@jaystephens @ketanjoshi.co And then we have Australia's next great city, Parramatta.
It's a city that, roughly once a year, has a harbour...
This from Parramatta City Council itself: "From the earliest days, the changeable nature of the Parramatta River, and other waterways, has brought with it the risk of flooding.
"Today, our CBD is one of the most flash-flood affected areas in the country. Our challenge is to live with the river in all its various conditions."

And this from a top State Emergency Service official in 2019:
"A senior SES official has warned that Parramatta's CBD could be overwhelmed by a flash flood in as little as nine minutes, giving residents little time to evacuate.
"George Jeoffreys, senior manager for risk reduction and avoidance at the NSW State Emergency Service, cited the difficulty of predicting flash floods."
You had parts of Parramatta's CBD flood in 2020:

And earlier this year: https://www.abc.net.au/news/2025-03-26/nsw-pseudo-monsoon-humidity-flooding-rains-qld-nsw/105095284
And of course there's pressure to put new high-rise developments right on the river edge: https://www.smh.com.au/national/nsw/sydney-council-rejects-build-to-rent-tower-plan-over-flood-risk-20240108-p5evsm.html
