The wife of a terrorist recruiter has been spared jail and will instead serve 75 hours of community service for refusing to stand for a judge in court.

In Downing Centre Local Court on Wednesday, Moutia Elzahed, 50, became first person in NSW to be sentenced for the offence.

Elzahed, who is married to jailed Islamic State extremist Hamdi Alqudsi, was in May found guilty of nine counts of disrespectful behaviour in court.

In that hearing, Elzahed remained seated with her arms crossed as magistrate Carolyn Huntsman delivered the landmark decision.

Elzahed then gave the IS salute outside Sydney's Downing Centre Local Court while her friend called journalists "cockroaches".

The stand-off came to a head when the magistrate returned to the bench and ordered Elzahed to leave her seat at the back of the courtroom and approach the bar table.

"Remain standing - you remain standing when I speak to you," Ms Huntsman said.
