That is certainly an interesting Gouldian; we see nothing like that here in Japan. Single factor yellow, so we're taking about a cock, yet the yellow of the belly has the softer intensity of a hen. The intensity of the blue on the undertail coverts is unusually strong; in fact the SF yellows we have here have virtually no blue on the lower rump and tail coverts, so close to pure white. Being white breasted the back is usually a much stronger yellow hue than it is.
Here are two of my SF yellow Gouldians, white breasted and purple breasted:

I may be wrong but I have a feeling I've seen images of a similarly shaded Gouldian posted by someone located in South Africa. Is it possible we are witnessing a different mutation at play here? Is this shading (light yellow belly and blue undertail coverts on a white breasted cock) common in Australia? Can anyone post images of such a Gouldian?
