Border Security: Australia's Front Line

Episode 4 (14x4)

:

A father and son duo are returning from a holiday in Thailand. Officers discover the men have had trouble crossing borders in the past when the father openly admits he was once caught with ten Tasers. He's also packed something illegal before this flight. But that's not all officers find, when a swab test comes back positive for traces of heroin. Flights are arriving in the Top End, carrying passengers attending a music festival, so the Customs drug dogs are out in force. Then, a package containing pool toys arrives from Argentina and raises suspicions when officers discover a hidden substance.
