Based on climate change models and coastal flood zones. She cities be planning for these changes and zone land accordingly to the predictions?

For example, they have reasonable understanding on low lying areas that will be lost when the sea levels rise over the next 100 years for example. Should those areas manage this risks by terming the land like 1 in 50 risk of flood zone or something similar to the standard 1 in 100 years flood zoning Australia currently uses in areas now?

I would have thought so but it doesn’t happen that way. In cyclone-prone areas low-lying lands are given a series of zones above high tide level, but that’s taking storm surge into account.

There are also different zonings for locations adjacent to rivers subject to flooding.

But as yet I have seen no sign of special zonings even for areas at risk from coastal erosion.

Yet inland areas get 1 in 50 or 1in 100 year flood zoning. People complain about it and a couple of years later they are flooded out.

Yeah. The Macquarie River is in Dubbo is listed as 1 in 100 year but flooded at least twice in a two year period.

The same happened during the construction of the Warragamba Dam.
