A Melbourne man has been found guilty of plotting terror attacks targeting buildings including Trades Hall and creating a handbook for wannabe attackers.

Right-wing extremist Phillip Galea, 35, was found guilty of planning and preparing a terror attack after he spoke to an associate about targeting a left-wing rally with chemical bombs.

He had looked up the addresses of the union movement's Trades Hall headquarters, the Melbourne Resistance Centre and the city's anarchist club, the court heard.

Galea was also found guilty of creating a document called the "Patriot's Cookbook", described as a terrorist how-to-guide by prosecutors.

Galea - who was associated with the far-right group Reclaim Australia - insisted the first version of the guide was meant to be a Monty Python-esque satire.

"You weren't given all the facts," the convicted terror plotter yelled out as the jury members were being taken from the courtroom on Thursday.

He was found guilty by the Victorian Supreme Court jury after deliberating for about two days following a seven-week trial.

Galea was arrested in August 2016 at his Melbourne home, after arson and explosives experts raided his home in November 2015 and seized five cattle prods and 362.1 grams of mercury.

Computer equipment was also seized, and it's alleged Galea researched homemade bombs, ballistic armour and guns.

Galea described himself as a self-taught electrical engineer who was using the mercury to replicate an engine originally created by 19th-century English scientist Michael Faraday.
