Paying card at australia post

[blacksultan]

Can one pay a nab ( or any other credit card ) at australia post using another debit card ?
Alternately can one transfer funds from one bank account to another using only cards and no cash ? I knew you could do this years ago ,

A “debit card” will be linked to a cash account of some description? So you can just EFT / BPay from that to the CC?
