Avoid the Qantas Frequent Flyer join fees

Qantas Frequent Flyer (QFF) has a fee to join, but only if your address is in Australia or New Zealand. However currently there are two promotions providing free joining.

Australians can join QFF for free by transferring credit card points in by 31 March.
New Zealanders can join QFF for free by joining before 31 March.

Since a QFF account, even if empty, can be used to look up Oneworld award availability, it is worthwhile signing up even if you do not intend collecting QFF miles.
