Seas during the past week have removed at least another half metre of sand, Mr Findlay said.
"It's got to the stage that we have the potential that one big event could bring an almighty thump and that would be it, we'd have to close.
"It wouldn't surprise me if it happened this winter."
Further heavy seas forecast for the end of the week have compounded Mr Findlay's concerns.
He did not have any quick answers, other than to reinforce his earlier comments that time is of the essence if the camp is to be saved.
Despite raising the need to extend the seawall near the camp last November, "the unfortunate thing is, best case scenario we might get a wall a year later".
"It just takes so long," he said.
"The camp is managed and run by our family and the ongoing stress of the issues surrounding the seawall extension is taking its toll."
The huge seas during the past
week have also taken their toll on Hokitika, particularly around the tiphead near the mouth of the Hokitika River.
Sunset Point remains closed, Westland District Council group manager district assets Vivek Goel, said today.
"It's still closed and is likely to remain like that for the foreseeable future. The situation there is pretty bad."
There was no work planned for the area in the near future, he said.
