crinkles, giving up is absolutely the last thing that you should do, as that's exactly what they want you to do, and why licences are now $200 for 5 years etc. etc.
I have never seen ammo sales figures since the "uniform" gun laws were set, however, my club has about 80 members who were lucky to shoot 50 rounds of .22 a year, who started shooting thousands of rounds in club activities.
If you want to hunt, reacreational/vermin, you only need a property owner to give you a letter stating that you are allowed to shoot rabbits on his property...join the SSAA, and get (IIRC) $20M of public liability insurance, which helps when talking to property owners.
If you join SSAA, you can shoot at their ranges, or have attendances at gun shows counted towards your 4 attendances.
If you joins a NSWRA club (Coffs has a really good club, our members are up there regularly), they have r8imfire and cerntrefire for $128 (NSWRA), plus what the club charges (ours around $75) for targets, trophies etc.
Don't give up.
I had my 15th B'Day present at risk when the laws came in, forcing me into a club. Now I've got 6 rifles, and some new friends.
