yeah you may as well try. Read the link I posted - be really descriptive and creative in your reasons, size of the game isn't all that matters it's also about effective range and humane kills etc. And don't put roo's down unless you have the permits or they will knock it back
I havent gotten my licence sorted for the same reasons, finding a property owner and all the hoops to jump through is too much effort for some one as lazy as me
Try the owner of Castle Invasion paintball (at the old dizzy lamb park site), I heard from someone who worked for castle that he is also a firearms dealer and sells rifles etc. and owns some big property and would write you a letter. Worth a shot
