Hi Martin. A fascinating report.
But just a thought.......
 I really hope you've got yourself an Oriental Reed-Warbler. Very exciting.
Nonetheless, I can't help being reminded of the old medical aphorism that goes 
like this:
"Unusual presentations of common conditions are more common than common 
presentations of unusual conditions." This is a simple statistical reality.
Transposing this into the bird world might read something like:
"Unusual presentations* of common birds are more common than common 
presentations of unusual birds."  [*Appearance, song, etc.]
There are many thousands of Australian Reed-Warblers in Australia and possibly 
one or two (or zero?) Oriental Reed-Warblers.
How does one exclude an Australian Reed-Warbler with a variant call/song, or a 
veterinary condition affecting its respiratory tract, or some other reason for 
having an altered song?
As I said, I hope you are right and you've defied the odds. But it's an 
interesting challenge all the time when rarities are being considered on less 
than incontrovertible evidence.
Regards. Richard Nowotny
