A Sydney man accused of raping a schoolboy outside his family home after meeting him on a gay dating app is to continue being on bail.

Moud Nuri, 40, faced a charge of sexual intercourse without consent when he fronted Penrith Court.

Police have alleged Mr Nuri met the boy on Grindr where they exchanged photos, messages, personal details and then planned to meet.

But when the 13-year-old deleted the app and stopped contact, it is alleged Mr Nuri drove to his home on the afternoon of September 28.

Mr Nuri, who works as an IT project manager, is accused of pushing the boy to the ground in his front yard and sexually assaulting him.

The teenager's mother heard screaming and ran outside to help her son before Mr Nuri got into his car and drove away.

The alleged victim was taken to the Children's Hospital at Westmead where he was examined and treated for shock.

Two days later, Mr Nuri was arrested at his Kellyville Ridge home before he was charged at Riverstone Police Station in north west Sydney.

Mr Nuri ignored a pack of reporters when he left Penrith Court and he is due to face Blacktown Court later this year.

NSW police have now issued a warning to parents about online safety at a time when young children are on school holidays.

They want parents to speak to their kids about the dangers of talking to people online and to monitor their use of phones and tablets.

Households are also being advised to install computer blocking software and to be aware of how much time a child spends on the internet.

Grindr has been contacted for comment.
