Lookindown, from the ATO website on eligibility to claim self education expenses (my bolding):
You can only claim deductions for the expenses associated with self-education that are related to your income earning activities while you are studying. If your self-education was to help you get a new job, you cannot claim your expenses.
If it is for a new job, you can't claim. As far as I can tell, and it's not very specific, it doesn't matter that your new job is in the same profession as your old one, it is still a new job.
If you feel like claiming anyway, and they don't audit you, well, that's up to you
