After the Christchurch mosque attack that claims 50 lives the man was shocked to discover the identity of the alleged culprit.
"I feel a sense of guilt and have been beating myself up," he told the ABC.
"But at the time I thought I was the only one in danger."
Victoria Police said they had been "unable to locate a complaint made by the victim in 2016".
"Whilst we will not comment on this particular case due to the live court proceedings in New Zealand, we would reassure Victorians that we have strong arrangements in place for monitoring and tracking people who pose a threat to the community."
