NSW man jailed after designing missiles

A rural NSW electrician has been jailed for at least six years and nine months after he designed missiles for Islamic State

Haisem Zahab pleaded guilty in 2018 to knowingly providing support or resources to a terrorist organisation after working on a laser warning receiver, rockets and a rocket guidance method for IS from 2014.

The 44-year-old, from the NSW town of Young, also admitted he failed to comply with an order to help police access encrypted data on his phone and other devices.

On Friday, NSW Supreme Court Justice Geoffrey Bellew jailed Zahab for nine years with a non-parole period of six years and nine months.

The judge dismissed Zahab's claim he genuinely believed at the time of his offending that IS was "a force of good" rather than evil and could, therefore, assist civilians in Syria fight the regime of President Bashar al-Assad.

He rejected Zahab's testimony that he had been in a cult or bubble of IS supporters - including on Twitter where he assumed the alias "Stranger" - and had divorced himself from mainstream news.

Justice Bellew was also sceptical of the electrician's subsequent contrition.

With time already served, Zahab will be eligible for release in December 2023.
