Yes, it does not work for me - although I should point out that the local rail passenger service stopped over 50 years ago - if it still operated I could get the train into town with only a 6km drive and park at a relative's house two minutes walk from the station. Mind you, the railway is inoperative at the moment after a bridge was destroyed in a bushfire in December, and won't be replaced until the middle of the year. And my annual pilgrimage to Sydney is by train, although parking is, as you say, an issue.
However, a large proportion of the fuel used in Australia is used in commuting in Australia in single occupant cars, which really could mostly be done in a sensible public transport system.
Remember that most (about 90%) of Australians live in urban areas and two thirds live in the capital cities, and for a large proportion of them most fuel use is in commuting to work.
