie Betts and Adam Goodes, former federal treasurer Josh Frydenberg and ex-tennis player, and former Victorian deputy Liberal leader Sam Groth, who was joined by wife Brittany and tennis legend Lleyton Hewitt’s wife Bec.

During the fourth set, five-time Olympian and beach volleyball gold medallist Natalie Cook even ran up from her front-row seat to take a selfie with the Groths while Bec Hewitt left Rod Laver Arena for a quick break.
