Paula Denyer (born Paul Charles Denyer, 14 April 1972) is an Australian serial killer currently serving three consecutive sentences of life imprisonment with a non-parole period of 30 years for the murders of three young women in Melbourne, in 1993.
Denyer became known in the media as the Frankston Serial Killer as her crimes occurred in the neighbouring suburbs of Frankston.
Later, during her imprisonment, when aged around 30, Denyer began identifying as a transgender woman, but was refused permission by prison authorities to wear make-up, receive sex reassignment surgery, or legally alter her name.
