Frigatebird question from Taiwan

These photos were taken on the west coast of Taiwan last week.

It looks like a Lesser to me, but it is now being called a Great by an Australian authority. I'm not quite convinced. Any thoughts?

I've almost no field experience ID'ing different frigatebirds, but from this article: http://tanzaniabirds.net/articles/Fr...irdingAsia.pdf

The white breast patch seems to match juvenile Great Frigatebird the best. Elliptical white belly patch, with short axillary spurs that start behind the front of the breast patch and don't extend onto the wing (vs the longer axillary spurs of Lesser that start at the front of the triangular shaped breast patch).
