The main Edith Falls plunge pool has been closed to the public as divers search for missing Queensland man.
It is now five nights since 67-year-old Alex Rosenberg of Queensland went missing from the camping grounds.
The aerial search resumed as well today with helicopters continuing their search in a widening circle around the camp grounds.
NT Police and Parks Rangers are also still conducting line searches at Edith Falls for the missing man.
Great fears are held for the safety of the 67-year-old man from Queensland who has not been heard of since Saturday night.
He set up his camping equipment in the evening, booked for a two night stay there and has not been seen since.
The alarm was raised on his disappearance on Tuesday.
According to police, his vehicle and camp were left as though he intended to return in a short time.
About 30 police and Parks Rangers took to the ground, again scouring the car park and surrounding area.
Temperatures have been rising to above 33 degrees during the day and below 10 degrees during the nights since his disappearance.
Acting Superintendent of the Katherine Division Mark Malogorski said a systematic search involving NT Police, NT Parks and Wildlife Jawoyn Rangers and Northern Territory Emergency Services has been ongoing since Tuesday morning.
“The search area covers approximately 40 square kilometres,” A/Supt Malogorski said.
“The response and support from other agencies has been outstanding, with rangers being brought in from as far away as Timber Creek, Darwin and Mataranka.
“In addition, two helicopters are being utilised in the search as well as a specialist Police Dive Team conducting underwater operations in support of the search.”
“So far search personnel on foot have scoured over 70km of ground in extremely rugged and unforgiving country in hot conditions and aircraft have flown over 500km conducting aerial search tasks.”
Police now hold grave fears for the safety of the missing man and will continue search efforts today.”
