About Membership

The $25 membership fee (per calendar year) entitles a member to seek enrolment in up to five courses in both Semesters 1 and 2.
Most courses have a maximum capacity and if there is over-enrolment people will be wait-listed. Often a negotiation process is employed to endeavour to meet the needs of as many people as possible.
