The deputy principal of a Melbourne Catholic school is facing fresh allegations of producing child pornography following his arrest in March.

Quentin Paul Smith, 49, who resigned from St John’s Regional College in Dandenong after he was charged, fronted Melbourne Magistrates Court on Friday morning.

The court heard a special application had allegedly been downloaded onto Mr Smith’s home computer in an attempt to "prevent" downloads from being detected by police.

And on one occasion police say Mr Smith allegedly accessed 367 files relating to child pornography during a 37-minute period - equating to one file every six seconds .

He lives alone, the court heard.
