A hot British or Australian provider that tours the US. I’ve had a taste for the accents. Do we know anyone out there and if so please share.  

Review Search uses "ethnicity" to imply country of origin or ethnic descent. There is a checkbox for English but not for Aussie or NZ.  There is also a Language search selection: there's a box for English but not for Australian  There are lots of recent hits for "English" ethnicity that you can narrow down by prefs (geography, hair color, age, services, ...).

Wichita, KS + English gets one hit for Gina from 17 years ago. Maybe she's still active?
.
Alley-Syd (aka Aussie Alley) has made some posts to the board recently. I haven't met her but I'd guess that she's from down under maybe even Sydney, Australia.

(See my many post to S&P about changing "Ethnicity" to two or more new categories.  Search S&P for "complexion" (words) and impposter (author).  
1. Complexion, with a skin tone chart, to get that correctly. E.g., there are Brazilians that range from Coconut to Espresso. Likewise, there are many AA who identify as AA but have skin tones that range from Coconut to Espresso.
2. Country of Origin or Cultural Background. One can have a Russian background / culture / accent but have been born and raised in Brooklyn, NY! )

the chart.  If you can get me real women in all of these these colors, I'll take one of each . . . . but not all in the same day.  Lol.

Obviously from New Zealand originally. I met her a few times but never sessioned with her (not my type). She's older and has long legs with a nice, natural body. You might check the LV scene to see if she's still there.
The NZ accent is a lot like the Australian. I can't even tell the difference, though I'm told there is one.

If she ever comes back to tour from the UK, check out Valerie Foxx aka Valerie International. She's a hot legit porn star who is quite fun to be with and will rock your world.

She’s still around. She goes by Dr. Kiwi. She’s on Twitter and has her own website under Dr. Kiwi. I haven’t seen her so I can’t offer much more than that.

I seen to recall her TER username was Kiwigirl.  

I recall her saying she was in grad school for a degree in sociological/sexual matters. I guess she graduated. I wonder if she got extra credit for all the dick she sucked?

She used to be in LA, then moved to Vegas. I'm sure she's still around as I see her ads all the time.
But again. never met her and I don't know about the accent.

If TER was using my suggested "Complexion" as a Review data field (with a skin tone chart for Reviewers to check a box or pick a number: IMAGES, not ADJECTIVES) then you could find them for yourself with a simple search of Reviews!

"Review form suggestions:  
a. switch to a pallet of colors for complexion (instead of "race"): reviewer clicks the swatch or picks a number
b. switch to something like cultural origin or country of origin (instead of "race")  
c. switch to a pallet of hair colors for hair color: reviewer clicks the swatch or picks a number.
Etc."

it all in a sociologically sexy way, she probably did.  

But, as I said, I never sessioned with her. I do recall her dancing sexily at an LV M&G and shaking her very nice ass. I'm sure she still has a nice ass, though that M&G was about five years ago, so....
