Are there any suburbs I should avoid living in?

Without being too specific there certainly are areas that should be avoided as with any town. However generally there are very good areas across each price range, including increasingly popular central, east Wodonga and Baranduda as well as good areas on the West side of town like the more established Federation Park and the Golf links estate. Depending on where you are working you can find good quality areas with good access to transport and roads. Good Luck
