Update at 5.20pm: The search operation has been called off after inquiries concluded that initial reports about people missing were miscommunicated, Riverina police Acting Inspector Ged Horsley said.
"Nobody was lost," he said.
"It's a bit of a nuisance, we had one police officer walk all the way up to the top and back again.
"We had two crews but it was better to make sure no one was lost."
Acting Inspector Horsley said crew members from all emergency units have been stood down about two hours after the initial reports.

"But until we know for certain, we can't confirm."
