I can tell Uk's accents. English/Irish/Scottish. Americans all sound the same to me, except southern americans and chicago people. I can obviously tell New Zealand and Australians apart.
I've been told I have a mix of New Zealand and Australian. Some people say I have more Australian, some people say I have more NZ. I really don't know, I think it is that balanced no one can say I have an accent. I would say most of the words I speak like an Australian, but my New Zealand accent slips out now and then still. Americans just think I sound British.
