Leaders from Sydney's synagogues and Jewish schools appeared before the Royal Commission on Tuesday to address the growing threat of antisemitism and its impact on social cohesion.

The testimony comes in the wake of the Bondi attack, with witnesses highlighting specific warning signs that Holocaust survivors and community members recognize from historical patterns of unchecked hostility.

The Royal Commission has placed significant focus on the online environment as a driver of the violence.

Previous evidence presented to the inquiry included testimony from a victim who described social media platforms as a 'cesspool of Jew hatred,' underscoring the digital dimension of the crisis facing the community.

Community advocates have raised concerns about the long-term viability of Australia's Jewish population if current trends persist.

The hearings aim to provide a comprehensive overview of the challenges, linking the specific incident in Bondi to broader societal fractures and the need for robust protective measures.
