Prabhdeep Srawn of Brampton, Ontario hasn�t been heard from since parking his rental car on May 13 in the village of Charlotte Pass in Kosciuszko National Park.
The 25-year-old has been a law student at Bond University in Brisbane for the past couple of years.
Srawn is also a Canadian Forces reservist and former Australian military reservist, and one family member says he has had extensive survival training.
He is also considered an avid bushwalker.
Members of Srawn�s family arrived in Australia today to aid in the search being conducted by Australian National Parks and Wildlife Service officers, police and State Emergency Service volunteers.
Family members and friends have also posted messages on social media websites hoping to glean any information they can about Srawn�s whereabouts.
