Millonario:
Be careful with the term "validate" here in Australia. It does not carry the same connotations as in EASA member states. Perhaps you have already seen that from the quoted law, above. In general it is true to say that all Australian licenses and ratings are valid for the lifetime of the holder, but privileges cannot be exercised unless... see above.
No doubt, when or if CASA works out how to update aviation law, regulations will be clearer and easier to find.
