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. Groups led by Abdul Nacer Benbrika and Khaled Cheikho were active in Melbourne and Sydney, respectively, until police arrested their members in 2005. Instances of domestic terror inspired by radical political Islam include the plots by Faheem Khalid Lodhi, Abdul Nacer Benbrika and Joseph T. Thomas.
