A CONTROVERSIAL Islamic preacher charged with child pornography offences and threatening a terrorist attack on Sydney's Mardi Gras parade has been granted bail in a Sydney court.

Ibrahim Siddiq-Conlon, 35, is accused of making a hoax terrorist threat on the Facebook page of Today FM's Kyle and Jackie O Show.

He allegedly outlined a "terrorist threat" to the annual Sydney parade that celebrates gay lifestyles and diversity, in a post on the show's online chat forum.

Siddiq-Conlon is also facing two separate charges relating to use of a laptop to access online child pornography and a charge of possessing child abuse material.

In granting bail in the NSW Supreme Court on Tuesday, Justice Geoff Bellew banned Siddiq-Conlon from using the internet and possessing a phone with internet capabilities.

He also made it a condition that the preacher not enter any international point of departure from Australia or apply for a new passport.

Justice Bellew also imposed a strict night curfew and daily police reporting regime on Siddiq-Conlon, who will live with his mother in Cowra while out on bail.

The preacher is forbidden from being in the presence of any children under 18, except for his own, and banned from going anywhere near schools, daycare centres or preschools.

The court heard that Siddiq-Conlon had already breached earlier bail conditions by using the internet to contact his wife and children in Indonesia and downloading legal files and documents related to his work as an architect.

Justice Bellew said given the previous breach he was surprised prosecutor Jody Nunn was not opposing bail on this occasion, but he said he was "loath to interfere" with the crown's decision.

Siddiq-Conlon founded Sharia4Australia in Sydney's southwest to agitate for Islamic law and the introduction of sharia courts.

The preacher, from Lakemba, is due back in Sydney Central Local Court on July 25.
