Firefly Express by bijo69
I took the Firefly bus from Stawell to Adelaide and it was really a comfortable 6hr trip!. The bus was quite new and had lots of leg room. There's a toilet on board and dvds are shown throughoutr the journey.
Firefly Express serves the route Sydney-Melbourne-Adelaide daily. The ticket from Melbourne to Adelaide is e.g. 55 AU$.
