The Australian navy has seized two tonnes of illegal drugs in the Middle East worth about $100 million in street value.
HMAS Ballarat found the hashish - a drug made from cannabis - in 100 hessian bags during a boarding operation on February 28 in international waters in the Arabian Sea.
"The ship as a whole is very proud of our achievements to disrupt the trafficking of drugs and promote a safer maritime environment," Boarding Officer Lieutenant Lachlan Turner said in a statement on Sunday.
This is the sixth seizure of narcotics by the vessel in the Middle East since departing Western Australia in October.
The operation is Australia's contribution to the Combined Maritime Forces in the Middle East region involving 33 navy partnerships to promote maritime security in the region.
HMAS Ballarat has previously seized about 1.2 tonnes of heroin and 5.2 tonnes of hashish.
