Hey Lads. You wouldn't have seen me because I'm new to the forums, but lately I have been wondering for a while about applying for a gun license and how I should go about doing it. I have just recently turned 17 and currently live in Brisbane and I am planning on obtaining CAT A & B + H (Magnum). One thing I was wondering is if I should try to obtain a minor's license now instead of waiting till I turn 18. Would that be easier than just waiting till I turn 18? Also should I/am I allowed to apply for all those licenses at one time. Or would it better if I did them one by one.
Also I am curious about the "magnum" (over .38) license. I prefer to obtain a magnum license because I would like to option to get a chance for some really hot rounds later own and also whats the point of owning half a license. Never got it either because somehow the government figures that a high powered low capacity handgun is more dangerous than an intermediate mid capacity handgun, but I will leave politics for today

. But is it much harder to obtain a magnum license Cat H than a regular Cat H.
Finally a little more of a bio about me. I think it would best to explain my understanding of small arms so you don't think I just got the idea to apply out of call of duty or something

. I have had not all that much first hand but luckily enough I have had some experience with F88S, retired SLRS and also a junky Pakistani AKM at cadets. But I consider myself having a fair amount of knowledge regarding both civil and military weaponry as I have been reading books and articles regarding firearms since I was 13. One last thing that might be interesting and helpful, is that I have quite a large police family although most of them aren't actually interested in firearms personally, but I thought maybe they could be of help?
Hoping on getting
SP01 (9MM)
SW686 (.357)
Mosin M91/30
Well anyway that's it from me, hope I didn't come off to poorly.
Thanks!
