Four charged over another huge methamphetamine haul

Australian Border Force officers found the drugs in June during a search of a consignment sent from the United States. 

AFP Commander Raegan Stewart is expected to share more detail on the bust on Monday morning. 

It follows a near $1 billion methamphetamine shipment seized from two large machines a shipping container at Sydney's Port Botany in July.

That shipment was also sourced from the United States before authorities removed the drugs and delivered the machines to a premises at Warwick Farm, in the city's west, leading to the arrest of two men.
