A Sydney man who claimed he was trying to prevent a terrorist attack has been found guilty of plotting to blow up an Etihad plane with a bomb hidden in a meat grinder.

Khaled Khayat, 51, had pleaded not guilty to conspiring - between January 20 and July 29 in 2017 - to do acts in preparation for, or planning of, a terrorist act.

However, a NSW Supreme Court jury on Wednesday found him guilty of the charge which involved the Etihad bomb plot and another plan to carry out a lethal poisonous gas attack on people in a confined space.
