I had a quick look at the NAB straight up card offer, it is a bad product.
Take NAB offering for example:
1) $1000 limit, $35 minimum payment, $10 monthly fee
2) $2000 limit, $75 minimum payment, $15 monthly fee
3) $3000 limit, $110 minimum payment, $20 monthly fee
Let's take $1000 card as an example, the credit card has a $10 monthly fee if you do not clear it, regardless the balance.
$10 monthly fee = 10% effective interest per annum, if you borrow the maximum amount and do not clear it.
However if you repay half only, your effective interest is 20%, and so on. If you have $10 remaining balance, your interest rate is 100%.
As long as you have not cleared the balance by end of month, your effective interest exponentially increases.
Once again the bank is trying to rip off the consumers, with some clever marketing.
