About 50kg of the drug ice has been found hidden in a container load of toilets imported into Melbourne.

Customs officials X-rayed the load of porcelain toilets, shipped from China, on July 25.

They found 17 packages containing drugs with a street value of $50 million.

The toilets were tracked to a suburban home, and a 33-year-old Kings Park man was arrested on Thursday.

The man has been charged with importing a commercial quantity of a controlled substance and he is due to appear in Melbourne Magistrates Court on Friday.

The drugs were seized in a joint operation involving Australian Federal Police, the Australian Crime Commission, Customs and Victoria Police.

It is the second major seizure of ice in Melbourne this week.

Suitcases containing 135kg of the drug, with a street value of $130 million, were seized by police in a Melbourne apartment on Tuesday.

Victoria Police Assistant Commissioner Stephen Fontana said the seizures were the result of expanding multi-agency collaborations targeting organised crime.

“There’s always a syndicate behind it, particularly where you see products coming from other countries,” Mr Fontana told reporters in Melbourne.

“I’m sure they won’t be happy about losing their product – that’s profit that they have lost but they will probably be determined to keep moving on.

“We’ve got a glut of drugs out there, that’s the reality … but we’re not going to give up on it.”
