Beachgoers reported to police after discovering two separate one-kilogram packages, containing a powder substance on Bundaberg beaches at Elliott Heads on December 21 and Mon Repos on December 27.

Police are awaiting forensic examination results of the powder.

Superintendent Craig Hawkins of the Wide Bay Burnett District said police were worried the contents of the packages could become a health risk.

He said police believe there could be other packages that might wash up along the coast due to tidal flows and ocean currents and found the packages suspicious and concerning.

Superintendent Hawkins said he was urging anyone with information or had found further packages to contact police and to avoid opening them as the substance could be hazardous.

“Any further information we can get from the public may help us establish the locations of further packages,” he said.

“Anyone who was at sea or on the coastline near these locations and saw anything suspicious in the water or other suspicious activity is urged to contact police."
