Most credit cards points and equivalent miles convert mostly to KrisFlyer (KF) Miles and Asia Miles (AM) in Singapore. It appears that DBS has added Qantas Frequent Flyer (QFF) as a Point Transfer Partner - members can convert their DBS Points into QFF Points at the same rate as KF and AM (5,000 DBS Points = 10,000 Miles).
At the time of writing, the only two banks that allow cardholders to convert their points and equivalent miles into QFF Points are Citibank and DBS. However, I do not personally see much value in converting your DBS Points into QFF Points unless you are departing from a major Australian city. With that being said, having QFF Points does open up a number of interesting redemptions that could be fun to do:
Hong Kong to Taipei on Cathay Pacific First Class (One-way): 26,000 QFF Points
Singapore to Melbourne on Emirates First Class (One-way): 90,000 QFF Points
Singapore to Melbourne on Qantas Business Class (One-way): 60,000 QFF Points
If you find yourself in need of more QFF Points along the way, remember that you can now earn QFF Points on Mileslife as well - if you do not already have an account, sign-up using 'SHUTTERWHALE' and you will receive 1,000 bonus miles after making your first eligible transaction.
