What Shorebird is this? SEQ

Hey,

Just needing to know what shorebird these are. They were seen at Thorneside, QLD. There seemed quiet small and were in a somewhat large group. 

I think they are a “Great Knot” although I’m not sure if that lines up with their migratory arrival etc, just wanting other opinions.

thanks,

(sorry about the pictures, it was the best I could do)
