The recent storms across Perth certainly tested the river walls. Here are some photos of the Como beach area, showing the effect of waves, active erosion close to the freeway and the greater effect of back- flow erosion after waves, with traffic in the close background. (Click on the images to enlarge them.)
Here, too, are some pictures of the palm trees, a few weeks before, and then during the storms. Previous weather events had removed nearly all of the root supports for these trees. The City of South Perth wisely removed the trees when the weather forecast predicted storms. Had they not done so I am sure that the trees would have crashed across the bike path and affected freeway traffic.
The world is in constant change, and always has been. Our challenge is to manage our place in this change.

I'd be interested if you could expand this discussion on your blog and describe possible solutions that don't turn the river into a walled estury.
Some form of dykes may be necessary over the coming century if we aren't successful in adjusting our human contribution to rising sea levels.
Should we be planning to redevelop the freeway so it and the train line are built on a plinth to keep the water out of South Perth and Como ?
In the meantime, can we use low impact (visual and environmental) buffers, either natural features or man-made, that maintain the features of Como Beach that are important to residents and users of the public space ?
