Can also modify your maintenance formula - I swear the exterior metal, timber and paint work deteriorated a lot quicker in the unit I owned in Cheltenham than "further inland".

Any of them are good as long as you don't get anything on the major roads, and anything within a block of the Nepean.
Only other possible avoid is under the planes at Moorabin Airport.
