The pig first found three six-packs of beer and decided to imbibe.
"In the middle of the night these people camping opposite us heard a noise, so they got their torch out and shone it on the pig and there he was, scrunching away at their cans," one man said.
Then the animal went on an eating binge by sorting through trash bags in the campground.
Campers in the area watched as the pig picked a fight with a cow only to be chased around a vehicle by the bovine.
Having already had its fill of hooch, food, and fighting, the pig then passed out under a tree so he could sleep it off.
The incident took place at the DeGrey River rest area, in the Western Australian town of Port Hedland.
Campers there have been told to take better care of their food, drink, and trash in the future.
