what are the social,family and cultural influences on the female age
bracket 35-44 years of age in australia which affect their buying
behaviour.

This sounds like a homework essay question to me.
Don't expect any fast, easy answer from anyone here.

I'm much older, male in the USA, so perhaps I should not comment. I
think differences will be minor with rare exceptions. Our attitudes
are mostly formed before age 5, so our instint to conform is stronger
or weaker dependent mostly on the example of our parents and others
living in our childhood home. Our buying behavor is driven largely by
our need to be like other people. Much of what we purchase is fluff
that we could live without better, except unfulfilled compulsions can
make us uncomfortable, perhaps ill in a few individuals.   Neil
