NSW Police attended a home in Oran Park in Sydney's south-west around 11.30pm Sunday night after a witness reported the alleged assault of a 21-year-old woman.

They charged a 26-year-old man with common assault and served him with an apprehended violence order.

Video of the incident was streamed from the account of MrDeadMoth and shared online on Sunday night.

In it, a woman off camera asks him to leave the computer because he is missing dinner.

"I'll be out soon," he replied.

A cardboard box and other items appear to be thrown at him from across the camera.

"Can you not," the man says.

The man leaves his desk before a slapping noise is heard off camera and a woman is heard crying.

"You're a f***ing woman basher," she sobs, before her voice addresses those watching the livestream.

"You hear that, all you people there, he just hit me in the face."

The man then tried to continue playing the game but she demands that he stop.

"F*** off you dog, you don't pay the f***ing bills," he says before disappearing off camera again.

A thudding noise can be heard before a woman is heard loudly wailing.

"Go away stop touching my f***ing shit," he yells.

"Get out of my f***ing life."

While he is sitting down it sounds as though something is thrown at him, and he rushes off camera again.

Shortly afterwards a woman is heard screaming again, and a child is heard shouting in the background.

Police said two girls, aged three and 20 months, were home at the time.

They said the woman was not seriously injured but was "distressed and shaken" by the incident.

The man has been granted conditional bail and will appear at Camden local court on Thursday.
