The Hollywood star, and part-time muso, has been spotted all over town this week and was among the thousands watching The Killers, Vampire Weekend and the Red Hot Chili Peppers at the festival.
Wearing his trademark baseball cap, check shirt and dark jeans, the Twilight hunk happily posed for photos backstage with John Day and friends.
"He was very cool, very gracious and good humoured ... I asked him how he was enjoying Adelaide and he said he'd only been here a short time and hadn't seen much," John says.
Robert's new movie, The Rover, will be shot in various locations in SA's Flinders Ranges, but the actor admitted to not knowing much about the area.
"I asked him what he (Rob) thought of the Flinders Ranges and he wasn't sure what or where that was, so he had a bit of a laugh about that," John says.
