Pusey was arrested this month and has been remanded in custody ever since.
Pusey dialled in by phone to Sunshine Magistrates Court on Tuesday and revealed the gender move to magistrate Cynthia Lynch.
"Is Mr Pusey on the line?" she asked the court.
"My pronouns are they/them," Pusey replied.
The accused then asked why they kept getting brought before the courts, citing comments made by the Victoria Police secretary Wayne Gatt.
"Wayne Gatt made a statement saying justice for people like Richard Pusey isn't done in courts," Pusey said.
"So where is it done?
"I'm a bit miffed about why I keep being brought into a courthouse."
Lynch said: "You're here for a mention. I can't assist you with third party comments."
And when asked whether Pusey wanted to contest the media applications in the matter, they said: "Nah, that's fine, just make sure I get front page".
Police allege Pusey made the post to the Porsche dealership just a few days after a state memorial service was held at Marvel Stadium to remember the lives of Leading Senior Constable Lynette Taylor, Senior Constable Kevin King and Constables Josh Prestney and Glen Humphris.
Pusey was sentenced to 10 months jail last year after pleading guilty to the rare charge of outraging public decency for filming the aftermath of the crash.
Pusey made no application for bail and the matter will return to court on March 23.
