Of course i have to declare my self interest in this but it seems to make more sense to place 1 supercharger in Bright, This would service Hotham, Falls and Buffalo with enough in reserve for 60s as well as 70s and 85s and ties in well with the Hume chargers. Alternatively Omeo allows access to Falls via the back road (although the High Plains Road is often closed all winter) as well as Hotham.
Absolutely @Bright, would make a lot of sense. And you wouldn't do the Bairnsdale route just for alps access, way too low demand compared to the Bright/Harrietville route I would think. More for Gippsland lakes and the coast route to NSW with ski fields access as a bonus. Can't see it happening for a long time yet though, the route to Adelaide would be the most likely major avenue to be enabled in Victoria next you'd think. Bright could happen a lot sooner given it would already have the Hume route supporting it and would be an easy enabler of a lot of extra routes.
