As a member of SSAA no doubt you already have some firearms or friends with firearms. To get my letter I went door knocking with a mate around the toodjay area asking if we could shoot on the property 3/5properties were more then welcoming and we still visit all 3 monthly. One property owner allows us full access to fire wood, machinery, camping etc. It takes balls to ask as most cockys are a bit stand off ish but it paid off big time for us, can't see why it wouldn't work for you.

*disclaimer: if you show up on someone's property in a wrx and pull out an unlicensed rifle from the boot.... your on your own
