It's very tiny, can't believed I didn't notice it before.
Looks highly inadequate to me, although I suspect they could counter that for a bike to use a ped area/footpath etc it has to be specially allowed i.e. with the blue shared use signs, and hence if there's no signage / nothing visible you aren't entitled to assume you can use it.
However - you might counter that if they felt necessary to use any sign they are obliged to use one that is actually visible and sufficient.
