The obvious choice is that long odds? Anyone who knows anything about Sydney, glamour girls cannot avoid Bondi and the Eastern Suburbs. That's where his partner probably already lives, and that's the obvious destination for Cronk.
EDIT: I've just checked her wikipedia entry, and:
She has also played local football herself, for
Lindfield F.C. on Sydney's
North Shore
So... I stand to be corrected. Fox Sports Studios in Sydney is in Artarmon, married with the above suggests she works and lives on the north side of the metropolis. That would make Manly the obvious choice...
except for the matter of DCE. So... still think Roosters are likeliest, but stranger things have happened. Eels and Manly are my second and third prediction.
I can't see him coming to the Bulldogs.
