The obsessed fan approached Camplin in Fernie, B.C., Canada, a week ago, the Herald Sun reported Monday.
The fan, thought to be American, came down from the stands to tell Camplin he had driven eight hours to see her.
He said he had traveled to Australia last year and visited her home in Melbourne.
"I never really expected to run into someone from overseas face-to-face and then to hear that they'd gone to my home was really scary," Camplin said.
Camplin said the man first began sending letters and gifts after her 2002 Winter Olympics gold medal win.
Barry White, media manager for the Olympic Winter Institute, said there were no recurring problems when Camplin competed in Deer Valley, Utah, over the weekend.
Security was increased following the incident last weekend.
Camplin is currently leading the World Cup standings.
