I have been using Commbank Diamond Credit Card for past 15 months and have managed approximately 50k points which equate to around $250 for redemption at Flight Centre.
I I'd like to know from OzBners what credit card so you use to maximise your points? I don't think Commbank gives the best return for the amount of points.
Amex Explorer is the current hotness. CBA Diamond has shit woeful earn rates.
