Tough one, because i was born in Alice Springs and lived in Mildura for most most of my life (around 10 years).
But i would have to say Mildura because I cant really remember Alice Springs and I love Mildura, though the funny thing is i hated Mildura while I was living there and couldnt wait to get out of the place, but now i love it, lol
