I live in London but I'm originally from Australia. I think there are lots of unique and inspirational designers in aust, we are really lucky. It's hard to see what you -do- have until you move away though.
and as to trend clones - I think it's like that in most cities.
In australia there are lots of independent retailers in most cities (stocking Aust and international designers), and it is not too hard to find something 'unique' for a reasonable price. I find living in england most towns and high streets are completely over-run by chain stores - topshop, h&m, zara, etc. Don't get me wrong, they are okay, but it is much harder to find something that isn't totally mass produced and for a reasonable price!
