Mastercove has taken up NAB CC for 75,000 points,Bankwest for 50,000 points, St George for 30,000 points,Amex Velocity for 110,000 points Westpac for 100,000 points and ANZ for 75,000 points. If you read up on their respective websites you may find something that is a fit for you. I think AFF has threads on each of these. You should also take care that you don't overdo it as your credit rating can take a beating if you mess up.
I think I left out Citi and he has not done HSBC which could work too. Then there is Amex Explorer and Amex Ultimate if you need big sign ons.
