Been here nearly a year now, from the UK. Love it...nice laid back pace (Which is great, until you want something quickly!!) and not really noticed any crime in any of the suburbs I've been too. I'd happily live anywhere I've been in Aus though, so it's not as if you're going to get a bad comment out of me anyway! :)
Can't help you land wise - but as other's have said, you're going to be looking a long way out of the city for that amount of space, and unless you choose somewhere in the middle of nowhere, I wouldn't expect it to come cheap either. Me, I'd love to be in the middle of nowhere with a big block of land as long as I could get a fast Internet connection for work, but my wife is a city girl, so we'll never leave the suburbs!!
