Two men still missing in Qld after cyclone

Two Queensland men who went missing amid wild weather and flooding brought on by Cyclone Debbie still haven't been found.

The search continues for a 65-year-old man missing in Lamington National Park, as well as 58-year-old John Frost from Mount Pleasant in Mackay.

The body of 50-year-old David Heidemann was found by emergency services workers over the weekend at Barambah Creek, northwest of Gympie.

He had been last seen on March 30 leaving an address on Mondure Wheatlands Rd, telling family he was meeting a friend on Campbells Rd.

A report is being prepared for the coroner.

Police have said they were still trying to determine the cause of death, but believed he had fallen victim to flooding in the area.

It came after the body of 77-year-old Nelson Raebel was found in floodwaters in southeast Queensland at the start of the month.
