Thanks rofbp. There are repairs on Fr. Matthew Quay as well, where there are no steps, so I'm not sure how they're selecting what's to be repaired/cleaned.
I think you're right about the wooden 'wharfs'. (Wharves?) I have a certain vested interest here, I've a city centre apartment with no outside space whatsoever, but a little river-side wharf across the road. It would be a fantastic for residents in our area if you could sit down there, rather than it being fenced off as it currently is. The Georges and Alberts Quay wharfs could be great, if re-used for cafe/walkway space. Sadly, they're in a fairly terrible state of repair, I doubt they can be salvaged and I doubt the money (or inclination) is there to replace them!
