Depends if it's your thing... Only $10 anyway. It does have "more tables of gear for sale than any gun & militaria shows in Australia". Every time I go to one of those shows I always return with some utterly useless junk like broken ammo boxes, dummy shells, blunt bayonet etc. Did get to shoot a Desert Eagle at one though, that was just pure awesome .
there are some coins also which I could be interested in...was just wondering if someone has attended this show before in Brisbane
If you are into collections then it worthwhile going. There is one in Perth every few months; Something similar to this. Badges, Buttons , military item etc. Being anniversary of ANZAC alot of people will attending this event. Best is to be there as earlier as possible. Good Luck in what ever you are looking for.
