Judging by those Australian lists it looks like there are "realish" Australian players there. Look at the initials:
J. Birkett -> ??
P. Carroll -> Patrick Cummins
M. Church -> Michael Clarke
D. Cordova -> ??? (Dan Cullen? LOL)
E. Cortez -> Ed Cowan
X. Davis -> Xavier Doherty
A. Ferguson ->
J. Fitzpatrick -> James Faulkner
B. Hanson -> Brad Haddin
R. Harper -> Ryan Harris
M. Hendricks -> Moises Henriques
P. Hull -> Phil Hughes
Do they come with statistics or attributes? That would help give away their "true" identity. I won't be downloading this til next week but I'd be curious to know but it looks like they have some with "realish" planets. Why else would they provide so many default teams? If they were all completely fake then I wouldn't see the point given you can get good ones off Cricket Academy.
This also explains why you can transfer certain parts. These "realish" players don't look right or have the right name but the stats, characteristics and maybe attributes are right?
