Omar Al-Kutobi and Mohammad Kiad pleaded guilty to doing acts in preparation for a terrorist act targeting a Shia mosque in Sydney’s west at Guildford.
They were arrested during a police raid days after they had purchased a large hunting knife from a military supply store.
The two men planned to bomb the prayer hall with homemade napalm and vowed to stab people in the kidneys to impress an Islamic State recruiter before they were jailed in 2016.
They were sentenced to 20 years’ imprisonment with a non-parole period of 15 years.
The NSW Court of Criminal Appeal on Monday quashed those sentences, imposing a new sentence of 16 years with a non-parole period of 12 years.
