A feral pig, which made international headlines after stealing beer from a campsite in Western Australia's northern Pilbara region, has died.

Witnesses last month said the animal drank up to 18 cans of beer at the DeGrey River rest area, east of Port Hedland, before ransacking bin bags and causing a nuisance.

Fionna Findley from Main Roads says crews have confirmed the same animal - nicknamed Swino - was recently hit by a vehicle about 1 kilometre north of the rest area.

"These guys went out and they could see that apparently Swino had some really distinct markings on his ears," she said.

"And just the colouring of him they were able to match up the markings from what they found to some of the photos."

Swino caused several headaches for holidaymakers earlier this year.

One camper named Merida recounted the tale told to her by fellow campers.

"It was in the middle of the night and it was these people camping opposite us and they heard this crunching of the can and they got their torch out and shone it on the pig and there he was scrunching away at their cans," Merida said.

"Then he went and raided their rubbish that they had sort of covered over with a bin as well.

"And then there was some other people camped right on the river and they saw him running around their vehicle being chased by a cow."

Meanwhile, a cafe in Sydney has posted a $5,000 reward for a pig named Kevin Bacon and a lamb named Bradley after they were stolen early this morning.
