A 33-year-old man, reported to be from Roxburgh Park, has been remanded in custody after being charged for allegedly smuggling 5 kilograms of cocaine through Melbourne International Airport. 

The man, who appeared at the Melbourne Magistrates Court on Saturday, had arrived on a flight from Dubai on Friday night.

The Australian Border Force officers examined the man's suitcase at the airport and allegedly found it had a false bottom which, when removed, revealed three packages wrapped in brown packing tape.

ABF officers said the packages contained cocaine weighing approximately 5kg. A further forensic test will determine the exact weight and purity of the substance. 

The man is due to reappear in the Melbourne Magistrates Court on Wednesday to face charges of importing and possessing a commercial quantity of a border controlled drug.

The maximum penalty for these offences is life imprisonment.
