South Australia's dangerous and dilapidated Big Lobster will have to be torn down unless his owners can raise tens of thousands of dollars for repairs.
After more than 35 years in Kingston, in the state's southeast, 17 metre-high Larry has a partially-detached leg that swings in the wind, co-owner Frances Curkpatrick says.
"He's very badly deteriorated. He's getting to the danger stage," she told AAP.
"If he doesn't get the work done, he has to come down and I don't want to do that....the people of Kingston love Larry."
Mrs Curkpatrick this week started an online campaign to raise $30,000 for repairs by Christmas and said she had received more than $700 in 24 hours.
"You can just put your finger on his exterior and basically push through to the foam," she said of Larry's condition.
"People come down this way to see him and it's really embarrassing because he's in a really bad condition."
Larry is located on the grounds of the Humbugz Honey restaurant, which Mrs Curkpatrick runs, at Kingston and has been a tourist drawcard in SA's southeast.
