Where I live is between 400 - 500m above sea level and plenty of places flooded around here. It all depends on the terrain, the creeks and rivers and the ability of water to disperse.

Point taken, next time I will be more specific.
In every place you've mentioned the body of water and area's that cause the flooding are at the same level or slightly below the area that has flooded. Like the Mary River in Gympie and surrounding catchment is 5 to 10 m below the properties it flooded and cut off. Geography and terrain and all that. Fair enough.
In my case I live on a hill 42m up. The peak is about 600m x 300m. One side it's straight down to the ocean 1300m away. The other straight down the hill to the main road which is 8m up. To get to me you exit the 8m above road and drive the up the hill another 34m. The next closest body of water is the Mary river, about 2m above sea level 21km away.
The only thing we'd ever have to worry about is a tsunami.
