Shorebird - Tasmania

I had this one posted as a Red-capped Plover in my Big Year Chalenge, but Dev has me questioning the ID - taken Orielton Lagoon (RAMSAR listed site) east of Hobart, Tasmania. It's the only photo I have, and not that great as far as providing prominant features.

I did get a photo of a Red-cap, ID was conformed by some BirdLife Tasmniana members, but now think I have uploaed the wrong photo?
