No surburbs are safe, not even Adelaide city itself

(well at least, not entirely). You can live in the city apartment and have your car window smashed even in secured carparks (happened to a friend of mine who used to live in one of the city apartments).
There are a few surburbs which are close to the city CBD, but by expanding your travel time range from 10-30minutes made a lot of difference my friend. If you say 10-20minutes, then it will make some sense.
And then moving on, is the time range referred to a specific hours of the day? You know during peak hours it can time a longer time to get to the city than off peak?
Well if you want to get to the city CBD in that time range during peak hours with public transport, any surburbs between the 5-10km radius from the CBD will do.
Of course, if you catch the train, it will be more reliable and perhaps faster (? I haven't catch a train before, but from my technical understanding, they should be faster) than the bus, because you might get caught in traffics which can cost you a lot of time.
I used to live 5kms away from the CBD, and it took me 20 minutes drive to get from my place to the CBD at 8am during peak hours, so it all depends.
