Not sure if this helps, but the ds i have is Actually from America, some friends and i ordered 4 of them in bulk straight from the U.S so we had them in Australia before they where released...
But for the record because mine is Amercian DS (Not DS lite) the charger that came with it is a completley different charger and it wont actually fit in Australian power sockets, but the good news is just grab an GBA charger and that will charge it with no problems
