Several injured in bus crash at Perisher Valley in NSW Snowy Mountains

Seven people have been treated for injuries after a bus with dozens of adults and children on board crashed at Perisher Valley in the NSW Snowy Mountains, emergency services say.

Multiple ambulances rushed to Kosciuszko Road, near Guthega Road, following the crash just before 5.30pm today.

Police were told the bus, carrying about 40 adults and children, had gone down a small embankment on the side of the road.

No one was trapped but some people were injured, police said.

A NSW Ambulance spokesperson said there were seven patients — including four children — revised down from eight earlier in the evening, all with minor injuries.

Paramedics assessed two other children but they didn't need to be taken to hospital.

"This would have been a really scary experience for everyone involved, especially the children, but  everyone kept calm while we assessed and treated those who were injured," NSW Ambulance Inspector Jennifer Barker said.
