I personally voted to close the question because, as jmac pointed out in a comment, you seem to be asking four different questions, like: "(1) what is 'local experience' (2) how do you overcome unwritten requirements (3) what do Australian IT employers/recruiters want (4) how should I handle this job rejection".
I'm not sure which, really, is your primary question, or how close these assumed questions are to your primary question, but if these four do encompass your questions, I would say that 1 is possibly answerable although with a lot of conjecture unless it is something specific to Australia and someone here knows that, 2 I believe has a duplicate somewhere on this site but I haven't looked yet, 3 is really broad, and 4 is probably unanswerable by the community.
But as with everything, a focused question is a better question.
