My accent is weird - no, I'm not the first to say that about it. I was born in Wales, UK, so I naturally have a Welsh accent. Then I moved to Australia a few years ago, and kind of picked up the lingo. Now the Aussies easily pick up the British accent, but the Welshies (I know, I made up a word!) claim I speak with an Australian twang.
Note: Australian accent sounds kind of like Cockney. If you've heard both, you'll know what I mean
