Hi, I am going to Australia in a couple of weeks with my family and we want to bring 3 guitars in as carry on. They include a 58 strat, 63 strat and 58 lp special. We are returning there to live after 3 years in the US and all the guitars were bought during that time. Now I don't want to do anything wrong, but what happens with guitars at customs? Do they freak out and have vintage guitar experts to check and value what you have? Do they know vintage guitars, or do they simply look at any beaten up, used guitar as not worth much. For example most people when they see my 58 strat think it is pawn shop junk. What about value? All 3 were bought privately and for cash, so how can I verify the value. This is freaking me out as I worry about huge import duties, and or confiscation of them. Do I need to be exact and careful or risk serious trouble. Or do most people just breeze through, and if they are stopped by customs, say it is a cheap second hand guitar worth a couple of hundred bucks. Like I say I am ok doing the right thing. But what is that? This is making it hard to sleep!
