The 28-year-old pleaded not guilty to killing six people on Bourke Street in January 20 last year.
A jury took around an hour to find Gargasoulas guilty of all charges.
During the trial it was revealed that a detective had been sending text messages to Gargasoulas just minutes before the tragic incident occurred, trying to get him to surrender, to which he replied that he was the saviour and that Earth was destined to be hit by a comet.
During the trial on Monday afternoon, Gargasoulas told the court that he’d had a premonition about hitting pedestrians ahead of the incident. He also spoke of a comet hitting Earth, the Illuminati, Muslim freedom fighters, upholding God’s law, and government oppression.
