From ProgSoc Wiki
ProgSoc can accept payment either in cash or via bank transfer.
Membership for a calendar year costs $10.
This is basically a matter of turning up to one of the regular ProgSoc meetups at some point to see one of the people in the ProgSoc Executive. Make sure they write up a receipt for you, or else the fact that you paid may get forgotten.
By Bank Transfer
Using Internet banking, transfer the money to:
The Programmers' Society St George Bank Australia BSB 112 879 A/C 118 075 761
When the system gives you a receipt, read the Acceptable Use Policy, and fill in the form that would appear after you accept.
