## Summary

A 16-year-old who pleaded guilty to planning a terrorist attack in Sydney in 2024 avoided jail, with the New South Wales Supreme Court ordering a three-year community corrections order. He told the court he was radicalised online after first seeing extremist material on TikTok, and used ChatGPT to research security at the Sydney Opera House. OpenAI, Telegram and YouTube were approached for comment; TikTok declined.
