There is a bus service from Mount Hotham in winter, leaving from the Transit Center and opposite the Big D ski lift. Bus travellers would catch the Melbourne-Bright-Harrietville service to Mount Hotham and change at the transit center, but the bus is usually used by people skiing at Hotham and staying at Dinner Plain.
Northeast Coachlines operates HothamBus.com from 2013, offering daily & overnight services from Melbourne to Mt Hotham, Dinner Plain & Falls Creek from June to early October.
