I'm in the process of applying for a spouse visa, our children already have Australian citizenship & passports. So, whilst they are my dependants and will be migrating with us, they don't need a visa. Will the fact that I put their Australian passport numbers in the application mean that the authorities know this and I don't need to put them down as dependants later in the form? It's very confusing and the form doesn't seem to allow for this situation, unless I'm misreading it. Anyone else in this situation already got their visa and could shed some light? Thanks
