SYDNEY -- Australian police have seized 558 kilograms (1,230 pounds) of crystal methamphetamine and heroin with a street value of up to 500 million Australian dollars ($525 million) smuggled into the country in a shipment of terracotta pots.

Australian Federal Police say four Hong Kong nationals and three Australians were arrested in Sydney on Monday. Each faces a potential life sentence if convicted on drug charges.

Police said Tuesday that the 306 kilograms (675 pounds) of crystal meth – or ice – is the largest seizure of the drug in Australia. The 252 kilograms (556 pounds) of heroin is the third-largest haul of its kind.

The U.S. Drug Enforcement Administration alerted Australian authorities to the plot last August. Police will not say where the drugs came from.
