Rescue teams in Nepal are racing to free more than 930 workers believed to be trapped underground in at least six different hydropower projects destroyed in last week's devastating flash floods.

Professor Arnold Dix, an Australian engineer and tunnelling expert, is helping Nepali authorities in their bid to find the trapped workers.

He spoke with SBS World News presenter Janice Petersen about the immense challenges of the operation.
