You have selected the Registered Non-Profit Organisation - New membership level.

The membership levels need to be understood is respect to two factors.
1. There is an initial joining fee of $6 - meaning for each level of
membership, there's a first-time-joining fee, and then the annual renewal
fee
2. The fees fall due each year on 1st February, so if you join after 30
June, the fee is half price.
