No, you need to be able to mitigate the flood waters from entering the house.
If the house had high ceilings and it was only 72mm of water that came in, you could raise the floor a 100mm and be reasonably safe.
With 72cm of water coming into the house you know it "will" fill with water the next time it floods and that could be next month or next year.
Mind you, if the house was being sold at land value only and it was a good size block say 800sqm with 20m frontage you could knock it down and build 2 houses on stilts or raised in some fashion, maybe for car parking only.
As a rule though, I would not buy in a flood zone.
