I got an Email from ING Direct that offers $75 for you and the person signing up, if you can get someone to sign up. I'm not sure if it's a targeted Email, but it has a unique 'friend code'.

These are instructions from the Email:
How it works for your friend
To be eligible they need to be a new Orange Everyday customer.
They need to register their details (including their unique friend code) at the URL provided below and open an Orange Everyday bank account by 10 October 2014, and
They must deposit $1,000 or more (like their salary) into their Orange Everyday bank account by 31 October 2014.
How it works for you
Share this with your friends who may be interested in an Orange Everyday bank account.
Once we confirm they've registered, opened an Orange Everyday and made a deposit ($1,000 or more) into their new account, we'll send you an SMS to let you know when your $75 credit has been deposited into your account.
You also get the benefits of existing deals
