A West Papuan refugee has been jailed for at least four years after he attacked a sleeping Melbourne woman in her home.

A refugee who broke into a Melbourne woman’s home and raped her has been jailed for at least four years.

Alfons Pirimapun, 34, bent a flyscreen and climbed into the woman’s bedroom as she slept in November 2012.

He began sexually assaulting her before she woke up and began screaming, and he was eventually chased from the Fitzroy home by her housemates.

When arrested, Pirimapun told police he had been drinking in a nearby park and had stood outside his victim’s window for around 20 minutes.

Pirimapun, who fled West Papua in 2006, has previously been jailed in Queensland for indecently assaulting women in similar circumstances.

Victorian County Court Judge Susan Cohen told Pirimapun he had committed a serious invasion of his victim’s privacy.

“You breached the security of her own home, her sleep,” she said.

She sentenced Pirimapun, of Collingwood, to six years in jail with a minimum of four years on charges of aggravated burglary, indecent assault, rape and theft.

He was put on the sex offenders register for life.

During a pre-sentence hearing last year, Pirimapun’s lawyers said he feared being deported once his prison sentence expires.

But Judge Cohen said she could not take his likely deportation into account in setting the sentence.
