Prabhdeep Srawn, a Canadian-Indian, went missing on May 13 in the Kosciuszko National Park in the Australian state of New South Wales, following which the family had announced a reward of 100,000 Australian dollars for any tip-off.
According to the family sources quoted by Australia's ABC News, the snowy season had begun in the area and the family and volunteers were stopping their search.
Srawn's family continued to search after Australian officials ceased search operations at the end of May and members of the Canadian Forces spent two weeks in June searching the mountain area.
Though the family has been optimistic of finding Srawn as he is a master corporal in the Canadian armed forces, an Australian defence force reservist and has had bushwalking experience, experts feel that the chances of him surviving after so long are slim.
