The court heard the pair met after first making contact last week on the dating website Plenty of Fish.
It is alleged the officer from the northern police region sexually assaulted the woman before grabbing her by the throat.
The police prosecutor, Sgt Scott Pearson, said the victim told him she did not want to be choked, to which the accused replied: “Shut up, cunt.”
He then allegedly told her she looked like the kind of girl who “liked to be choked in bed”.
The woman then dialled triple-zero, showed the man and threatened to call the police, the court heard.
It is alleged he then swore at her again before leaving.
The court also heard the man has no previous criminal history and has strong ties to the community.
There was no suggestion he used a weapon or caused significant injuries, his lawyer said.
His parents attended the court hearing.
He has been suspended since being arrested by members of the ethical standards command.
The magistrate, Tina Previtera, granted bail on the condition the man live with his parents and adjourned the matter until 16 May.
