Jackman, who walked the red carpet at the New York premiere of his new sci-fi action thriller Chappie, talked to ET's Jason Dundas about his affinity for Instagram.
"Well, come on. I'm Australian," Jackman said, laughing.
Jackman added that his drinking photos are a bit of a travelogue documenting the places he's gone while promoting his films.
"Every country you go to you have to have something very particular to drink that's local," Jackman explained. "It's part of traveling."
