Australian Open 2017 is officially underway. Broadsheet was there on the first day of the tournament to catch the action on and off the court.

As some of the world's best tennis players slugged it out inside Melbourne Park, the public descended on Birrarung Marr to take in the carnival atmosphere of the AO Festival. Perth band Birds of Tokyo played on the AO Live Stage, as crowds flocked to the food and drink offerings, including Tokyo Tina, Huxtaburger, Hotel Jesus, Jimmy Grants and refreshments from the Canadian Club Racquet Club.

The AO festival runs until January 29 in conjunction with the tournament. Entry is free. (Access to the AO Live Stage requires a grounds pass.)
