Dhillon, 23, faced an out-of-sessions court hearing before a bail justice on Sunday evening charged with manslaughter by criminal negligence.
He was remanded in custody to appear in the Melbourne Magistrates' Court on Tuesday.

The toddler's body was found at Oaklands Junction, near Melbourne Airport, about six hours after he disappeared from his Lalor home, about 20km away.
Manpreet Singh, from SBS' Punjabi language radio programme, spoke to the toddler's mother, and said the family did not blame Australia for the tragedy.
Accused lived with boy's parents
Police allege Dhillon, who shared the home with Gurshan's parents and others, placed the boy unconscious but alive in the boot of his car, drove around for at least three hours and then dumped him at Oaklands Junction without checking to see if he was dead or alive.
An autopsy has not revealed the cause of death, and police have given no infirmation on how Gurshan came to be unconscious.
The court case comes after Gurshan's mother, Harpreet Kaur Channa, wrote of her anguish in a letter to the Herald Sun newspaper.
"Our son was a beautiful boy and he was very loved and he is still in the front of our eyes," the letter said.
"Up to this point our grief has been so bad, so deep, so beyond explanation.
"We want to thank the Australian people for their support and the Victoria Police for (making an arrest) so fast."
