SES crews have described the dangerous operation rescue crews embarked on after two people were rescued from treacherous caves west of Sydney.
Emergency services were called to the Jenolan Caves off Jenolan Caves around 7.20pm yesterday after multiple people became trapped in a narrow passage for several hours.
Police said a man and a woman, who had been exploring the caves as part of a group, both became trapped.

The pair were part of a larger adventure group from Canberra that were able to exit the cave and raise the alarm.
The almost ten-hour rescue of the pair unfolded at the cave site, which lies more than 100 kilometres west of Sydney in the Blue Mountains.
A large number of resources responded, including the NSW Police rescue unit, the SES and multiple ambulance crews.
Emergency crews waited outside the caves while specialists drilled into the rocks to carve out a path for the man and the woman, who were able to leave the cave just before 5am today.

Oberon SES member Craig Gibbons was one of seven SES members who assisted in the rescue.
He said cave rescues were a complex operation and described the Jenolan caves as "more dangerous".
"The man was stuck in a tight and narrow spot in the cave, with a woman behind him," he said.
"We entered the cave from the other side, and needed to drill small holes and chisel some of the rock wall away so we were able to free the trapped man.
"Once we got the man free, we handed him and the female over to paramedics, and it was great to see them both walk away from the scene safe and well despite it taking many hours to get him free.
"This was my first rescue in the adventure caves – which are more dangerous as they're in much tighter areas that are difficult to access."

Gibbons has been a member of the NSW SES 30 years and has conducted a number of rescues at the caves over the years.
"About a dozen or so have been in areas known as show caves, which are more accessible," he said.
"We do a lot of training to build our skills, and it was just great to get a successful outcome today."
The pair were assessed by paramedics and there were no reports of any injuries.
