Sydney, my first stop in Ausltralia. The weather here is not so cold as I think.
Maybe I look like a middle-age man or I already have ETA and some stamps from other countries, I only wait for my luggage for a while, and then pass the gates without too much inquiring and inspecting. Just like the Heathrow airport of London, you could take the train from the Sydney airport directly to the city center.
The design of the train is interesting. It's a two levels cabin with some seats in the middle level connecting the upper level and lower level in front and back of the cabin. So, the train could carry more people but also prvide the conveninece for the elders and the disables.
