St george has reduced its 3 year fixed rate to 5.59% which in comparison to CBA is a great deal. I have included a comparison link and also a graph i have compiled from Reserve bank of Australia data showing these rates are now close to historic lows. The rates are available direct or through your broker.
3 Year Fixed rates with other lenders
I must add as well St George currently has a $700 refinance rebate offer at the moment and from us a 400,000 loan would be $1,746 commission refund so your effective rate over 3 years would be around 5.39% for a 400k loan with the cash backs!!!!
