A British man accused of a "horrific" sexual attack on a woman and allegedly knocked out her male friend in the NSW Snowy Mountains works at a ski resort and is on a temporary work visa, police say.
The 28-year-old was arrested at a home on Tuesday in Jindabyne near where the attack took place last week.
It's alleged a 22-year-old woman and a 25-year-old man were walking along the town's main road when they approached by a man who punched the male unconscious and then physically and sexually assaulted the female.
The pair from NSW were treated by paramedics for facial injuries before being taken to hospital.
"It's a fairy horrendous attack for us just hearing about it, let alone having to experience it," Detective Acting Superintendent Tom Barnes told reporters in Sydney.
"The victims are recovering as well as can be expected from their physical injuries but clearly they have a long way to go in terms of the psychological impact it's no doubt having."
Investigators believe the man, who works as a resort ski instructor, acted alone and are working to charge him later on Tuesday.
Det Supt Barnes said the man had spent a short period of time in Australia on seasonal work.
