The closest thing we’ve have in Sydney recently was this pool, but that was from beach erosion at Collaroy.

Wow. Thank you.

It’s reasonably common to have bits of road right on coastlines need urgent repairs due to landslip movement (either undermining or collapse from above), and we’ve had cyclones cause coastal erosion that undermined houses.
If you were to move the question inland a little then yeah, there lots of roads and houses getting swept away by riverine flooding.
Thanks for that on undermining of coastal roads, I hadn’t heard of those.
I have heard about landslide problems from above, which originally led to the development of shotcrete and since then a whole series oif improved engineering solutions.
Agree totally with riverine flooding. Needs an urgent fix.
> beach erosion
Beach and sand cliff coastal erosion is very common, even inside Port Phillip Bay. Those bulldozer tracks all over our beaches detract from the beach experience.

Yes! That’s one of the houses from Diamond Bay Vaucluse that had me worried 40 years ago.
