I think that's a different rules in different countries thing. Seems like there was another thread here recently in which this was discussed, and my recollection was that the law in the UK was similar to what you describe, which as far as i know, is not the case in the US. If you're on my property, and I've told you to leave, and you don't, you're trespassing. You may very will be correct for Oz.
