The children of missing Queensland man Alex Rosenberg have arrived in Katherine appealing for public help.
Mr Rosenberg’s son and daughter arrived yesterday and have asked anyone with any information about their father’s disappearance to help police.
Mr Rosenberg went missing from the Edith Falls campground on the weekend.
New information suggests he was seen in the campground on Sunday and did not go missing on the Saturday, when he initially arrived, as first thought.
An extensive search by air, ground and water has still failed to locate the 67-year-old.
Yesterday 10 police and 25 NT rangers continued the search using line searches of the surrounds and by helicopter.
Five police divers searched the Edith Falls plunge pool which was closed to the public.
The search of the deep pool and the other upper pools is expected to take several days.
The missing man’s son and daughter arrived yesterday and were briefed on the search by police.
The family is appealing for anyone with information or having sighted their father to please contact Crimestoppers on 1800 333 000, or police on 131 444.
