One of the district's most famous residents, Wilbur the Pig, has finally passed on to Piggy Paradise after the 300kg hog died on Thursday.

A Facebook group created for Wilbur - the Rokewood Pig Appreciation Society - has been flooded with messages of condolences.

Wilbur, who was 17 years old, took a turn for the worst in early May, his hips and back legs increasingly unable to carry his bulk. According to his long time owner and friend Gwen Mills, when a pig's back legs go it generally means their days are nearly over.

"He had to be put down because he couldn't move anymore. He couldn't even get up. We didn't want him to suffer," Gwen Mills said. "He is buried in the paddock.

"My granddaughters have received literally hundreds of messages on Facebook. It is quite amazing really."

Ms Mills gave Wilbur to her grand daughter Alyssa as a birthday present 17 years ago. He was raised by Ms Mills along with Alyssa and sister Mikayla.

Wilbur became famous as the big black pig in the paddock on the corner in Rokewood.

He was a de facto mascot for the Rokewood-Corindhap Football Netball Club and apparently loved a beer.

"Because I live where I live, he was right in the middle of the intersection between Geelong, Colac, and Ballarat, so people would see him all the time," Ms Mills explained.

"There was a little boy, for example who saw him when he came through Colac every week since the age of two. That boy is now 17."

Ms Mills said a memorial for Wilbur would be placed in the paddock he lived his long life. She said 17 years is a remarkably good innings for a pig.

"The girls say anyone who wants to put flowers on his grave, they are most welcome," Ms Mills said
