This former prison guard spent months in Goulburn jail after his ex-partner falsely alleged he had bashed and sexually assaulted her.

Prosecutors will press for full time jail for a woman who has admitted she made a false rape allegation against her former partner, a court heard on Tuesday.

The former NSW police worker, 28, pleaded guilty this week to the false accusation charge, admitting she staged a fake crime scene, self-inflicted injuries to her head, called triple-o, and later concocted a fake story to police.

Among the false allegations she made were that her ex-partner had come to the house and raped her before hosing her off in the yard, court documents say.

When the man was arrested on her false allegations he spent more than three months in Goulburn Supermax prison, because of his work as a Canberra prison guard.
