Gull-billed Terns, Goolwa, SA

Today (13/12) I went over to the Goolwa Barrage/Beacon 19 Ramp area to work 
through the Pacific Golden Plovers which turned out a difficult task with 
the stiff NE breeze buffeting the scope. However, I did see 3 Gull-billed 
Terns (2 in full breeding and 1 in full non-Breeding plumage). The question 
I have is: Would the non-breeding GBT be of the Eastern Asian race 
'affinis', ie. do they migrate to the southern coast of Australia?  The 3 
GBTs were in different locations so I could not compare sizes accurately 
although I got the impression the non-breeding one appeared to be of a 
smaller size .
