While buying a ticket, I checked the airlines and it is exactly like this photo. Does it mean we just stay inside the plane for 1 hour and half and then leave or ...? It writes 'no aircraft change'.
It is important since I need to know whether I need to have a transit visa or not and in case we do not exit the airplane I think we do not need it. Otherwise, I am sure due to nationality we need to. On the other hand. 1 hour and half of course is not enough for transit or so. This is why I doubt.
An Australian transit visa is required unless you are Australian or New Zealander or your nationality is exempt for an eligible flight.
This is a fifth freedom flight with passenger operations in Adelaide. While you might be able to stay on the aircraft during the stop and not pass immigration, embarking and disembarking passengers means that it is considered a flight to Australia and everyone is subject to Australian rules. Australian authorities implement an advanced passenger information system that includes electronic visa verification; without a valid visa you will be refused boarding for any flight to Australia.
Even if you wouldn't need a visa if you decide to stay on the plane, there is always the risk that they change the airplane on short notice, for mechanical reasons or whatever. If you then need a visa to get out of the one plane and into another, you could be in deep trouble. It is not the airline's problem, but yours.
So make sure you have what you need to enter the terminal.
