Up to what age can you apply for residency and citizenship in Australia when moving over as a New Zealand resident?

Ok, we looked into this as we're getting on a bit! it's 45 max. for permanent residency if you apply under the skilled migrant Catergory (not sure about other visas). After you get permanent residency you have to have lived in Oz for 2 years before you can apply for Citizenship. If your in a skilled shortage area the only other way around this is to get your employer to sponsor you.
