Inbound duty free: For flights to Australia, all LAGs will be restricted to 100ml containers contained within in a one litre bag. Duty free items may enter the country ONLY if they are delivered to the gate in a sealed bag with proof of purchase and only collected by the passenger after proceeding through LAGs screening at the last port of departure. Singapore is introducing gate delivery for Australian flights, for example. No LAGs outside the 1 litre bag can transit through Australia.
Outbound duty free: Passengers may take all LAGs purchased or collected in the sterile area of an Australian international airport on board an aircraft, including duty free items, unless other jurisdictional measures apply.
Acceptable / Harmonised Countries:The Australian Government has said it will have a list of States that have acceptable gate delivery in place for flights to Australia. New Zealand is the one country that currently has an agreement with Australia to allow inbound passengers to purchase travel retail items without gate delivery.
