Suncorp Insurance are offering $200 cashback into your bank account after you hold the policy for 60 days. My life insurance quote came out at about $10/month but YMMV. You could potentially cancel before the third month for approx $180 profit. Or hold onto it for the third month to make sure you get the cashback.

So do you have to set up a bank account with them to receive the cashback?
