Hobart is about as far south as you can go in Australia is Hobart, capital of.  Tasmania, and a very long way from London.  it  has that distant feeling of a city at the end of the world with spectacular views of sheltered bays and secluded coves, as you come into land.
The settlement near Hobart was the second in Australia and must have been like going to another planet for the poor wretches sentenced to end their days here. It's a bit more civilised now with posh restaurants where the prisons used to be.
