A British ski instructor who laughed as he raped a woman after brutally beating her partner has been jailed for 10 years in Australia.

Matthew Williams, 29, attacked the couple in July last year as they were walking back from a pub in Jindabyne at 1am in the New South Wales Snowy Mountains.

After taking MDMA and drinking with family and friends at the Banjo Paterson Inn, the pair walked up Jindabyne’s main street, Kosciuszko Road.

Williams, who had also been drinking at the inn, followed them up the street for one kilometre before punching the man shortly after asking him “how’s it going mate?”, according to accounts given to the police.

After the 25-year-old man fell to the ground, Williams kicked him and he lost consciousness.

He then punched the woman to the ground and laughed at her while she tried to fight him off, knocking her out, New South Wales district court was told.

She woke up with Williams pinning her to the ground and struggled to get free as he once again punched her before removing her clothes.

The woman struggled to free herself as Williams bit her breast while ripping off her clothing.

The ordeal only ended when the partner woke up and managed to get away from Williams, and flagged down a passing car, causing Williams to run off.
