I think i've come around to the idea a little more since i last posted on this plan,
-
The riverfront could be designed as a green corridor between Heirisson Island and Kings Park. It would act to cool a large part of the city, and also be great for the city's bird life. Possibly other small marsupials as well, if the design was thoughtful enough.

There were a number of historical landmarks along the waterfront, I believe the original Emu and Swan Breweries were around that area, or maybe nearer Elizabeth Quay. Reconstructions of these could be a cool way to reconnect Perth to its early history, as 'Perth', that we cast aside.
