Is Truganina subject to flooding and bush fire?

Hi all,

I am currently checking some new property developments (Gateway/Bellevue) at Truganina.

I was told that :

"Truganina is subject to flooding and bush fire, then it will bring up your insurance...
Have you been to that place? It is really very empty, may not good for your parents when they coming over.
it is closer to industrial site
and there is a prison over there too..."

Are these true?

Advice is much needed here.

Thank you so much :D
