I'm going to studying abroad next semester in Melbourne and would like to get an idea what the knife laws are like there. I was planning on bringing a few of my folding knives with me and would like to always have one of them on me while there. I'm not going to bring any autos, balisongs or double edged knives. How strict are the knife laws there? Is there a blade length limit for carrying folders? Can I carry them openly (clip visible on pocket)? I would prefer to carry something like a Spyderco Delica over a SAK but don't want to get in any trouble while there.
