Which is the best street in Franklin?

It depends on how you define "best street". The ones that I would stay away from are Oodgeroo Avenue, Hoskins Street, Nullarbor Avenue and Manning Clarke Crescent. The reason for that is that these roads are the main access points in/out of the suburb, especially Hoskins Street and Oodgeroo Avenue. Anything off from these is fine. Most of the suburb is designed around a plan that incorporates main roads and feeder streets. If you look at a map you will see that the suburb is made up of lots of enclaves. The two obvious ones are just south of Mulanggari Grassland nature reserve (there is a park between the two). If you define "best" as "most expensive" then the most expensive ones are spread throughout the suburb. Proportionally though you will find most of them around Gubur Dhaura (the hill in the north of the suburb. The only draw back from these though is that they are very close to the apartment blocks being built along Flemington Road (dwelling types that normally are noisy and busy). If you define "best" as access to public transport then anything that is close to Manning Clarke Crescent, Oodgeroo Avenue and Hoskins Street are the best because that is where the bus goes through.
