An acquaintance who was also living in the house, 23-year-old Gursewak Dhillon, has been charged with manslaughter by criminal negligence.
Autopsy inconclusive
He is due back in court in late June but his lawyers are expected to apply for his bail.
An autopsy has not revealed the cause of death, and police are still awaiting the results of toxicology tests.
After a service held for Gurshan on the weekend, local Darebin councillor Tim Singh Laurence said the Channas hoped to return to Australia in three months.
He said he would use his network to find a job for Mr Channa, who is a welder.
Another service will be held on Sunday at the Mulgrave Community Centre for the Indian community in Melbourne's southeast.
