Do you need to provide salary information if taking up offer to upgrade Amex card?

My wife recently was offered to upgrade her Qantas American Express Card to a Qantas American Express Ultimate Card and receive 40,000 points (after 3K spend), $450 too spend on qantas flights etc, etc. Has anyone had this offer and then taken it up? The landing page doesn’t seem to have the income requirements that the normal Ultimate T & C’s state. She won’t qualify if they ask for proof of income so I don’t want to waste our time.

Most likely she will have to provide proof of income that matches the eligibility for the card. So I’m afriad no dice there.
