Not again! BoM issues Flood warning for Qld and NSW.

"A major rain event will engulf most of eastern Australia during the next 48 hours, prompting the Bureau of Meteorology to issue flood watches from southern Queensland to the NSW South Coast.

"Greater Sydney could be soaked by up to 200mm from late Thursday to early Saturday, potentially leading to major flooding along the Hawkesbury-Nepean River, while Brisbane and Canberra also face the prospect of heavy rain."

@No1 It's not unprecedented.

A few years ago, after a particularly bad flood, the entire town of Grantham in Queensland was relocated to higher ground: https://www.brisbanetimes.com.au/national/queensland/grantham-reborn-meet-the-little-queensland-town-that-moved-20200227-p5450g.html

If you have a town that's in a floodplain, instead of constantly needing to rebuild it every couple of decades (or less) because of floods, it can make sense to do so.

Banks and insurers look at the risk profile, and then adjust the cost of borrowing or insurance premiums accordingly.

At a certain point, it becomes far cheaper to just call in the bulldozers and rebuild elsewhere.
