Police in Far North Queensland are seeking help from the public after ten packages of a white powder suspected to be cocaine washed up at Hinchinbrook Island.
The packages, weighing about a kilogram each, were discovered by members of the public at the high tide mark in Ramsay Bay on Sunday.
Investigators from the region's Major and Organised Crime Squad are now searching the area.
Detective Acting Senior Sergeant Graham Camp said police want to speak to anyone else who has been in the area.
“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,” he said.
“It is possible further packages may wash up along the coast due to tidal flows and ocean currents.
“We urge the public to contact police should they find further packages and to not open them as the substance could be hazardous.”
The powder is still being forensically tested, but police suspect it is cocaine.
