Australian yellow is autosomal recessive, just like blue.
Your first pairing will result in green birds which are all split for both blue and australian yellow. They will have purple breasts unless both your birds are split for white or lavendar breast. The babies could have either red or black heads, depending on whether your cock has a "double factor" red head or a "single factor" red head.
Is your silver cock an australian yellow which is also blue? Or a different mutation of yellow?
If this cock is australian yellow and blue, your second pairing will result in mostly green chicks but also some blue chicks. All chicks will be purple breasted (unless both birds are split for white or lavendar breast) and split for australian yellow, and those chicks which aren't blue will be split for blue. The head colors could be black or red for the same reasons as above.
If your silver cock is a "double factor" sex-linked pastel (what American's call yellow body) and also blue, the chicks from your second pairing will all be purple breasted (unless both birds are split for white or lavendar breast) and could be yellow and split for blue (hens), silver (hens), dilute and split for blue (cocks), or "pastel blue" (cocks). The head color could be red or black, again, as explained.
Keep in mind that genetically red headed birds will have their heads appear nearly white if they have a blue or silver body, and that genetically black headed birds will have a grey head if they are single factor sex-linked pastel, and white heads if they are silver or yellow in body color.

"Double factor" is equivalent to homozygous (2 copies of the gene are being carried by the bird in question). In order for a bird to receive two copies, one copy must come from each parent.
"Double factor" is actually not correct terminology, but it's kind of rampant in the finch world in my experience, so I use it even though it's more proper to say homozygous.
