Welcome on board.
Join here, if you mean that you want cheaper Qantas Club membership.
AFF, via its sheer number of members, have an agreement with QF where you can get discounted Qantas Club annual membership.
Think that there is a specific branch on this website.
Not sure, as I don't fly that often anymore to make Qantas Club, we call it QPlonk on here, viable.
If you mean like, discounted flights, on that side of things, I will leave the others to answer, as they might know a corporate TA who might be able to help get you cheaper QF flights.
Qantas Club members can access lounges at 24 Australian airports and many more overseas. Our guide explains everything you need to know, including how to gain entry.

QFF itself, does not charge an annual renewal fee, if you have received an email saying so, its most likely a scam.
QFF only charges a once off joining fee, and sometimes, no fee is charged if you join under certain schemes.
We do need more info.
