A man who bashed his own grandmother before attacking and repeatedly raping his teenage half-sister has been sentenced to six and a half years’ prison.
The 25-year-old – who cannot be named to protect the victims’ identities – was jailed on Tuesday after details of his 30-minute violent rampage in July were laid bare in the District Court of Western Australia.
Court heard the attack began at his grandmother’s house, in Perth’s south-east, after the man consumed alcohol and cannabis earlier in the day, WA Today reported.
He was weighing himself in the bathroom with his grandmother, aged in her 70s, when he turned on her by grabbing her by the neck and hurling her towards the floor.

She was then punched in the head and face between six to 12 times and also kicked, court heard.
Leaving his grandmother savagely beaten on the bathroom floor, he then went to his half-sister’s bedroom and began punching her repeatedly before smashing her over the head with a teacup.
The woman, aged in her late teens, was then dragged to the front of the house where she was repeatedly sexually assaulted.
Court heard the man excessively watched violent pornography in the years prior to the attack.
Both victims were told they would be killed if they didn’t do what the man said.
He then drove off in his grandfather’s car and threw his half-sister’s phone out the window.
Both victims were taken to hospital with horrific injuries, while the man was arrested and confessed to the acts later the same day.
Prosecutor Sarah Jessup told the court the man went to his grandmother’s with the intention of ‘losing it’.
Court also heard the man’s offending appeared to be linked to the consumption of alcohol and cannabis earlier in the day.
The man pleaded guilty to nine charges, including one count of aggravated grievous bodily harm and six counts of aggravated sexual penetration.
Judge Christopher Stevenson said the offences were ‘extremely serious’, involving attacks on people ‘very close’ to the man.
He added: ‘At the same time as physically punching and kicking the victims, you also threatened to kill them. The conduct was obviously degrading to both of them and unexplainable.
‘The impact of the offending on each of the victims cannot be overstated.’
He will be eligible for parole after serving four and a half years.
