A Granville man who died in Syria with his wife was allegedly recruited to the battlefield by a radical disability pensioner living in the western suburbs, the Sydney Morning Herald reported.
Yusuf Ali was one of six men allegedly sent to the frontline by Hamdi Alqudsi, 39, to fight with terrorist organisations in the country's civil war.
Mr Alqudsi, from St Helen's Park, was charged in December with recruiting, funding and organising for the men to travel to Syria to fight with Jabhat al-Nusra and other al-Qaeda affiliates.
It is believed Mr Ali and his wife, Amira, 22, were killed by the Free Syrian Army after being caught in factional fighting.
Federal police fear there are more networks operating, fuelling a constant flow of Australians going to Syria.
