Oscar Diaz Ysuiza, 23, faced Melbourne Magistrates Court on Tuesday, about a month after federal police charged him over an incident at Melbourne airport.
Australian Federal Police will allege the Greenvale man performed a Nazi salute, which was directed towards a group of Jewish school-aged children, inside the airport terminal on February 2.
Ysuiza allegedly left the airport shortly after and the incident was reported to the AFP.
AFP members reviewed CCTV and interviewed witnesses to identify Ysuiza, before visiting him at a Greenvale home, in Melbourne's north, later that day.
Police identified he was an airport employee and found that he held an Aviation Security Identification Card, AFP said.
Ysuiza was charged on summons with one count of making a Nazi gesture in a public place in circumstances where doing so is likely to offend, insult, humiliate or intimidate.
The offence carries a maximum penalty of five years in prison.
Ysuiza sat behind his legal aid lawyer as upcoming court dates were set, and left the court to awaiting media where he covered his face with a cap.
He will return to court on May 26 for a committal mention.
