A 16-year-old boy has been sentenced to a seven-year term of detention for raping a young woman at knifepoint during a "shocking and appalling" home invasion in South Fremantle.
Children's Court president Judge Denis Reynolds said this afternoon there was a strong need for the sentence to send the "loud and clear" message that vulnerable people in their own homes needed to be protected.
The teenager, who can not be identified for legal reasons, will serve three and half years in detention before becoming legible for supervised release just shy of his 20th birthday.
The boy was sentenced after pleading guilty to two counts of aggravated sexual penetration, one count of aggravated burglary and one count of creating a false belief.
Earlier today, Judge Reynolds was told that the teenager had fabricated elaborate stories that he had been sexually assault himself by two Aboriginal men on the night of the home invasion on September 27 last year and then forced to rape the woman in her home.
He then changed his story, claiming to have been threatened by members of the Comancheros bikie gang who were chasing a drug debt.
Both stories were shown to be "nonsense", but still needed to be investigated by police.
The court was told the boy entered the South Fremantle home of the 23-year-old university student about 1.30am. He removed his shoes, trousers and underwear and armed with a knife, told the woman he was going to “f…” her and would kill her if she screamed.
She eventually fled the house screaming, naked from the waist down.
The teenager inadvertently recorded his break-in through an open window while using his light on his mobile phone during the home invasion, revealing he spent about 10 minutes the lounge room and re-arranged items before sexually assaulting the woman.
The footage, as well as audio of him crying during a conversation with his brother from detention and maintaining his elaborate explanation of being raped, was played to the court.
The teenager was born in South Africa before his family moved to the United Kingdom when he five and had since relocated to Australia.
His mother, an alcoholic, died from liver failure when he was 10.
Prosecutor Sean Stocks described the boy’s offending as calculated, callous and cowardly, saying the teenager had no remorse, shame or concept of the effects of his behaviour for his victim.
Mr Stocks said the once social woman now despised being approached by strangers and felt guilty for the financial and emotional support she needed from her boyfriend and family.
"At the age of 23 I have survived the most traumatic experience of my life,” the woman said in a victim impact statement read to the court.
"I was convinced I would die a violent, lonely death. I was in terror.”
Judge Reynolds said the community, in particular women! had to be protected from violent sexual behaviour and were entitled to feel safe in their own homes.
He said the young man did not feel anywhere near enough remorse and only a lengthy sentence of detention was appropriate.
