He said he was not sure that the physical presence of Victoria Police and the ADF in the program would have made a difference.
“There’s been a lot of discussion about the use of Victoria Police and the ADF,” he said.
Mr Helps suggested the presence of the military or police could have intimidated returning travellers.
“These were returning Australians. They were by and large compliant … with a uniform comes a visual impact to people,” he said.
“I’m not sure they would have made a difference, or not have had a subsequent consequential impact in another way.”
But Mr Help’s colleague Andrea Spiteri said a 24/7 police presence in the hotels could have helped.
Ms Spiteri said police could have set an example to security staff.
She told the inquiry she verbally expressed her views on a number of occasions to other department executive staff.
“I just felt there could have been some benefits with having police a bit more visible in that environment,” she said.
As we know, both police and the ADF were on the ground at quarantine hotels in other states.
