Just googled some more suburbs to avoid and also the better ones.
Lets start with the not so good.
Depending on your housing affordability, the areas best to avoid are: Ravenswood, Waverly, Rocherlea, Mayfield, some of Mowbray and partly Newnham.- these areas are more prone to bad behaviour, lower socio-economic housing.
Areas that are most preferable are Prospect, Newstead, Riverside- Trevallyn, West Launceston, Kings Meadows and Norwood.
