Still Question is same !!

What do you want ?

If you are the shop owner, & you want to support legitimate busines. Whats the name of the shop or any info ?..

If you don't own any shop, who cares who has ABN or TFN, that's not your business to check, if that still bothers you complain to the authorities, not here.

Are you an accountant ? Promote your own business & help people for tax returns, Abn, TFn, or book keeping services.
