Australian police say they recovered thousands of rounds of ammunition, extremist flags, and materials linked to explosive-making during a search of a suburban home in Western Australia, after a man was charged over alleged antisemitic social media posts praising a deadly mass shooting.
The accused, Martin Thomas Glynn, 39, appeared in a Perth court on Wednesday facing three criminal charges, including possession of a prohibited weapon, according to court records and police statements.
Prosecutors allege Glynn made inflammatory social media posts on Dec. 14, just hours after two gunmen killed 15 people at Bondi Beach in Sydney during a Hanukkah celebration—an attack that authorities have described as the deadliest mass shooting in Australia in nearly 30 years.
In a statement of facts presented to the court, police said Glynn publicly expressed support for the attackers. One post allegedly quoted him as saying: “I just want to say that I, Martin Glynn, 100 per cent support the New South Wales shooters.”
Police told the court the posts raised immediate concern and prompted a rapid investigation.
Glynn was arrested on Tuesday after officers executed a search warrant at his home in a suburb of Perth, where investigators said they found six legally owned rifles, approximately 4,000 rounds of ammunition, and a handwritten list of items police described as materials commonly used to make explosives.
Authorities also said they seized flags associated with Hamas and Lebanon’s Hezbollah, both designated as terrorist organizations by Australia and several Western governments.
Police emphasized that while the firearms were lawfully acquired, the volume of ammunition and the presence of extremist material formed part of the broader case being examined by investigators.
Glynn’s arrest coincided with swift political action following the Bondi Beach attack. On the same day he was taken into custody, the New South Wales government announced proposed emergency reforms that would tighten gun ownership laws and allow authorities to temporarily ban street protests for up to three months.
State officials said the measures were aimed at restoring public confidence and preventing further violence as communities across Australia reeled from the attack.

Authorities have framed Glynn’s arrest as part of a broader effort to counter violent extremism and reassure the public amid heightened security concerns nationwide.
Glynn has not yet entered a plea, and the court did not hear arguments on the substance of the charges during Wednesday’s brief appearance. The matter has been adjourned, with further hearings expected as prosecutors continue to assemble evidence.
Police said the investigation remains active and that additional charges have not been ruled out.
