ONE woman could never return to her home after a man broke in and, without saying a word, raped her.

Another victim of Jeffrey Allan Morris asked her family to move into a smaller house, where she could see every corner of the room because she was so scared.

Morris, 54, pleaded guilty to two counts of sexual intercourse without consent and other charges, related to his breaking into the homes of two women, raping them and stealing from them in 1988 and 1990.

In the Downing District Court on Thursday, Judge Peter Berman sentenced Morris to at least five-and-a-half years' jail, with a maximum sentence of eight years.

On the morning of September 15, 1988, Morris broke into the Ultimo home of a woman, who was asleep after working night shift, Judge Berman said.

"She was woken up by noise from downstairs. The offender went into her bedroom without a word," he said.

"The offender walked to her and punched her in the face, splitting her lower lip.

"Not surprisingly, she was petrified and did not move."

Judge Berman said the woman was afraid she had contracted HIV from the rape, and had to wait three months to find out she did not have it.

"Any young woman assaulted in the way I've described in the sanctity of her own home would be significantly affected by the experience.

"[She] never returned to her house and had to give up her job."

Less than two years later, on February 17, 1990, Morris knocked on the door of a house in Artarmon asking to see someone. The teenage girl who opened the door told him she did not know of anyone by that name.

He then returned to the house, knocked on the door and pushed the girl to the ground.

"He grabbed her and walked her towards the lounge room saying 'I've got a knife'.

"He pointed something metallic into her side."

In a victim impact statement read to the court on the 1990 victim's behalf, she said the effects had been lifelong.

She insisted her family moved into a small place so she could see "every corner of the house because I was afraid of what or who could have been hiding in the room".

The woman said she had lost her self-esteem and could not fulfil her dreams of studying and working.

"I married the first person that would have me, not thinking if he was the right one for me or if I loved him enough, because I thought no one else would have me.

"And having children, I've been constantly scared for them."

Judge Berman said Morris, who was arrested in 2011 after DNA evidence linked him to the victims, had caused "enormous harm" to both women.

"It's not an exaggeration to say that they were violated by a complete stranger who thought nothing about [their] wellbeing."

Morris will be eligible for parole in January 2017.
