HK man charged over undeclared $A300,000

A Hong Kong national has been charged after attempting to leave Australia with $300,000 in undeclared cash he had stashed in his luggage.

The 31-year-old man was picked up at Melbourne's International Airport after customs officers found the money on Tuesday.

The officers also retrieved the man's customs declaration, which confirmed he had not declared he was exporting excess currency.

Federal police stopped the man leaving Australia on a Hong Kong-bound flight.

After his arrest, he faced charges of money-laundering and dealing with money suspected of being the proceeds of crime.

He is expected to appear in Melbourne Magistrates Court at a later date.

Victorian regional commander Graham Krisohos of the Australian Customs and Border Protection Service said there was no limit to the amount of currency that could be brought in or out of Australia.

However, "if you have more than $10,000 of currency, you must declare it to a Customs and Border Protection officer before you enter or leave the country", Mr Krisohos said.
