A man charged with plotting against left-wing Melbourne groups allegedly tried to make a how-to terror guide he hoped would lead to "thousands upon thousands" of attacks.
Phillip Galea, 34, is charged with preparing for a terrorist attack on the Melbourne Anarchist Club and Melbourne Resistance Centre between August 2015 and 2016.
Galea equated the "left wing" with Muslims and held the former responsible for the "Islamisation of Australia", prosecutor Richard Maidment QC told a Supreme Court jury on Monday.
The accused terror plotter also allegedly worked on a document called the "Patriot's Cookbook", aimed at inciting others to violence.
He said it would lead to "thousands upon thousands" of terrorist acts, Mr Maidment alleged.
The court was told Galea had been associated with the far-right group Reclaim Australia and spoke about targeting left-wing activists at a rally, saying "I could rig some delayed charge chemical bombs".
"They're nothing but criminals working as troops for the left, that think they have impunity," prosecutors recounted from his conversation with a now-dead associate.
When the man replied "no, that's a bloody terrorist attack. Police are on high alert," Galea reportedly replied "terrorist attack on terrorists. Laugh out loud, that's a new one," before adding "OK, you're the boss".
Galea's online search history allegedly included the terms "kill Muslims", "where to find potassium nitrate", "potassium nitrate for sale", and "piano wire to garrotte someone".
He ordered potassium nitrate to use in smoke bombs but listed an associate's address instead of his own, the court was told.
Galea also looked up addresses of the anarchist club, resistance centre and Trades Hall, and also googled prominent left-wing local government councillor Stephen Jolly and former Labor MP for Melton, Don Nardella.
Police raided Galea's Braybrook home in November 2015 and began intercepting his phone calls the following January before he was arrested in August 2016.
His trial is scheduled to continue on Tuesday.
