The situation is similar on the Mornington Peninsula (network discussed here). Population density here is not quite suburban but not rural either.
There are scheduled fixed routes but coverage and timetables are limited, even in some more suburban parts of the peninsula. This is despite some routes having to refuse passengers due to overloading as discussed here.
The Peninsula is not considered sufficiently 'Melbourne' to get minimum standard bus coverage that a growing outer suburb might (admittedly after a 5 or more year wait)
If the peninsula is not quite suburban and is actually not rural then what is it?
What a sad state for public transport.
The idea in the article a bus service will need 5 more years before an upgrade when it is already full means the government and the PTV are not doing their job. Electrification is not even going ahead at the moment and this area of Melbourne continues to expand.
Why not just build an elevated double track right down the guts and radiate the bus routes from the new train line. Is there value in rebuilding the old line back to Red Hill and continuing on to the northern side of the penninsula?
Something has to be done.
