Passenger Movement Charge

The passenger movement charge (PMC) is an Australian tax payable by passengers departing Australia on international flights or sea transport, whether or not the passenger intends to return to Australia. The PMC was introduced in July 1995 (replacing the previous departure tax which commenced in October 1978) and was initially described as a charge to partially offset the cost to government of the provision of passenger facilitation at airports, principally customs, immigration and quarantine functions.
