they have delivered publicly to the Muslim community or have otherwise shared with others in public settings. In some instances, various ideas and viewpoints espoused by these preachers have been subject of public or internal debate. Statements viewed as misogynistic and radically paternalistic have come under criticism. Islamist extremism A number of incidents have highlighted the issues associated with Islamist extremism in Australia, including terrorism and militant activity. Several foreign terrorist organisations have sponsored the establishment of cells in Australia, including Lashkar-e-Taiba, and Jemaah Islamiah. Al-Shabaab is believed to have been behind the Holsworthy Barracks terror plot. A man known as "Ahmed Y" established a small militant group in Australia in 2001 and advocated the idea of establishing an Islamic State in Australia.
