Melburnians who believe the city desperately needs a rail link to the airport should be careful what they wish for. They might just kill a bus service that is already better than a train could ever be.


So says international public transport planning consultant Jarrett Walker, who argues that Melbourne Airport already has the best public transport of any Australian airport, including Sydney and Brisbane with their rail links.


SkyBus is privately run with a portion of profits going to the state government. It charges $18 for a one-way trip.


Mr Walker, the author of Human Transit, who is visiting Melbourne on a lecturing and speaking tour, told Fairfax Media the key to a good airport link is frequency, not the transport mode.
