Hi.
I'm an Aussie teaching here in Japan. At times,
my students cannot understand my Aussie accent. Even simple things such as "What is your name?" and "Where is your home?". But as soon as I change my pronunciation to that of an American, then they understand straight away.
I wonder.... should we be teaching students always with the American pronunciation, or should we use the pronunciation we were born with? It gives me a headache when trying to mimic Americans.

and I don't like it too as I'm proud to be Aussie. Not that I have anything against Americans though, don't get me wrong.
They have great movies!
One of the biggest buzzes I get is when I hear my 3 year old student say the days of the week using the Oz pronunciation.
It's GREAT!
