According to the Sunday Telegraph, Efron was airlifted to private hospital St. Andrews War Memorial Hospital in Brisbane, was hospitalised for several days. He was then given the all-clear and allowed to fly home to the US on Christmas Eve.
Efron's new show, as the title suggests, revolves around his survival. For the show, Efron "heads deep into the jungles of a remote, dangerous island to carve his own name in expedition history." He spends 21 days in the wilderness with only basic gear and a guiding partner.
"I tend to thrive under extreme circumstances and seek out opportunities that challenge me on every level," Efron said when the series was announced last month. "I am excited to explore any uncharted territory and discover what unexpected adventure awaits!"
Per the Telegraph, Efron's flight to Australia was a matter of life or death. Dr Glenn McKay, Director of Medical Rescue, oversaw Efron's emergency flight but could not discuss details with the newspaper. He said that medical professionals "retrieved a US citizen in his 30s from PNG to Brisbane for medical attention in Australia."
Understandably, fans were concerned when they heard the news.
