He was granted bail on condition that he report to police five days a week and was due to face a plea hearing Thursday.
Hofstee's father Peter, who came from Queensland for the hearing, said outside court it was extremely disappointing.
'He's in India, I think he's in India,' Hofstee said.
'I would certainly hope the Australian and Indian authorities cooperate to bring him back.
'We obviously indicated we were coming down (for the plea hearing), then they (prosecutors) came back to us to say that he had not been reporting in and they didn't know where he was.
'Subsequent investigations have found that he's flown out of the country.'
Puneet, who was a learner driver at the time of the crash, had pleaded guilty to culpable driving in February.
Police estimate he was travelling at almost 150km/h when he lost control in the 60km/h zone.
Puneet told police in an interview after the smash that he lost control when a cat ran across the road.
