A search and rescue operation is underway at a popular Queensland waterfall after two swimmers failed to surface after taking the plunge at the popular tourist attraction.
Emergency services rushed to Millaa Millaa Falls, approximately 90km southwest of Cairns, around 8.55am on Tuesday after reports two men were missing.
Queensland Ambulance Service's far north director Chris Draper said three men in their 20s had jumped from the falls into the water but two had not surfaced.
A spokesperson for Queensland Police said a third male has been taken to hospital.Â
Mr Draper said there are roads into the waterfall for emergency crews to use for the search operation but accessibility was difficult for rescue helicopters.
