Personally, I agree with the previous reply: Inala Heights area is the nicest. Azalea, Crocus, Buddleia and Biota streets going west to east, and south-to-north streets from Veronica St to Rosemary St and streets between them. This area doesn't flood, is green and quiet.
There are many lovely streets in Inala, I prefer the higher areas like Azalea Street, the areas near Doolandella are lovely and also the areas bordering Richlands. The nicest streets are near parks, with many tall gum trees.
