The search continues for a student who went off the grid in a small Victorian town four days ago, with police holding grave concerns for his welfare.
In a space of roughly 50 metres, Poshik Sharma went missing in Marysville.
Police and volunteers are to return to the area on Monday in the hope of finding Mr Sharma after he was last seen at the Duck Inn pub with friends on Thursday.
The 21-year-old man left the group after a disagreement before 4pm.
"He has completely gone off the grid which is completely unusual for a young man," Inspector David Ryan told reporters on Sunday.
Mr Sharma has not spoken to friends or family, used his phone or social media since.
A dam has been drained and a walking track and bushland searched to try to find him.
"If he is out and exposed to the elements, he would be a very sick man at this stage," Insp Ryan said.
"We will go door-to-door and check every hidey-hole we can find, for whatever reason he's got shelter in the township."
Mr Sharma had been wearing bright red shoes and scarf, with a black jacket and beanie.
"He's fit, he's strong, with the way he's dressed he should stand out to people," Insp Ryan said.
Friend Prince Teona said they had not told Mr Sharma's parents in India their son was missing, preferring to hang on to hope they will find him first.
"We are trying our best so that we find him before they get to know about that one because he is the only son," he told Nine News.
The temperature is expected to dip to 9 degrees Celsius, with persistent rain and strong winds in Marysville overnight.
