Police seize cash, ice from car in Grafton

More than $500,000 worth of methylamphetamine (ice) and cash has been seized from a car after the driver was allegedly caught speeding on a northern NSW highway.

Highway patrol police found the cache during a search of a Toyota Camry that was stopped when it was allegedly clocked driving at 158km/h in a 100km/h zone on the Pacific Highway south of Grafton.

"A vehicle search was then conducted during which police will allege they found $290,000 cash and methylamphetamine (ice) with an estimated potential street value of $218,000," police said.

The men from Hong Kong, 29 and 27, have been charged with supplying an indictable quantity of a prohibited drug and knowingly deal with the proceeds of crime.

Bail was refused and they're due before Grafton Local Court on Monday.
