Oddly enough, I've always been fascinated by Australian accents. It somehow made me particularly happy especially after I watched this video (https://www.youtube.com/watch?v=9QCgqQdmr0M) where I couldn't understand a single sentence. I then tried to learn this accent in Sydney and was discouraged by many of my Aussie mates. Now I just have a little bit of the Sydney accent, which is roughly /ai/ -> /oi/ (bike -> boi-ke), /ei/ -> /ai/ (day -> die). I don't know why, but I like this accent, it sounds and feels warm, open and full.
