Pseudoephedrine found in parcels at Sydney mail centre

CUSTOMS officials have nabbed about 15kg of key ingredients used in the production of potent street drugs at three NSW border checkpoints.

About 5.9kg of pseudoephedrine and 2.5kg ephedrine were found stashed in a variety of parcels at the Sydney International Mail Centre earlier this week.

The precursors are commonly used to make methamphetamine like ice.

At Sydney's International Airport, a 46-year-old woman was arrested after 2.6kg of ephedrine was allegedly found in a number of food packages she was carrying in her bags.

In a separate incident 4kg of ContacNT, a cold a flu medication containing high amounts of pseudoephedrine, was discovered during a search of an air cargo consignment of power tools from Hong Kong.

Customs and Border Protection Direct of Investigations for NSW Tony McSweeney said the discoveries demonstrated how officials detect drugs and precursors despite the wide variety of concealment methods.

Suspicious behaviour relating to border protection can be reported to Customs Watch on 1800 061 800 or at the Customs Watch website.
