Former Australian Treasurer Josh Frydenberg has attributed the nation's worst terrorist attack to a combination of Islamic extremism, government inaction, and insufficient security screening for migrants from Middle Eastern regions. In interviews, Frydenberg criticized the government's focus on tightening gun laws, arguing that it overlooks the underlying ideology and years of ignored extremism and rising antisemitism. He highlighted the vulnerability of Jewish Australians, citing recent harassment, violence, and intimidation, and called for stronger action against hate groups and incitement. Frydenberg emphasized that the issue transcends politics and urged the government to take more decisive measures to ensure safety and restore Australia's sense of security.
