Resurrecting an old thread because I have only now discovered this, it is certainly not clearly stated and you need to find this detail in the T&Cs:
The following transactions are excluded from earning
points: BPAY transactions, balance transfers, cash
advances (including a transaction treated by the Bank
as a cash advance, for example, utility bills paid in person
at a bank), purchases of foreign exchange, credit card
insurance premiums, travellers cheques, interest charges,
Qantas Frequent Flyer Direct fees, Bank fees, Card
account payments, transactions deemed by the Bank
to be for business purposes and any other transactions
which may from time to time be excluded by the Bank.
And it is not just BPay, note QFF Direct fees and Credit Card Insurance premiums plus utility bills paid in cash at a branch.
