Basically Globird want customers to pre-pay a large amount of their bills. Add $300, $500 or $800 to your Globird utilities account and they'll credit $10, $20 or $50 depending on how much you contribute. At the higher end it's a 6.25% saving over a few months. Better than a kick in the teeth.
I'm not sure if Globird is VIC only or available in other states.
Read the fine print. It seems once the money is in, it may not be able to come out.
