These credit cards are reward cards with free insurances. Platinum card has five insurances while Signature has six. Minimum income apply. These are the best fee free credit cards I can find to date: no annual fee + 0% BT offer + reward points(1.25/1.5 per $) + comprehensive insurances. Enjoy.
Edit: this has been extended to the end of March or July 2014.
I'm in the same boat. Have requested quite a few reassessments. They've been in touch with my accountant numerous times that satisfies the minimum income and they even know I have a NAB and Westpac card with $18k limits on both which are to be cancelled for the Signature. Very weird process.
Funny thing is that a few weeks ago I was cold called being offered a Signature which I said I'd think about it and a week later I see this offer and can't get it Signature only Platinum. Very weird.
