A Malaysian man has been arrested and is facing life in prison over what's been described as the largest heroin haul in Australia's history.
The Australian Federal Police and Australian Border Force (ABF) said more than 450kg of the illicit drug, worth A$140m ($147m), was found hidden inside a container of ceramic tiles sent from Malaysia to a Melbourne business.
The shipment arrived at the Port of Melbourne on September 29.
ABF officers examined the container and found packages with distinctive red heroin branding, which later tested positive.
It's estimated the total of 1290 packages weighed 451kg, making it the largest onshore detection of heroin in Australia. Investigators on Friday searched businesses and residential properties across Melbourne.
