I am flying with Qantas Airways from Melbourne to Sydney with a 1.5 hour layover before continuing to Tokyo via Haneda Airport.
I am trying to understand how the international departure process works for this itinerary. Specifically, I would like to know whether customs and immigration procedures are completed in Melbourne or Sydney.
I am also wondering whether checked baggage will automatically transfer through to Tokyo or if it needs to be collected and rechecked during the connection in Sydney.
