These Pacific Golden-Plovers Pluvialis fulva were photographed by Laurie Knight on the central coast of eastern Australia (in and near Brisbane) on March 14, 2010:
On this modified version of the photo, I have cut/pasted the bill ( "bill length; i.e.from tip to start of feathering on maxilla) below the wingtips; the minimum measured length bill length for fulva is 20mm (average is 22 - 23mm), thus the primary extension beyond the tail tip seems to be clearly more than 10mm:
This individual seems to be in full alternate plumage while still on its wintering grounds (but it could be a bird that wintered further south in the Antipodes that is moving north):
In the image below I have cut-pased the wingtips of the adult bird in the foreground to be underneath the wingtips of the rear bird that I presume to be in its first-cycle: I see no difference in age/wear between these two sets of primary tips:
The above version is how this image arrived from Laurie; below I provide a Photoshop "Autofix" version for comparison:
