Dozens of Melbourne airport staff are accused of collaborating with organized crime groups to smuggle drugs into Australia.

Some airline crew members were found consuming drugs while on duty.

Border Force investigations revealed attempts to bypass security measures and hide contraband in double-bottom suitcases.

A total of 70 employees breached security checks, leading to visa cancellations for two international crew members found under the influence of illegal substances.

The investigation is led by Border Force superintendent Kelly-Anne Parish and focuses on individuals in aviation with alleged ties to transnational organized crime groups.

Portable X-ray machines were deployed to ensure the safety of the aviation supply chain by scanning baggage storage, cargo holds, and crew areas.
