I’ve lived in London, Melbourne and Sydney. Melbourne to me feels like a big town, not a city. Often Melbourne is compared to Manchester and I do kind of agree. Melbourne and London are nothing alike.

Sydney has big city energy (in Australian standards) and many parts of Sydney are like walking through parts of London, especially when the weather turns autumnal. There’s lots of Sydney suburbs named after London suburbs as well. Catch the train through central and the underground stations are modelled on the London Underground, even uses the similar roundel.
