This is weird for several reasons. For starters it’s only on one side of the road, although, they might not be finished yet. Secondly, rather than put the bike lane on the road where it belongs, it’s on the footpath thus endangering pedestrians.
As Algernon said on IRC, when adding bike access they saw it better to take away pedestrian access rather than road access. Frome Road narrows to two lanes behind the photo, so a bike lane either side of the road would be no great loss.
The whole strip is very pedestrian un-friendly as it is. Although there are several pedestrian crossings, they’re all in the wrong spots. For example, the main entrance to the Adelaide Uni Med School is directly opposite a gate into the rest of the campus, so the majority of students walk in a straight line between the two. There are pedestrian crossings about 100m either side of this spot, both of which are hardly used. One’s too far north and away from the most of the buildings along the road so is hardly ever used.
IMO, bikes don’t belong on footpaths and pedestrians are more important than cars.
