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.

Referral database flushed, only participate in the referral system if you have a $100 referral code/link. Click edit in the grey box to do so.
When pming a user from the referral system, also ask/confirm with them that they have a targeted $100 code/link.
Do not solicit referrals in the comments below, that includes mentions that you received the email, we will remove these comments to be consistent/fair regardless of intent. Participate in the referral system and wait for the private message asking for a referral code/link.
Thanks
