A man has been charged following the stabbing of three international tourists outside a backpacker hostel in Sydney’s CBD.

The 36-year-old man will face court after the tourists were attacked with a piece of broken glass at the Nomads Westend Backpackers in Haymarket early on Thursday morning.

Police were called to the Pitt Street hostel about 2.15am and arrived to find two men, both aged 19 and German nationals, and a 24-year-old Irish woman suffering from stab wounds.

They told police they had been confronted by a man who was believed to have emerged from a neighbouring halfway house.
