It was written off as a hoax by many, including WA’s Department of Environment and Conservation, and sparked much debate when published on website PerthNow.
But The Sunday Times has confirmed that the pig was shot on a Pilbara cattle station near Newman, 1200km northeast of Perth.
Sources close to the family of the man in the photo have confirmed he is Pilbara pastoralist John Anick and the picture was taken on his property three years ago.
The source said the 220kg beast was eating a cow when it was first seen by workers mustering cattle in a helicopter. Mr Anick saw it again on a trip to check windmills on the property and shot it.
Another source working in Perth claimed to have scanned the original photograph into a computer.
Hoax-Slayer.com says an article in the January 2007 edition of Sporting Shooter also states the boar was shot on a cattle station in the Pilbara.
There are estimated to be more than 23million feral pigs roaming the nation, predominantly in New South Wales, Queensland and the Northern Territory.
They prey on native species and destroy habitats.
