Is this Melbourne’s narrowest bike lane?

Is this Melbourne's narrowest bike lane? What exactly is the point here? I wonder if it actually offers cyclists any safety if they have to move out into traffic every time there's a parked car? I'm not sure that it inspires me as a prospective cyclist. Pic from Brewer Road, Bentleigh. I thought Neerim Road in Carnegie had some narrow bike lanes, but those are wider than a parked car.
