She?ll b e right AMK, just use the ?Edit? button at the bottom of your post!
As I couldn't hear or pick on any problems with accent?

Good point could it be that it?s engineered by the American agents insistence, that an American accent is a prerequisite prior to being hired. Or because it is not so defined as the British in accent location eg Scots, Welsh, Irish plus 50 odd dialects.
Sure you have geographically defined accents but possibility not as pronounced as the pohms & more as subtle as the Aussie.
With TV shows it is not as bad as Jane Leeves [Daphne ] accent in Frasier. She is supposed to be from Manchester but it sounds more like a mixture of  Yorkshire & Cornish, lapsing into her native Sussex dialect at times, cotton wool in her moth.
Although what does seem incredulous in the old historic films of Britain, is the fact they have all got American accents. There was never any thought of being authentic, which in practice is still being carried out today, especially in theatre.
So as to the question could it be because the show is produced there & they are living with the familiarity of the American accent all the time.
Much the same if the situation was reversed, it would not take anyone long to pick up a Scots or Irish accent living there.

Well, I had two friends from Perth, but I lost touch with them a few years ago.  They were definitely proud of being from Perth!   They told me stories about fishing for octopus....Clive used to work in a mine, I swear I think it was a diamond or gold mine...he said it was really dangerous and his wife didn't want him to do it anymore.  He came here to the states to work as a lifeguard.  We used to make his wife Deirdre say "No" all the time, because she managed to say it in about three syllables!!!
Lovely.

 That?s a pity AMK!
Strine not being my native tongue, As I'm still considered to be a Pohm. I can see this could be exasperating!
The diamond mines are 2000K away in the Northwest of the state, with the gold 1000K to the west of Perth.
Mind you there only about 2 million people in what arguably is the largest state in the world, with 1.2 million living in Perth metro area & the balance in the rest of the state.
Some of the mines in the top end are that isolated, I have driven for a day without seeing another vehicle or town. Similar with the gold mines around Kalgoolie, which are on just straight endless roads.
In fact it takes about 12 hours, non stop driving to leave the state, going to the east from Perth.
We live just 4K from the Ocean near Fremantle, my wife loves fishing & is quite accomplished. While I only seem to feed them all day & get completely bored. Although Ocy is not my teabag! I prefer cray fishing which is much easier where we used to live. All I had to do was sling out the baited cray pots, read a book & pull them in for dinner later.

If you wish or have a hassle you could always ?pm? me & I?d be glad to help you find them locally.

Forgot the obvious exceptions like My Fair Lady/Pygmalion and others where accent is key to the plot.
