AT LEAST $6 million worth of the drug "ice" has been destroyed and three people arrested following a major investigation into a national crime syndicate.
Police believe the 6kg haul of methamphetamine discovered at a property in western Sydney last week was destined for supply to dealers in NSW and parts of Queensland.
A man and woman, both aged 31, are currently before the courts on commercial drug supply charges.
A third man, aged 29, was arrested late Thursday and charged over his alleged involvement.
Police expect to make further arrests.
