A driver charged over Melbourne's deadly Bourke Street tragedy has made another series of outbursts in court while facing other charges, blaming recent events on the "illuminati".

Dimitrious Gargasoulas appeared from custody by video link in the Melbourne Magistrates Court on Friday morning on unrelated driving and other charges.

He is separately charged with killing six people and injuring dozens by driving his car through busy lunchtime crowds along Bourke Street.

The court today heard that his defence lawyer was still waiting on evidence from the prosecution, as some files were being "utilised by the homicide squad".

Psychological advice will be sought on his ability to enter a plea.

The 26-year-old was twice stopped from interrupting the proceedings before managing to embark on another rant.

Gargasoulas told the court he was "very saddened" by what had happened but his actions were under the control of others.

"I was under extreme stress, which caused me to have a mental breakdown," he said.

"It's not fair, your honour, life is being controlled by the Government.

"I'm very saddened by everything that's happened, but it's due to the illuminati."

Both his lawyer and the magistrate urged Gargasoulas to stop talking and the video link was quickly turned off.

At the last hearing, he declared himself the "saviour" and said "Did you know the Muslim faith is the correct faith according to the whole world? And I am not guilty".

The case was adjourned until July for a further mention hearing when he will again appear by video link.
