Yap last contacted friends and family on 14 September, ahead of a planned 10-day solo trek through Peru's Huayhuash mountain range, 400km north-east of Lima. The Cordillera Huayhuash circuit is regarded as a challenging, high-altitude trek through the remote Andes.
Worry started when he missed his estimated return date. He also failed to check back into the Krusty hostel in Huaraz and missed a scheduled flight from Lima to Cusco. Days before he set off on the 120km hike, he had misplaced the satellite beacon he was travelling with, which raised further concerns.
In a social media post, his friends and family wrote that "with a heavy heart we are sorry to tell you Jordan has been found, and he did not survive." They thanked the search teams, the police, the contributors and everyone who shared the search online. They asked people to remember the immense joy he brought to so many lives.
Australia's Department of Foreign Affairs and Trade confirmed it is providing consular assistance to the family. Citing privacy obligations, a spokesperson said the department could not comment further.
The people who knew him best called him a very experienced hiker.
