I've just signed up to OZ Club as a replacement for BD DC. I like the two year qualification and terms as a frequent Y flyer, the possibility of lifetime status with a carrier that has a life, and the 10 year validity of miles, which for me was a big point over TK, SQ, and NZ. No own metal requirement for status unlike AC and UA/CO. Earn-burn is not great, but the stopover allowances are good if you earn enough to redeem.
