From what i have heard
HEAPS BETTER THAN SA
i have met quite a few south africans in melbourne actually, and from chatting to them things are quite terrible over there
most have been here several years and their family moved here because basically someone they knew (while in SA) was killed for no reason and it scared the shiet out of em
yeah they all seem to be happy and enjoy melbourne at least, crime is nothing like what i have heard about over there thats for sure!, and the kind of people stealing a datsun are stupid kids trying to get into an "easy" car but really have no idea, so some a simple device to protect your car would suffice, anyone proffesionally stealing cars would not bother with a bloody datsun thats for sure. i guess the main thing which is hard to protect is a thumping stereo, they get stolen often enough but thats not too serious i guess.
[edit] oh yeah i worked as a labourer for a south african guy (builder) here for a short period and yeah i heard of some pretty dumb stories where people (the previously mentioned darker type) didnt understand what happend, i.e. walking along a plank to do paiting or something and walking past the end support onto the overhang of the plank, falling on there bloody head and having no idea why it happend
