Looks like ING has upped their referrals back to $100, most likely targeted (as that's how it has been in the past).
Here's what it says in the email I received:
ING is Australia's most recommended bank.
So if you've got friends yet to discover ING's great value, send them our way and you could bank a $100 reward - each!
This is what is required (before the 31st of July):
Go to ing.com.au/everyday, open a new Orange Everyday and enter the promo code in the promo box at the end of the online form - this part's really important otherwise neither of you will get your reward!
Deposit $1,000+ (such as your pay) from an external account into your Orange Everyday account within any calendar month.
Open a Savings Maximiser (if you don't already have one) and make a deposit into this account.
Make 5+ settled (not pending) ING card purchases using your new Orange Everyday card within any calendar month.

Anyone know whether new customers signing up after this point have any possibility of being targeted for the same ongoing offer?
