G’day Dominic,
The first impression from looking at your bird is a darkish throated female Great Frigatebird and that’s what I think it is. Shifting the levels around on your two images shows a blue eye-ring and the bird is lacking white tabs into the underwing, none of this is good for Lesser in the Coral Sea. I would say that the darkish throat, which is probably the reason for your caution, is not a problem and within the spectrum for female Great Frigatebird.
Cheers Jeff Davies.
