I'd say it is a combination of 2 mutations: White-breasted and European Yellow (single factor) - also known as pastel.

I think there is more to this bird ,if it was a sf pastel the yellow on the belly would be much paler,compared to Australian birds it would not be yellow at all,also there would be no yellow tinge in the back,imo,very nice bird though,garyh

The white-breasted gene does usually combine to result in a yellow back on single factor birds and the degree of this "dilution" is also very variable between individuals.
I don't understand why you would think there would be no yellow on the belly - we are not talking about a blue mutation as well. WB & pastel both retain a yellow belly.
The grey on the throat confirms Euro yellowback/pastel rather than the other known diluted and yellow mutations at play IMO and the breast colour is self-evident.

I think it's a paler-than-usual (they vary) single factor Pastel, orange headed, white-breasted.

Gary, i think you are confused with pastel in blues. This is a pastel yellow with a white breast with the WB contributing to the overall diluting of the body. Again i agree with Tiaris. Craig
