The exchange rates for CBA foreign transfers are generally poor compared to using an FX specialist
However for those interested in CBA currency exchange and buying foreign cash the article notes:
Comm-bank exchange rates for travel money are comparable to those of the other Australian banks but somewhat less than those available by ordering your foreign currency and travel money online
Another point the article makes is that the bad exchange rates on offer for foreign transfers need to be weighed up against ease of use of using your bank to transfer rather than the hassle of using another provider.
A few user comments suggest CBA offer very good rates for Indian Rupee.
