Martin Thomas Glynn, 39, appeared in Fremantle Magistrates Court after officers from the State Security Investigation Group searched his Yangebup property earlier this week as part of Operation Dalewood.
The operation was launched following the Bondi terror attack, which killed 15 people and is considered the deadliest terrorist incident in Australian history.
Prosecutors told the court police located six registered rifles, approximately 4,000 rounds of ammunition, a flick knife, and three extremist flags, including those linked to Hezbollah and Hamas. Officers also allegedly seized a handwritten notebook containing anti-Semitic material and references to Adolf Hitler, reports The Nightly.
The notebook, labelled “ideology, views, insights and political ideas,” allegedly included references to the Holocaust and statements such as “Jews have always been scum ... we don’t want them near us or our family."
Police said a second search warrant was executed after officers found images on Glynn’s phone suggesting attempts to manufacture a smoke grenade and access information about making explosives. During that search, investigators allegedly found improvised initiators, shaved aluminium, pro-Hezbollah stickers, and a handwritten bomb-making shopping list.
Authorities also told the court Glynn had been flying a Palestinian flag outside his home, which police said caused concern among neighbors.
Glynn has been charged with conduct intended to racially harass, possession of a prohibited weapon, and failing to store firearms and related items correctly. Prosecutors alleged he posted messages to Instagram endorsing the Bondi massacre just hours after the attack on December 14.
“I just want to say, I, Marty Thomas Glynn, 100 per cent support the two New South Wales shooters RIGHT TO SELF DEFENCE AGAINST JEWS AND ALL FUTURE JEWS,” he allegedly wrote. In another post, Glynn added, “Delete me, unfriend me, don’t call me, I don’t care... if you actively support genocide in your religion, what the f... did (you) think would happen?”
Representing himself in court, Glynn said the flags and stickers were part of a collection of about 50 items and were not displayed. “They were packed away in a box,” he told the magistrate.
He described himself as a doomsday prepper and claimed the alleged bomb-making materials were fire starters used for a backyard fire pit. Glynn also said his notebook reflected his thoughts on the war in Gaza and ideas for a future business or political party.
Magistrate Benjamin Tyers denied bail, calling Glynn a danger to the community and citing the seriousness of the alleged offences, his onlin posts, and the quantity of weapons and ammunition found. Glynn was remanded in custody and is due to return to court on
