Lol Sunbury is a disgrace. The real answer is New Gisborne and Willowbank estate. Not really many places to avoid.... there’s older gisborne where it’s a bit cheaper and New Gisborne where it’s a bit more expensive. But it’s not like the city where there are definite areas to avoid for safety purposes. if you want to be safe and not robbed, stay out of Sunbury and Melton.
