A Vietnamese national has been charged after Queensland Police located more than $1 million worth of cannabis during a routine traffic stop overnight.

Officers from the Ipswich Tactical Crime Squad were carrying out patrols in Minden, 64 kilometres west of Brisbane, when they pulled over a Hyundai iLoad on the Warrego Highway about 7pm.

A search of the vehicle resulted in the alleged discovery of more than 250 kilograms of cannabis with an estimated street value of $1.5 million.

“It was a very large find for us, it was quite significant,” Queensland Police’s Glenn Fleming told 9news.

“There was a smell of cannabis emanating from the vehicle and as a result of that, police had cause to search the vehicle.”
